VC.NET 需要注意的一些问题

 String^ abc = gcnew String();
 String^ abc = nullptr

override .net 类方法：

void  Reset() override
{....}

属性：

property virtual int Count
{
    int get(){return this->m_Count;}
    set(int value){this->m_Count=value;}
}

索引：

virtual property int default[int]
{
    int get(int index){return this->m_Index;}
    void set(int index, int value){this->m_Index=value;}
}

就是c#中的：

public int this[int index]
{
    get{return this.m_Index;}
    set{this.m_Index=value;}
}

数组：

array<ItemType>^ items;
cli::array<ItemType^>^ items;

泛型：

generic <class ItemType>
public ref class ItemCollection{}

类型：

c#:

typeof(someclass);

C++:

someclass::typeid;

namespace 这点很烦人

namespace A
{
    namespace B
    {
    }
}

同名不同返回類型的函數（繼承接口）

virtual someTypename^ somemethodname() = basetypename::somemethod
{
     return this->m_InnerList->GetEnumerator();
}

定义类,结构

public ref class Block {};         // reference class
public value class Vector {};      // value class
public interface class IFooBar {}; // interface class

public ref class Shape abstract {};
public ref class Shape2D abstract : public Shape{};

sealed class

public ref class String sealed {};

折叠代码

#pragma region sometext
#pragma endregion sometext

定义.net中的enum:

public enum class eRtsState
    :int
{
    LoginFailed = -2,
    ConnectFailed = -1,
    Closed = 0,
    Init = 1,
    Connecting = 2,
    Connected,
    Logining,
    Logined,
    LoadingExchange,
    LoadingContracts,
    Opened,
};

定义Property:

public:
    property eRtsState State
    {
        eRtsState get()
        {
            return (eRtsState)(int)_mdapi->State();
        }
    }

也可以直接使用

property eRtsState State;
