HOWTO：在 Visual C# .NET 中使用自动化创建 Excel 宏

[code]using Office = Microsoft.Office.Core;
using VBIDE = Microsoft.Vbe.Interop;
using Excel = Microsoft.Office.Interop.Excel;

[code]private void button1_Click(object sender, System.EventArgs e)
{
}

private void button1_Click(object sender, System.EventArgs e)

// Create an instance of Excel.
oExcel = new Excel.Application();

// Add a workbook.
oBook = oExcel.Workbooks.Add(oMissing);

// Create a new VBA code module.
oModule = oBook.VBProject.VBComponents.Add(VBIDE.vbext_ComponentType.vbext_ct_StdModule);

sCode =
"sub VBAMacro()/r/n" +
"   msgbox /"VBA Macro called/"/r/n" +
"end sub";
// Add the VBA macro to the new code module.
oModule.CodeModule.AddFromString(sCode);

try

// Create a new button on the toolbar.
oCommandBarButton = (Office.CommandBarButton) oCommandBar.Controls.Add(

// Assign a macro to the button.
oCommandBarButton.OnAction = "VBAMacro";
