我有一个允许用户输入数据的Windows表单,当他们点击输入数据按钮时,数据应该从表单转到特定的工作表.代码如下：

imports Excel = Microsoft.Office.Interop.ExcelPublic Class Form_CutListEntry    Dim xApp As New Excel.Application    Dim wss As Microsoft.Office.Tools.Excel.Worksheet    Private Sub Btn_InsertJobInfo_Click(sender As Object,e As EventArgs) Handles Btn_InsertJobInfo.Click        wss = xApp.Worksheets("Job Info")        'Check that all data is entered        If Trim(TxtBx_Customername.Text) = "" Then            TxtBx_Customername.Focus()            MsgBox("Please enter a Customer name")            Exit Sub        End If        If Trim(TxtBx_OrderNum.Text) = "" Then            TxtBx_OrderNum.Focus()            MsgBox("Please enter an Order Number")            Exit Sub        End If        If Trim(TxtBx_CutListAuthor.Text) = "" Then            TxtBx_CutListAuthor.Focus()            MsgBox("Please enter your initials")            Exit Sub        End If       'Write data to excel worksheet.         wss.Cells(3,1) = "Customer name: " + TxtBx_Customername.Text        wss.Cells(4,1) = "Order Number: " + TxtBx_OrderNum.Text        wss.Cells(5,1) = "Todays Date: " + TxtBx_TodaysDate.Text        wss.Cells(6,1) = "Cutting List Prepared By: " + TxtBx_CutListAuthor.Text        Exit Sub    End Sub

(注意我拿出了评论和一些不相关的额外部分,因此下面的详细错误消息包含错误的行号)

我可以从excel中打开窗体,但是当我输入一些数据并单击输入数据时会发生这种情况：

An exception of type 'System.Runtime.InteropServices.COMException' occurred in Toms CutList Maker.dll but was not handled in user codeAdditional information: Exception from HRESulT: 0x800A03EC

在这一行：

wss = xApp.Worksheets("Job Info")

有没有人有机会指出我的写作方向？

如果有人有兴趣,这是完整的错误详细信息：

System.Runtime.InteropServices.COMException was unhandled by user code  ErrorCode=-2146827284  HResult=-2146827284  Message=Exception from HRESulT: 0x800A03EC  Source=Microsoft.Office.Interop.Excel  StackTrace:       at Microsoft.Office.Interop.Excel.ApplicationClass.get_Worksheets()       at Toms_CutList_Maker.Form_CutListEntry.Btn_InsertJobInfo_Click(Object sender,EventArgs e) in d:\tom\documents\visual studio 2013\Projects\Toms CutList Maker\Toms CutList Maker\CutList Entry.vb:line 15       at System.windows.Forms.Control.OnClick(EventArgs e)       at System.windows.Forms.button.OnClick(EventArgs e)       at System.windows.Forms.button.onmouseup(MouseEventArgs mevent)       at System.windows.Forms.Control.WmMouseUp(Message& m,Mousebuttons button,Int32 clicks)       at System.windows.Forms.Control.WndProc(Message& m)       at System.windows.Forms.buttonBase.WndProc(Message& m)       at System.windows.Forms.button.WndProc(Message& m)       at System.windows.Forms.Control.ControlNativeWindow.OnMessage(Message& m)       at System.windows.Forms.Control.ControlNativeWindow.WndProc(Message& m)       at System.windows.Forms.NativeWindow.Callback(IntPtr hWnd,Int32 msg,IntPtr wparam,IntPtr lparam)  InnerException:

解决方法 您无法直接从Excel应用程序中引用工作表.工作表集合是Workbook对象的一部分. Workbooks Collection是Application Object的一部分.

试试这个：

Dim xApp As New Excel.Application Dim wss As Microsoft.Office.Tools.Excel.WorksheetDim wb As Microsoft.Office.Tools.Excel.Workbook....wb = xApp.Workbooks("My Workbook.xlsx") 'replace with your workbook name and proper file extensionwss = wb.Worksheets("Job Info")
