所以我正在编写一个Windows窗体应用程序，因此当我运行它时会抛出一个不应该抛出的错误。它抛出“语法错误：丢失;使用前”
我尝试在前一行放一个，但它没有用。
文件问题是这个
// 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（不想填满整个堆栈溢出页面。）http://pastebin.com/324mpCps
所有帮助都得到了赞赏！
答案 0 :(得分：1)
你刚刚与括号混淆了。
首先，删除Rock Paper Scisors.cpp文件中的最后一个'}'。最后，这就是正确的Form1.h文件的外观：
#include<time.h>
#include<stdlib.h>
#include<stdio.h>
#include<ctime>
#include<cstdlib>

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