【原创】C#与C之间的进程互斥同步示例

C#程序启动起来之后，等待C++发送操作。
在C++程序，按一次回车，C#程序执行一次循环
。。。。。。

C++

#include 
#include 

const WCHAR mutextName[] = L"five_exe_mutex_sync";
HANDLE g_hMutex;

int main()
{
	g_hMutex = CreateMutex(NULL, FALSE, mutextName);
	while (true)
	{
		WaitForSingleObject(g_hMutex, INFINITE);

		printf("按回车，继续");
		getchar();

		ReleaseMutex(g_hMutex);
	}
	CloseHandle(g_hMutex);
}

C#

string MutexName = "five_exe_mutex_sync";
Mutex? mutex;

OpenMutex();
while (true)
{
    if (mutex.SafeWaitHandle.IsClosed == false && mutex.SafeWaitHandle.IsInvalid == false)
    {
        Console.WriteLine("waite......");
        try
        {
            mutex.WaitOne();
            Console.WriteLine("获取互斥访问权! 访问资源完毕");
            mutex.ReleaseMutex();
            mutex.Close();
        }
        catch { }
       
    }
    else
    {
        OpenMutex();
    }
};

void OpenMutex()
{
    while (Mutex.TryOpenExisting(MutexName, out mutex) == false)
    {
        Console.WriteLine("waite...mutex...");
        Thread.Sleep(500);
    }
}
