asp.net里把汉子转为拼音

Imports chinese.MyxChinese
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim mypy As New chinese.MyxChinese
        TextBox2.Text = mypy.MakeSpellCode(TextBox1.Text, DropDownList1.SelectedItem.Value)
    End Sub
注：其中124是字符处理方式，试一下就知道了
