我如何在vb.net中使用savefiledialog

我有一个名为TextEditPro的程序,我刚刚启动它,我遇到了一个问题.

当我有单击另存为的代码…我不知道如何使用savefiledialog所以当你点击另存为它会弹出！

有帮助吗？

学习使用 MSDN – SaveFileDialog的 documentation就是一个例子

Private Sub button1_Click(sender As Object,e As System.EventArgs)
    Dim myStream As Stream
    Dim saveFileDialog1 As New SaveFileDialog()

    saveFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*"
    saveFileDialog1.FilterIndex = 2
    saveFileDialog1.RestoreDirectory = True 

    If saveFileDialog1.ShowDialog() = DialogResult.OK Then
        myStream = saveFileDialog1.OpenFile()
        If (myStream IsNot nothing) Then 
            ' Code to write the stream goes here.
            myStream.Close()
        End If 
    End If 
End Sub
