VB.Net - Excel工作表

VB.Net提供对Microsoft Excel 2010的COM对象模型和应用程序之间的互操作性的支持。

要在应用程序中使用此互操作性,您需要在Windows窗体应用程序中导入命名空间Microsoft.Office.Interop.Excel。

从VB.Net创建一个Excel应用程序

让我们从Microsoft Visual Studio中的以下步骤开始创建窗体表单应用程序:文件 - >新建项目 - > Windows窗体应用程序

最后,选择确定,Microsoft Visual Studio创建您的项目并显示以下Form1。

在窗体中插入Button控件Button1。

向项目中添加对Microsoft Excel对象库的引用。 进行以下操作:

  • 从项目菜单中选择添加引用。

  • 在COM选项卡上,找到Microsoft Excel对象库,然后单击选择。

  • 点击OK。

双击代码窗口并填充Button1的Click事件,如下所示。

' Add the following code snippet on top of Form1.vb Imports Excel = Microsoft.Office.Interop.Excel Public Class Form1 Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click Dim appXL As Excel.Application Dim wbXl As Excel.Workbook Dim shXL As Excel.Worksheet Dim raXL As Excel.Range ' Start Excel and get Application object. appXL = CreateObject("Excel.Application") appXL.Visible = True ' Add a new workbook. wbXl = appXL.Workbooks.Add shXL = wbXl.ActiveSheet ' Add table headers going cell by cell. shXL.Cells(1, 1).Value = "First Name" shXL.Cells(1, 2).Value = "Last Name" shXL.Cells(1, 3).Value = "Full Name" shXL.Cells(1, 4).Value = "Specialization" ' Format A1:D1 as bold, vertical alignment = center. With shXL.Range("A1", "D1") .Font.Bold = True .VerticalAlignment = Excel.XlVAlign.xlVAlignCenter End With ' Create an array to set multiple values at once. Dim students(5, 2) As String students(0, 0) = "Zara" students(0, 1) = "Ali" students(1, 0) = "Nuha" students(1, 1) = "Ali" students(2, 0) = "Arilia" students(2, 1) = "RamKumar" students(3, 0) = "Rita" students(3, 1) = "Jones" students(4, 0) = "Umme" students(4, 1) = "Ayman" ' Fill A2:B6 with an array of values (First and Last Names). shXL.Range("A2", "B6").Value = students ' Fill C2:C6 with a relative formula (=A2 & " " & B2). raXL = shXL.Range("C2", "C6") raXL.Formula = "=A2 & "" "" & B2" ' Fill D2:D6 values. With shXL .Cells(2, 4).Value = "Biology" .Cells(3, 4).Value = "Mathmematics" .Cells(4, 4).Value = "Physics" .Cells(5, 4).Value = "Mathmematics" .Cells(6, 4).Value = "Arabic" End With ' AutoFit columns A:D. raXL = shXL.Range("A1", "D1") raXL.EntireColumn.AutoFit() ' Make sure Excel is visible and give the user control ' of Excel's lifetime. appXL.Visible = True appXL.UserControl = True ' Release object references. raXL = Nothing shXL = Nothing wbXl = Nothing appXL.Quit() appXL = Nothing Exit Sub Err_Handler: MsgBox(Err.Description, vbCritical, "Error: " & Err.Number) End Sub End Class

当使用Microsoft Visual Studio工具栏上的“开始”按钮执行并运行上述代码时,将显示以下窗口:

单击按钮将显示以下excel表。 将要求您保存工作簿。
