Question

how can i do in C# that my function will be guarded by mutex semaphore a.k.a synchronize function in JAVA

Answer 1

You don’t want synchronize functions like Java – they’re a bad idea because they use a lock construct which other can interfere with. What you want is a lock object. Basically, in the class you want to protect, create a private member variable of type object

private readonly object lock_ = new object();

Then in any method you need to synchronize, use the lock construct to enter and leave the lock automatically:-

public void SomeMethod()
{
    lock(lock_)
    {
         // ...... Do Stuff .........
    }
}
