介绍

本操作指南解释了如何使用IronXL在Windows的.NET MAUI应用程序中创建和读取Excel文件。让我们开始吧。

IronXL：C# Excel 库

IronXL 是一个用于读写和操作 Excel 文件的 C# .NET 库。它允许用户从头开始创建 Excel 文档，包括 Excel 的内容和外观，以及标题和作者等元数据。该库还支持用户界面定制功能，如设置页边距、方向、页面大小、图像等。生成 Excel 文件不需要任何外部框架、平台集成或其他第三方库。它自成一体，可独立运行。

如何在 .NET Maui 中读取 Excel 文件

安装 C# 库读取 Excel 文件

设计应用程序前端

打开名为 **MainPage.xaml** 的 XAML 页面，用以下代码段替换其中的代码。

XML

上面的代码为我们的基本 .NET MAUI 应用程序创建了布局。它创建了一个标签和两个按钮。一个按钮用于创建 Excel 文件，第二个按钮支持读取和修改 Excel 文件。这两个元素都嵌套在一个 VerticalStackLayout 父元素中，因此它们在所有支持的设备上都是垂直对齐的。

创建 Excel 文件

是时候使用 IronXL 创建 Excel 文件了。打开 MainPage.xaml.cs 文件并在文件中编写以下方法。

private void CreateExcel(object sender, EventArgs e)
    {
        //Create Workbook
        WorkBook workbook = WorkBook.Create(ExcelFileFormat.XLSX);

        //Create Worksheet
        var sheet = workbook.CreateWorkSheet("2022 Budget");

        //Set Cell values
        sheet ["A1"].Value = "January";
        sheet ["B1"].Value = "February";
        sheet ["C1"].Value = "March";
        sheet ["D1"].Value = "April";
        sheet ["E1"].Value = "May";
        sheet ["F1"].Value = "June";
        sheet ["G1"].Value = "July";
        sheet ["H1"].Value = "August";

        //Set Cell input Dynamically
        Random r = new Random();
        for (int i = 2; i <= 11; i++)
        {
            sheet ["A" + i].Value = r.Next(1, 1000);
            sheet ["B" + i].Value = r.Next(1000, 2000);
            sheet ["C" + i].Value = r.Next(2000, 3000);
            sheet ["D" + i].Value = r.Next(3000, 4000);
            sheet ["E" + i].Value = r.Next(4000, 5000);
            sheet ["F" + i].Value = r.Next(5000, 6000);
            sheet ["G" + i].Value = r.Next(6000, 7000);
            sheet ["H" + i].Value = r.Next(7000, 8000);
        }

        //Apply formatting like background and border
        sheet ["A1:H1"].Style.SetBackgroundColor("#d3d3d3");

        decimal avg = sheet ["B2:B11"].Avg();
        decimal max = sheet ["C2:C11"].Max();

        sheet ["A11:H11"].Style.BottomBorder.SetColor("#000000");
        sheet ["A11:H11"].Style.BottomBorder.Type = IronXL.Styles.BorderType.Medium;

VB C#

源代码使用 IronXL 创建了一个包含一个工作表的工作簿，然后使用 "Value "属性为每个单元格设置单元格值。

通过样式属性，我们可以为单元格添加样式和边框。如上图所示，我们可以为单个单元格或单元格区域应用样式。

IronXL 还支持 Excel 公式。自定义 Excel 公式可以精心设计一个或多个单元格。此外，任何 Excel 公式产生的值都可以存储在变量中，以便以后使用。

保存服务 "类将用于保存和查看生成的 Excel 文件。该类已在上面的代码中声明，并将在后面的章节中正式定义。

在浏览器中查看 Excel 文件

打开 MainPage.xaml.cs 文件并编写以下代码。

private void ReadExcel(object sender, EventArgs e)
{
    //store the path of a file
    string filepath="C:\Files\Customer Data.xlsx";
    WorkBook workbook = WorkBook.Load(filepath);
    WorkSheet sheet = workbook.WorkSheets.First();

    decimal sum = sheet ["B2:B10"].Sum();

    sheet ["B11"].Value = sum;
    sheet ["B11"].Style.SetBackgroundColor("#808080");
    sheet ["B11"].Style.Font.SetColor("#ffffff");

    //Save and Open Excel File
    SaveService saveService = new SaveService();
    saveService.SaveAndView("Modified Data.xlsx", "application/octet-stream", workbook.ToStream());

    DisplayAlert("Notification", "Excel file has been modified!", "OK");
}

private void ReadExcel(object sender, EventArgs e)
{
    //store the path of a file
    string filepath="C:\Files\Customer Data.xlsx";
    WorkBook workbook = WorkBook.Load(filepath);
    WorkSheet sheet = workbook.WorkSheets.First();

    decimal sum = sheet ["B2:B10"].Sum();

    sheet ["B11"].Value = sum;
    sheet ["B11"].Style.SetBackgroundColor("#808080");
    sheet ["B11"].Style.Font.SetColor("#ffffff");

    //Save and Open Excel File
    SaveService saveService = new SaveService();
    saveService.SaveAndView("Modified Data.xlsx", "application/octet-stream", workbook.ToStream());

    DisplayAlert("Notification", "Excel file has been modified!", "OK");
}

Private Sub ReadExcel(ByVal sender As Object, ByVal e As EventArgs)
	'store the path of a file
	Dim filepath As String="C:\Files\Customer Data.xlsx"
	Dim workbook As WorkBook = WorkBook.Load(filepath)
	Dim sheet As WorkSheet = workbook.WorkSheets.First()

	Dim sum As Decimal = sheet ("B2:B10").Sum()

	sheet ("B11").Value = sum
	sheet ("B11").Style.SetBackgroundColor("#808080")
	sheet ("B11").Style.Font.SetColor("#ffffff")

	'Save and Open Excel File
	Dim saveService As New SaveService()
	saveService.SaveAndView("Modified Data.xlsx", "application/octet-stream", workbook.ToStream())

	DisplayAlert("Notification", "Excel file has been modified!", "OK")
End Sub

VB C#

源代码加载 Excel 文件，在单元格范围内应用公式，并使用自定义背景和文本颜色进行格式化。随后，Excel 文件将以字节流的形式传输到用户的浏览器。此外，"DisplayAlert "方法会显示一条信息，说明文件已被打开和修改。

保存 Excel 文件

在本节中，我们将定义在前两节中引用的 SaveService 类，该类将把 Excel 文件保存到本地存储器中。

创建一个 "SaveService.cs "类并编写以下代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace MAUI_IronXL
{
    public partial class SaveService
    {
            public partial void SaveAndView(string fileName, string contentType, MemoryStream stream);
    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace MAUI_IronXL
{
    public partial class SaveService
    {
            public partial void SaveAndView(string fileName, string contentType, MemoryStream stream);
    }
}

Imports System
Imports System.Collections.Generic
Imports System.Linq
Imports System.Text
Imports System.Threading.Tasks

Namespace MAUI_IronXL
	Partial Public Class SaveService
			Public Partial Private Sub SaveAndView(ByVal fileName As String, ByVal contentType As String, ByVal stream As MemoryStream)
			End Sub
	End Class
End Namespace

VB C#

接下来，在 Platforms > Windows 文件夹中创建一个名为 "SaveWindows.cs "的类，并添加以下代码。


using Windows.Storage;
using Windows.Storage.Pickers;
using Windows.Storage.Streams;
using Windows.UI.Popups;

namespace MAUI_IronXL

    public partial class SaveService

            string extension = Path.GetExtension(fileName);
            //Gets process windows handle to open the dialog in application process.
            IntPtr windowHandle = System.Diagnostics.Process.GetCurrentProcess().MainWindowHandle;
            if (!Windows.Foundation.Metadata.ApiInformation.IsTypePresent("Windows.Phone.UI.Input.HardwareButtons"))
            {
                //Creates file save picker to save a file.
                FileSavePicker savePicker = new FileSavePicker();
                savePicker.DefaultFileExtension = ".xlsx";
                savePicker.SuggestedFileName = fileName;
                //Saves the file as Excel file.
                savePicker.FileTypeChoices.Add("XLSX", new List<string>() { ".xlsx" });

                WinRT.Interop.InitializeWithWindow.Initialize(savePicker, windowHandle);

            {
                StorageFolder local = ApplicationData.Current.LocalFolder;
                stFile = await local.CreateFileAsync(fileName, CreationCollisionOption.ReplaceExisting);
            }
            if (stFile != null)
            {
                using (IRandomAccessStream zipStream = await stFile.OpenAsync(FileAccessMode.ReadWrite))
                {
                    //Writes compressed data from memory to file.
                    using(Stream outstream = zipStream.AsStreamForWrite())
                    {
                     outstream.SetLength(0);
                     //Saves the stream as file.
                     byte [] buffer = outstream.ToArray();
                     outstream.Write(buffer, 0, buffer.Length);
                     outstream.Flush();
                    }
                }
                //Create message dialog box.
                MessageDialog msgDialog = new("Do you want to view the document?", "File has been created successfully");
                UICommand yesCmd = new("Yes");
                msgDialog.Commands.Add(yesCmd);
                UICommand noCmd = new("No");
                msgDialog.Commands.Add(noCmd);

                WinRT.Interop.InitializeWithWindow.Initialize(msgDialog, windowHandle);

                //Showing a dialog box.
                IUICommand cmd = await msgDialog.ShowAsync();
                if (cmd.Label == yesCmd.Label)
                {
                    //Launch the saved file.
                    await Windows.System.Launcher.LaunchFileAsync(stFile);
                }
            }
        }
    }
}
