VSTO EXCEL中的NEWSHEET事件

    private void ThisWorkbook_Startup(object sender, System.EventArgs e)
    {
        this.NewSheet += new Microsoft.Office.Interop.Excel.WorkbookEvents_NewSheetEventHandler(ThisWorkbook_NewSheet);
    }

    void ThisWorkbook_NewSheet(object Sh)
    {
        MessageBox.Show(((Excel.Worksheet)Sh).Name);
    }

 

 VB.NET的代码如下

Public Class ThisWorkbook

    Private Sub ThisWorkbook_NewSheet(ByVal Sh As Object) Handles Me.NewSheet
        MessageBox.Show(Sh.name)
    End Sub

    Private Sub ThisWorkbook_Startup(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Startup

    End Sub

    Private Sub ThisWorkbook_Shutdown(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Shutdown

    End Sub

End Class

 

同样是object类型的Sh,VB.NET里可以直接调用name属性，而在C#中需要把Sh强制转化为Excel.Worksheet后才能调用Sh的worksheet的属性。

从VBA转到学习C#需要改变的观念真多，希望这点经验对和我一样的VSTO+C#的初学者有点用。
