"C # Multithreaded Programming combat" 2.4 Semaphoreslim

That's a lot easier.

Understanding is also very well understood.

Better understanding than the previous mutex.

What does this Semaphoreslim do?

is to restrict access to the thread. Like saying only two at a time, only three such threads at a time access resources.

It's a bit like a lock method that adds no markup.

First on the code

  classProgram {StaticSemaphoreslim Slim =NewSemaphoreslim (4);//limit the number of threads that are accessed once        Static voidMain (string[] args) {             for(inti =1; I <=6; i++)            {                varName ="thread:_"+i; ints =2+2*i; vart =NewThread (() =Accessdatabase (name, s));            T.start ();        } console.readkey (); }        Static voidAccessdatabase (stringNameintseconds) {Console.WriteLine ($"{name} Waites to"); Slim. Wait ();//Thread WaitsConsole.WriteLine ($"{name} get data");            Thread.Sleep (timespan.frommilliseconds (seconds)); Console.WriteLine ($"{name} is done"); Slim. Release ();//Releasing ThreadsConsole.WriteLine ($"{name} is close"); }    }

This is really good and convenient.

The way of use is also particularly simple.

An instantiation of

Two Waiting threads

Three-release thread

Just so ez.

1    New Semaphoreslim (4); // limit the number of threads that are accessed once 2    Slim. Wait (); // Thread Waits       3    Slim. Release (); // Releasing Threads

This will be understood by a dozen times.

No more talking.
