提示使用vb.net打开excel文件的保存对话框

Question

我使用visual studio 2012，

我想打开“保存对话框”来选择保存文件的位置而不是使用固定路径，以下代码是我想要使用它的示例：

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
    Dim xlsWorkBook As Microsoft.Office.Interop.Excel.Workbook
    Dim xlsWorkSheet As Microsoft.Office.Interop.Excel.Worksheet
    Dim xls As New Microsoft.Office.Interop.Excel.Application

    Dim resourcesFolder = IO.Path.GetFullPath(Application.StartupPath & "\Resources\")
    Dim fileName = "book1.xlsx"

    xlsWorkBook = xls.Workbooks.Open(resourcesFolder & fileName)
    xlsWorkSheet = xlsWorkBook.Sheets("a")

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

    xlsWorkBook.SaveAs("C:\output\book1.xlsx")

    xlsWorkBook.Close()
    xls.Quit()


End Sub

我想更改此路径“C：\\ output \\ book1.xlsx”以保存对话框，因此我可以选择手动保存的位置。

非常感谢..

像这样，不要忘记像我添加的那样使用Marshal类处理com对象。

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
 Dim xls As New Microsoft.Office.Interop.Excel.Application
 Dim xlsWorkBook As Microsoft.Office.Interop.Excel.Workbook
 Dim xlsWorkSheet As Microsoft.Office.Interop.Excel.Worksheet
 Dim resourcesFolder = IO.Path.GetFullPath(Application.StartupPath & "\Resources\")
 Dim fileName = "book1.xlsx"
 xlsWorkBook = xls.Workbooks.Open(resourcesFolder & fileName)
 xlsWorkSheet = xlsWorkBook.Sheets("a")
 xlsWorkSheet.Cells(1, 1) = TextBox1.Text
 Using sfd As New SaveFileDialog
  If sfd.ShowDialog() = DialogResult.OK Then
   xlsWorkBook.SaveAs(sfd.FileName)
   MessageBox.Show(sfd.Filename)
  End If
 End Using
 xlsWorkBook.Close()
 xls.Quit()
 Marshal.FinalReleaseComObject(xlsWorkSheet)
 Marshal.FinalReleaseComObject(xlsWorkBook)
 Marshal.FinalReleaseComObject(xls)
End Sub

打开“另存为”对话框比OneFineDay的答案更加全面的方法（使用相同的方法）。
这将使用指定的目录，文件名，扩展名类型和窗口标题打开“另存为”对话框; 它还会在覆盖任何现有文件之前提示。

Dim dir as String = "C:\output\"
Dim fName As String = "Book1"

Using sfd As New SaveFileDialog
    sfd.InitialDirectory = dir
    sfd.Title = "Save As"
    sfd.OverwritePrompt = True
    sfd.FileName = fName
    sfd.DefaultExt = ".xlsx"
    sfd.Filter = "Excel Workbook(*.xlsx)|"
    sfd.AddExtension = True
    If sfd.ShowDialog() = DialogResult.OK Then
        xlsWorkBook.SaveAs(sfd.FileName)
    End If
End Using

Answer 3

在表单中添加一个openfiledialog，然后......

  With OpenFileDialog1
        .Title = " whatever"
        .InitialDirectory = "c:\"
        .Multiselect = False
        If .ShowDialog() = DialogResult.OK Then
            xlsWorkBook.SaveAs(.FileName)
        End If

结束

你可以用这个：

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
    Dim xlsWorkBook As Microsoft.Office.Interop.Excel.Workbook
    Dim xlsWorkSheet As Microsoft.Office.Interop.Excel.Worksheet
    Dim xls As New Microsoft.Office.Interop.Excel.Application

    Dim resourcesFolder = IO.Path.GetFullPath(Application.StartupPath & "\Resources\")
    Dim fileName = "book1.xlsx"

    xlsWorkBook = xls.Workbooks.Open(resourcesFolder & fileName)
    xlsWorkSheet = xlsWorkBook.Sheets("a")

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

    xlsWorkBook.SaveAs("C:\output\book1.xlsx")
    xls.Application.DisplayAlerts = False
    xlsWorkBook.Close()
    xls.Quit()


End Sub
