How can I define my application to open only one time after click on its exe file over and over?

我一直在应用程序的入口处完成此操作：

bool onlyInstance = false;

Mutex m = new Mutex(true, "MyUniqueMutextName", out onlyInstance);
if (!onlyInstance)
{
    return;
}

GC.KeepAlive(m);

There are several related questions on Stack Overflow for Single Instance Applications:
