【问题描述】：

我正在尝试使用 Openfile Dialog 命令导航到一个文件夹，然后选择一些文件。使用这些选定的文件，我正在尝试将这些文件的名称写入 Excel 电子表格。我可以导航到文件夹，但无法将文件写入电子表格。

我有以下代码：

    Dim strFileName As String
    Dim openFile1 As OpenFileDialog = New OpenFileDialog()


    Dim Row As Integer
    Row = 14

    Const Column_A As Integer = 1
    Const Column_B As Integer = 2
    Const Column_C As Integer = 3
    Const Column_D As Integer = 4
    Const Column_E As Integer = 5
    Const Column_F As Integer = 6
    Const Column_U As Integer = 21

    openFile1.Title = "Open File Dialog"    'Title header for dialog box
    openFile1.InitialDirectory = "C:\" 'Initial directory for file dialog box
    openFile1.Filter = "All files (*.*)|" 'Filter all files
    openFile1.Multiselect = True 'Allows the user to select to select multiple files


    Dim Folder As IO.FileInfo()
    Dim FileName As IO.FileInfo

    If openFile1.ShowDialog() = DialogResult.OK Then 'This gives the "ok" to actually open the pop-up window
        For Each FileName In Folder.SelectedItems
            strFileName = openFile1.FileName  'Stores the Filename inside the variable
            Big_Sheet.Cells(Row, Column_B) = FileName
            Row = Row + 1
            Big_Sheet.Cells(Row, Column_C).Value = strFileName 'Shows the variable FilePath
        Next
    End If

【问题讨论】：

您是否遇到任何错误或在任何情况下使用 epplus 或 npoi 等工具来操作 excel 文件会更有效 IMO

【参考方案1】：

可能需要进行更多研究才能写入 excel 文件，例如让您的程序知道您在做什么。

Dim xls As Microsoft.Office.Interop.Excel.Application
Dim xlsWorkBook As Microsoft.Office.Interop.Excel.Workbook
Dim xlsWorkSheet As Microsoft.Office.Interop.Excel.Worksheet

xls = New Microsoft.Office.Interop.Excel.Application
xlsWorkBook = xls.Workbooks.Open("Insert file directory here")
xlsWorkSheet = xlsWorkBook.Sheets("sheet1")

xlsWorkSheet.Cells(1, 1) = TextBox1.Text

希望你能用它来让你更好地理解，研究是关键，我的朋友。
