USING IRONZIP

.NET MAUI Data Extraction SDK with IronZIP

.NET MAUI, or .NET Multi-platform App UI, is a framework for building cross-platform applications. It allows developers to create applications with a single codebase that runs on Windows, macOS, iOS, Android, and other devices. Similar to React Native, but it uses C# instead of JavaScript.

.NET MAUI allows C# developers to build hassle-free mobile applications and desktop apps from a single environment. Microsoft .NET MAUI provides comprehensive documentation and resources to help developers streamline and optimize the app development process.

In this article, we'll explore the integration of IronZIP, a powerful C# ZIP Archive Library, with .NET MAUI for data extraction purposes.

How to Extract Data from Zip Archives

  1. Create a Visual Studio .NET MAUI Project
  2. Install the C# Zip Library using NuGet
  3. Design the Data Extraction App Interface
  4. Implement Create Zip and Extract Zip Methods
  5. Run the application and verify the results

Steps to Create a Zip Extractor

Step 1: Design App's Interface

In this section, we'll focus on designing the user interface for your .NET MAUI application. Open the MainPage.xaml file in your project folder and add the necessary XAML code to create a user-friendly interface.

Here, we'll need two buttons, one for creating zip files and a second for extracting zip files. A few labels are also required to provide appropriate messages. The following code example shows the XAML code of the design:

Step 2: Implement the Code

1. Create Zip

Open the MainPage.xaml.cs file and create the "Create Zip" functionality. Implement the OnSelectFilesButtonClicked method to allow opening the FilePicker and selecting multiple files of any type for creating a zip file.

Then, create a list of all the paths from selected files. Finally, pass it to the CreateZip method, where IronZIP will create a zip file using all the file paths seamlessly within a second.

The following code example shows how to achieve this task.

private async void OnSelectFilesButtonClicked(object sender, EventArgs e)
{
    try
    {
        var status = await Permissions.RequestAsync<Permissions.StorageRead>();
        if (status != PermissionStatus.Granted)
        {
            await DisplayAlert("Alert!", "Storage Access Denied", "Ok");
            return;
        }
        // Select multiple files of any type
        var results = await FilePicker.PickMultipleAsync();
        if (results != null)
        {
            var selectedFilePaths = new List<string>();
            foreach (var file in results)
            {
                // Add file full path to the list one by one
                selectedFilePaths.Add(file.FullPath);
            }
            CreateZip(selectedFilePaths);
        }
    }
    catch (Exception ex)
    {
        Console.WriteLine($"Error: {ex.Message}");
    }
}
private async void OnSelectFilesButtonClicked(object sender, EventArgs e)
{
    try
    {
        var status = await Permissions.RequestAsync<Permissions.StorageRead>();
        if (status != PermissionStatus.Granted)
        {
            await DisplayAlert("Alert!", "Storage Access Denied", "Ok");
            return;
        }
        // Select multiple files of any type
        var results = await FilePicker.PickMultipleAsync();
        if (results != null)
        {
            var selectedFilePaths = new List<string>();
            foreach (var file in results)
            {
                // Add file full path to the list one by one
                selectedFilePaths.Add(file.FullPath);
            }
            CreateZip(selectedFilePaths);
        }
    }
    catch (Exception ex)
    {
        Console.WriteLine($"Error: {ex.Message}");
    }
}
Private Async Sub OnSelectFilesButtonClicked(ByVal sender As Object, ByVal e As EventArgs)
	Try
		Dim status = Await Permissions.RequestAsync(Of Permissions.StorageRead)()
		If status <> PermissionStatus.Granted Then
			Await DisplayAlert("Alert!", "Storage Access Denied", "Ok")
			Return
		End If
		' Select multiple files of any type
		Dim results = Await FilePicker.PickMultipleAsync()
		If results IsNot Nothing Then
			Dim selectedFilePaths = New List(Of String)()
			For Each file In results
				' Add file full path to the list one by one
				selectedFilePaths.Add(file.FullPath)
			Next file
			CreateZip(selectedFilePaths)
		End If
	Catch ex As Exception
		Console.WriteLine($"Error: {ex.Message}")
	End Try
End Sub

Next, implement the CreateZip method. IronZIP's IronArchive class takes the path where the zip file is to be created. Looping through each selected file path, they're added to the zip file by the Add method.

When the files are added, a confirmation message is displayed using DisplayAlert.

private async void CreateZip(List<string> selectedFilePaths)
{
    var path = "E:\\output.zip";
    // Create a Zip
    using (var archive = new IronArchive(path))
    {
        // Add files to the ZIP
        foreach (var file in selectedFilePaths)
        {
            archive.Add(file);
        }
    }
    await DisplayAlert("Congratulations", "All files added to " + path, "Ok");
}
private async void CreateZip(List<string> selectedFilePaths)
{
    var path = "E:\\output.zip";
    // Create a Zip
    using (var archive = new IronArchive(path))
    {
        // Add files to the ZIP
        foreach (var file in selectedFilePaths)
        {
            archive.Add(file);
        }
    }
    await DisplayAlert("Congratulations", "All files added to " + path, "Ok");
}
Private Async Sub CreateZip(ByVal selectedFilePaths As List(Of String))
	Dim path = "E:\output.zip"
	' Create a Zip
	Using archive = New IronArchive(path)
		' Add files to the ZIP
		For Each file In selectedFilePaths
			archive.Add(file)
		Next file
	End Using
	Await DisplayAlert("Congratulations", "All files added to " & path, "Ok")
End Sub

2. Extract Zip

Now, we'll create the "Extract Zip" functionality. Again, in the MainPage.xaml.cs file, implement the OnSelectFileButtonClicked method to allow opening the FilePicker and selecting a single zip file for extraction.

The selected file's full path is set to a string variable and sent to the ExtractZip method, where IronZIP performs the extraction. The code goes as follows:

private async void OnSelectFileButtonClicked(object sender, EventArgs e)
{
    try
    {
        var status = await Permissions.RequestAsync<Permissions.StorageRead>();
        if (status != PermissionStatus.Granted)
        {
            await DisplayAlert("Alert!", "Storage Access Denied", "Ok");
            return;
        }
        // Select a single file of any type
        var result = await FilePicker.PickAsync();
        if (result != null)
        {
            // Add File Full Path to the list one by one
            var selectedFile = result.FullPath;
            ExtractZip(selectedFile);
        }
    }
    catch (Exception ex)
    {
        Console.WriteLine($"Error: {ex.Message}");
    }
}
private async void OnSelectFileButtonClicked(object sender, EventArgs e)
{
    try
    {
        var status = await Permissions.RequestAsync<Permissions.StorageRead>();
        if (status != PermissionStatus.Granted)
        {
            await DisplayAlert("Alert!", "Storage Access Denied", "Ok");
            return;
        }
        // Select a single file of any type
        var result = await FilePicker.PickAsync();
        if (result != null)
        {
            // Add File Full Path to the list one by one
            var selectedFile = result.FullPath;
            ExtractZip(selectedFile);
        }
    }
    catch (Exception ex)
    {
        Console.WriteLine($"Error: {ex.Message}");
    }
}
Private Async Sub OnSelectFileButtonClicked(ByVal sender As Object, ByVal e As EventArgs)
	Try
		Dim status = Await Permissions.RequestAsync(Of Permissions.StorageRead)()
		If status <> PermissionStatus.Granted Then
			Await DisplayAlert("Alert!", "Storage Access Denied", "Ok")
			Return
		End If
		' Select a single file of any type
		Dim result = Await FilePicker.PickAsync()
		If result IsNot Nothing Then
			' Add File Full Path to the list one by one
			Dim selectedFile = result.FullPath
			ExtractZip(selectedFile)
		End If
	Catch ex As Exception
		Console.WriteLine($"Error: {ex.Message}")
	End Try
End Sub
$vbLabelText   $csharpLabel

Next, create the ExtractZip method. In this method, set the path to the output folder where you want to extract the files.

Using IronZIP's ExtractArchiveToDirectory method, pass the selected file path and output path. This method seamlessly converts and transfers all the files in the zip to the output folder. Finally, a confirmation message is shown on successful extraction.

The code goes as follows:

private async void ExtractZip(string selectedFilePath)
{
    var path = "E:\\Extracted Files";
    IronArchive.ExtractArchiveToDirectory(selectedFilePath, path);
    await DisplayAlert("Congratulations", "All files extracted to " + path, "Ok");
}
private async void ExtractZip(string selectedFilePath)
{
    var path = "E:\\Extracted Files";
    IronArchive.ExtractArchiveToDirectory(selectedFilePath, path);
    await DisplayAlert("Congratulations", "All files extracted to " + path, "Ok");
}
Private Async Sub ExtractZip(ByVal selectedFilePath As String)
	Dim path = "E:\Extracted Files"
	IronArchive.ExtractArchiveToDirectory(selectedFilePath, path)
	Await DisplayAlert("Congratulations", "All files extracted to " & path, "Ok")
End Sub
