每次我嘗試運行此程序，它給了我一個錯誤：EDITED

Ui.cpp：

#include "StdAfx.h" 
#include "Ui.h" 

Answer 1

編譯器錯誤會說你最初詢問的問題的行號。 但是，它看起來你有

namespace Spammer2 { 

//lots of usings 

public ref class Ui : public System::Windows::Forms::Form 
{ 
//lots of other stuff 
} 
}; 

你需要以一個分號結束的類定義，沒有命名空間：

namespace Spammer2 { 

//lots of usings 

public ref class Ui : public System::Windows::Forms::Form 
{ 
//lots of other stuff 
}; //<------- 
} //<------- 

編輯：

由於這個問題現在已經如果這是您的所有代碼，請在UI.cpp中添加main

#include "StdAfx.h" 
#include "Ui.h" 

int main() 
{ 
}
