请问高手，为什么openfiledialog对话框获取的filename属性值不能被streamwriter写进流文档呢？

    Private Sub Button8_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button8.Click
            Dim svsys As New IO.StreamWriter("sys.ini", False)
            svsys.WriteLine(TextBox1.Text)
            svsys.WriteLine(TextBox4.Text) '就是这一条，手工输入的能写进去，用OpenFileDialog对话框获取的值就写不进去
            svsys.Close()
    End Sub

    Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)

    End Sub
    Private Sub TextBox4_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)

    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        OpenFileDialog1.ShowDialog()
        TextBox4.Text = OpenFileDialog1.FileName.ToString
    End Sub

二楼能正常保存吗？我又试了一下还是不行啊，我补传了附件上来了，手工输入到路径文本框的字符就能保存，openfile对话框的name属性传到路径文本框的字符就不能保存。
