正在研究Com中，不过好像也不能使用Static修饰。
C++的Dll：
// TestDll.h
#pragma once
using namespace System;
namespace TestDll
{
public ref class TestDllC
{
private:
int iPid;
static int iBasePid;
public:
TestDllC();
~TestDllC();
!TestDllC();
static TestDllC();
public:
int TestFunc();
};
}
C++Dll的TestDll.cpp
// 这是主 DLL 文件。
#include "stdafx.h"
#include "TestDll.h"
namespace TestDll
{
TestDllC::TestDllC()
{
iPid = iBasePid++;
}
TestDllC::~TestDllC()
{
}
TestDllC::!TestDllC()
{
// delete pThis;
}
static TestDllC::TestDllC()
{
iBasePid = 0;
}
int TestDllC::TestFunc()
{
return iPid;
}
}
程序集说明里添加了关于强命名的几个小属性，也就是随便SN -k了一个文件 然后添加进去
C# Com添加了上述Dll的引用代码如下：
using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;
using TestDll;
namespace MyCom
{
[ComVisible(true)]
[Guid("96C2B813-A76C-41a5-93D6-A4B995F70AA0")]
public interface IComTest1
{
static IComTest1 GetInstance();
void Initialize();
void Dispose();
int Test();
}
[Guid("ACA89BB6-2E04-42d7-840D-ECAEA5CCF5C1"), InterfaceType(ComInterfaceType.InterfaceIsIDispatch)]
public interface MyCom_Events
{
}
[ProgId("MyCom.MyClass")]
public class ComTest1:IComTest1
{
private static TestDllC iTestDllC;
private static IComTest1 iTestCom;
private ComTest1()
{
}
static ComTest1()
{
iTestCom = null;
iTestDllC = new TestDllC();
}
public void Initialize()
{
}
public void Dispose()
{
}
public int Test()
{
return iTestDllC.TestFunc();
}
static public IComTest1 GetInstance()
{
if (iTestCom == null)
{
lock (iTestCom)
{
if (iTestCom == null)
{
iTestCom = new ComTest1();
}
}
}
return iTestCom;
}
}
}
编译提示错误 1 修饰符“static”对该项无效
求如何在对Com调用GetInstance方法实现返回一个引用或者实例指针之类的？
