VB.net 2019打开Excel表格

尝试了无数遍...还是不行。已经添加了Excel16的com。

Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
        Dim AppXls As Microsoft.Office.Interop.Excel.Application    '声明Excel对象
        Dim AppWokBook As Microsoft.Office.Interop.Excel.Workbook    '声明工作簿对象
        Dim AppSheet As New Microsoft.Office.Interop.Excel.Worksheet    '声明工作表对象

        AppXls = New Microsoft.Office.Interop.Excel.Application     '实例化Excel对象
        AppXls.Workbooks.Open("E:\SCA order\Sca Order\test\test.xls")                    '打开已经存在的EXCEL文件
        AppXls.Visible = True                                       '使Excel可见

    End Sub
