Ui.cpp：

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

Answer 1

编译器错误会显示您最初询问的问题的行号。但是，它看起来像你有

namespace Spammer2 {

//lots of usings

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

您需要使用分号结束类定义，而不是命名空间：

namespace Spammer2 {

//lots of usings

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

修改：

由于问题现已更改，如果这是您的所有代码，请向UI.cpp添加main

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

int main()
{
}
