Make a method accessible to one user at a time

Anonymous User 1755 27-Nov-2014

I have got a method that i want only one user can access at a time. I really don't know how to do this. 

public static int add(int a, int b)
{
 int c = a+b;
 return c;
}

and I am calling this method when a user enters data into two text boxes and click the submit button on a asp.net webpage. I don't want other users access to be denied. They should be kept in some sort of queue and when method is finished serving one user next user should be served.

Since you have a static method, you need static Object for locking. 

public class Calculator
{
    private static System.Object lockThis = new System.Object();
 
    public static void Add(int a, int b)
    {   
        lock (lockThis)
        {
            return a+b;
        }
    }
 
}

 lock means, that whenever a Thread accesses that method and it is not locked, it will lock it and run the code. If it is locked it will do nothing until it is unlocked.
