如何在 C# Windows 應用程序中提取 ZIP 文件

1. How to Extract ZIP File in C# Windows Application

1. Create a new C# Windows application project in Visual Studio.
2. Install the C# ZIP Extraction library IronZIP using NuGet Package Manager.
3. Design the form to add buttons, text fields, and labels.
4. Get the path of the ZIP file using the openFileDialog object.
5. Extract content from the ZIP file and save it in the destination folder using the ExtractArchiveToDirectory method.

2. Introducing IronZIP in C#

IronZIP is a versatile and feature-rich C# library that provides developers with the tools to work seamlessly with ZIP files. It offers a comprehensive set of functionalities for creating, extracting, and manipulating ZIP archives, making it an excellent choice for developers looking to enhance their applications with ZIP file support. IronZIP is known for its simplicity, flexibility, and performance, making it a preferred choice as a ZIP file manipulator for many C# developers.

3. Creating a New Windows Application in Visual Studio

To get started, open Visual Studio and create a new Windows Forms Application project.

1. Open Visual Studio: Begin by launching Visual Studio on your computer.
2. Create a New Project: Once Visual Studio is open, select the option to create a new project.
3. Choose Windows Forms Application: In the new project dialog, choose the "Windows Forms Application" template. This template will serve as the starting point for our ZIP file extraction application.
4. Set Project Name: Give your project a meaningful and descriptive name that reflects its purpose. This will help you identify and manage your projects effectively.
5. Select Target Framework: Ensure that you select the appropriate target framework for your application. This choice depends on the compatibility requirements of your project.
6. Finish and Create: Complete the project creation process by clicking the "Create" or "Finish" button, depending on the version of Visual Studio you're using.

4. Installing IronZIP

Before diving into the code, you need to install the IronZIP library. You can do this easily by using the NuGet Package Manager within Visual Studio. Open the Package Manager Console and run the following command:

Install-Package IronZip

This command will download and install the IronZIP library, along with any dependencies required for seamless integration with your project.

5. Designing a Form for ZIP File Extraction

Next, design a simple Windows Form that will serve as the user interface for your ZIP file extraction application. Add controls such as a Button for triggering the extraction process and a FileDialog to allow users to browse and select the ZIP file they want to extract from.

private void button1_Click(object sender, EventArgs e)
{
    // Create and configure an OpenFileDialog instance
    OpenFileDialog openFileDialog = new OpenFileDialog();
    openFileDialog.Title = "Select a File";

    // Display the OpenFileDialog and check if the user selected a file
    if (openFileDialog.ShowDialog() == DialogResult.OK)
    {
        // Display the selected file path in a TextBox or perform any other action
        textBox1.Text = openFileDialog.FileName;
    }
}

private void button1_Click(object sender, EventArgs e)
{
    // Create and configure an OpenFileDialog instance
    OpenFileDialog openFileDialog = new OpenFileDialog();
    openFileDialog.Title = "Select a File";

    // Display the OpenFileDialog and check if the user selected a file
    if (openFileDialog.ShowDialog() == DialogResult.OK)
    {
        // Display the selected file path in a TextBox or perform any other action
        textBox1.Text = openFileDialog.FileName;
    }
}

Private Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs)
	' Create and configure an OpenFileDialog instance
	Dim openFileDialog As New OpenFileDialog()
	openFileDialog.Title = "Select a File"

	' Display the OpenFileDialog and check if the user selected a file
	If openFileDialog.ShowDialog() = DialogResult.OK Then
		' Display the selected file path in a TextBox or perform any other action
		textBox1.Text = openFileDialog.FileName
	End If
End Sub

private void button2_Click(object sender, EventArgs e)
{
    try
    {
        // Extract the selected ZIP file to the "extracted" directory
        IronZipArchive.ExtractArchiveToDirectory(textBox1.Text, "extracted");

        // Notify the user of successful extraction
        MessageBox.Show("File Successfully Unarchived", "Success", MessageBoxButtons.OK, MessageBoxIcon.Information);
    }
    catch (Exception ex)
    {
        // Handle any errors that occur during extraction
        MessageBox.Show($"Error extracting ZIP file: {ex.Message}", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
    }
}

private void button2_Click(object sender, EventArgs e)
{
    try
    {
        // Extract the selected ZIP file to the "extracted" directory
        IronZipArchive.ExtractArchiveToDirectory(textBox1.Text, "extracted");

        // Notify the user of successful extraction
        MessageBox.Show("File Successfully Unarchived", "Success", MessageBoxButtons.OK, MessageBoxIcon.Information);
    }
    catch (Exception ex)
    {
        // Handle any errors that occur during extraction
        MessageBox.Show($"Error extracting ZIP file: {ex.Message}", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error);
    }
}

Private Sub button2_Click(ByVal sender As Object, ByVal e As EventArgs)
	Try
		' Extract the selected ZIP file to the "extracted" directory
		IronZipArchive.ExtractArchiveToDirectory(textBox1.Text, "extracted")

		' Notify the user of successful extraction
		MessageBox.Show("File Successfully Unarchived", "Success", MessageBoxButtons.OK, MessageBoxIcon.Information)
	Catch ex As Exception
		' Handle any errors that occur during extraction
		MessageBox.Show($"Error extracting ZIP file: {ex.Message}", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)
	End Try
End Sub
