如何在vb.net中使用savefiledialog

我有一个叫做TextEditPro的程序，我刚启动它，我遇到了一个问题

当我有代码点击另存为。。。我不知道如何使用savefiledialog，因此当您单击“另存为”时，它会弹出

有什么帮助吗？

学习使用-for

SaveFileDialog

有一个例子

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
