所以我正在编写一个 Windows 窗体应用程序，所以当我运行它时，它会抛出一个它不应该抛出的错误。它抛出“语法错误：缺少；使用前”

我尝试将一个放在前一行，但它不起作用。

有问题的文件是这个

// Rock Paper Scisors.cpp : main project file.

#include "stdafx.h"
#include "Form1.h"

using namespace RockPaperScisors;

[STAThreadAttribute]
int main(array<System::String ^> ^args)
{
    // Enabling Windows XP visual effects before any controls are created
    Application::EnableVisualStyles();
    Application::SetCompatibleTextRenderingDefault(false); 

    // Create the main window and run it
    Application::Run(gcnew Form1());
    return 0;
}}

stdafx.h 是 MS Visual C++ Express 的一部分，无论如何，Form1.h 的代码可以在这个 pastebin 中找到（不想淹没整个堆栈溢出页面。）http://pastebin.com/324mpCps

感谢所有帮助！

你只是混淆了括号。

首先，删除 Rock Paper Scisors.cpp 文件中的最后一个 '}'。其次，这是正确的 Form1.h 文件的外观：

#include<time.h>
#include<stdlib.h>
#include<stdio.h>
#include<ctime>
#include<cstdlib>

#pragma once

namespace RockPaperScisors {

    using namespace System;

}

我只在末尾添加了一个括号，关闭了类中的最后一个方法。由于 Visual Studio 2010 及更早版本不支持 C++/CLI 中的 IntelliSense，因此此类项目中可能会出现错误。
