//DisplayComplex类，C++类，编译后变成了值类型，而且方法成员消失了。

//RealMath类，C++类，编译后变成了值类型，而且方法成员消失了。
.class private sequential sealed ansi RealMath extends [mscorlib]System.ValueType

……
DisplayComplex类和RealMath类这两个C++类，方法成员为什么消失了？进一步检查的IL汇编语言程序，还可以看到下列IL汇编语言代码：
……
.module TypesSample1_CPP.exe
……
//DisplayComplex类的Display方法，注意这是一个全局方法（函数），但是仍然使用CIL代码实现。
