c語言-MessageBox和DialogResult程序報錯

MessageBox和DialogResult程序報錯

VC++6.0網上找的點擊“是”進入下一步的代碼，然後我用main函數執行下面的代碼
string message = "You did not enter a server name. Cancel this operation?";
string caption = "No Server Name Specified";
MessageBoxButtons buttons = MessageBoxButtons.YesNo;
DialogResult result;

    //顯示MessageBox.
    result = MessageBox.Show(this, message, caption, buttons);

    //如果點擊的是"YES"按鈕,將form關閉.
    if(result == DialogResult.Yes)
    {
        // Closes the parent form.
        this.Close();
    }

然後報了錯，請問是什麼問題，最好能給一份完整的代碼，本人新手

最佳回答：

 這代碼是C#的，不是C++的。

C++的寫法是
if (MessageBox(NULL. "You did not enter a server name. Cancel this operation?", "No Server Name Specified", MB_YESNO) == IDYES)
//接下去的代碼
