C# 和 MFC字符串相互传递

MFC代码：

void getString(LPTSTR AResult,LPTSTR AIn) {lstrcpy(AResult,_T("一个测试!"));AfxMessageBox(AIn);} 

C#调用代码：

private void button1_Click(object sender, EventArgs e) { Encoding encoder = Encoding.Unicode; byte[] buff = encoder.GetBytes("测试"); string value = encoder.GetString(buff); byte[] outvalue = new byte[200]; ArcsCtrl.getString(outvalue, buff); MessageBox.Show(encoder.GetString(outvalue)); }
