VB.Net - Excel 表格

简述

VB.Net 支持 Microsoft Excel 2010 的 COM 对象模型与您的应用程序之间的互操作性。

要在您的应用程序中利用这种互操作性，您需要导入命名空间 Microsoft.Office.Interop.Excel 在您的 Windows 窗体应用程序中。

从 VB.Net 创建 Excel 应用程序

让我们按照 Microsoft Visual Studio 中的以下步骤，从创建 Window Forms 应用程序开始： File → New Project → Windows Forms Applications

最后，选择 OK，Microsoft Visual Studio 创建您的项目并显示以下内容 Form1.

在窗体中插入一个 Button 控件 Button1。

向您的项目添加对 Microsoft Excel 对象库的引用。要做到这一点 -

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。

单击确定。

双击代码窗口，填充Button1的Click事件，如下图。


'  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
         .VerticalMoognment = Excel.XlVMoogn.xlVMoognCenter
      End With
      
      ' Create an array to set multiple values at once.
      Dim students(5, 2) As String
      students(0, 0) = "Alex"
      students(0, 1) = "Moo"
      students(1, 0) = "Nuha"
      students(1, 1) = "Moo"
      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

当上面的代码被执行并运行时使用 Start Microsoft Visual Studio 工具栏上可用的按钮，它将显示以下窗口 -

单击按钮将显示以下 excel 表。系统将要求您保存工作簿。
