C++/CLI 托管C++之类、属性封装【7】

标签：c#   c++   cli   c++cli   

CLI封装类时，涉及确定性析构与非确定性析构，属性封装使用property。

【1】C++导出类

class  EXPORTDLL_CLASS CAddSub
{
public:
    CAddSub(){
        m_len = 0;
    }
    ~CAddSub(){

    }

public:
    int  Add(int x, int y){
        return x+y;
    }

    int  Sub(int x, int y){
        return x-y;
    }

    int  GetLength()
    {
        return(m_len);
    }

    void  SetLength(int len){
        m_len = len;
    }

private:
    int   m_len;
};

    /// <summary>
    /// 4 类测试
    /// </summary>
    public ref class AddSubCls
    {
    public:        
        AddSubCls()
        {
            m_pCls = new CAddSub();
        }

        !AddSubCls() //确定性释放
        {
            delete m_pCls;
        }

        ~AddSubCls() //非确定性释放
        {
            this->!AddSubCls();
        }

    public:
        Int32  Add(Int32 x, Int32 y)
        {
            return(m_pCls->Add(x, y));   
        }

        Int32  Sub(Int32 x, Int32 y)
        {
            return(m_pCls->Sub(x, y));  
        }

        property Int32 Length
        {
            Int32 get()
            {
                return(m_pCls->GetLength());
            }

            void set(Int32 len)
            {
                m_pCls->SetLength(len);
            }
        }
        
    private:
        CAddSub     *m_pCls;
    };

AddSubCls addSubCls = new AddSubCls();
int sum = addSubCls.Add(1, 4);
addSubCls.Length = 6;
