Call-time Example:
Note: It is best to write in the KeyUp event when calling

private void Txtmaterialname_keyup (object sender, KeyEventArgs e)
{

Incoming string or text box content to be processed, generate a mnemonic
This.txtNnemonicCode.Text = MyTool.PinYinConver.CreateNnemonicCode (This.txtMaterialName.Text);

Incoming string or text box content to be processed, generate phonetic code
This.txtSpellCode.Text = MyTool.PinYinConver.CreateSpellCode (This.txtMaterialName.Text);
