就是这个结构体阿~消息应该是在lpData这个指针指向的内存里，我是这么认为的hoho
今天来了好多bug要改可能没时间给你详细解释咯。/// <summary>

typedef struct data
{

char s1[100];
unsigned int ID;
char address[256];
char Name[256]
}
例如，我在vc里的一个结构体，在c#里怎么声明这个结构体，和作为一个结构体的数据在两个进程间用WM_COPYDATA在两个进程间发送和接受，谢谢了，希望回答问题的哥们给我搞个例子好吗，谢谢，我的油箱[email protected]

我公司里面对163邮箱有屏蔽,代码就贴在这里吧,见谅.
