真的奇怪的Windows窗體C++錯誤

Question

所以我正在寫一個Windows窗體應用程序，所以當我運行它時會拋出一個錯誤，它不應該拋出。它會拋出一個「語法錯誤：丟失;使用之前」

我試着把一個放在前一行，它沒有工作。

有問題的文件是這樣的

// 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; 
}} 

的stdafx.h是微軟的Visual C++快遞的一部分，反正對於Form1.h的代碼可以在這個引擎收錄發現（不想淹沒了整個堆棧溢出頁面。）http://pastebin.com/324mpCps

All Help isappreciated！

Answer 1

你剛剛與括號混淆。

首先，刪除Rock Paper Scisors.cpp文件中的最後一個'}'。 Secodnly，這是正確的Form1.h文件應該是什麼樣子：

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

#pragma once

我只加了一個支架接近尾聲，收盤在課堂上的最後一個方法。由於Visual Studio 2010及更早版本不支持C++/CLI中的智能感知，因此這些項目中可能會出現錯誤。
