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此互操作性,您需要导入名称空间 Windows窗体应用程序中的Microsoft.Office.Interop.Excel .
从VB.Net创建Excel应用程序
让我们开始吧通过在Microsoft Visual Studio中执行以下步骤来创建窗体表单应用程序: File → 新项目 → Windows窗体应用程序
最后,选择确定,Microsoft Visual Studio创建项目并显示以下 Form1 .
在窗体中插入一个Button控件Button1.
在项目中添加对Microsoft Excel Object Library的引用.要做这个&减去;
-
从项目菜单中选择添加参考.
-
在COM选项卡上,找到Microsoft Excel对象库,然后单击选择.
-
单击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,它将显示以下窗口 :
单击按钮将显示以下Excel工作表.系统将要求您保存工作簿.
