Method lock in c#

Question

I have one class with these three methods. This class is used by many threads. I would like the Method1 to wait, if Method2 and/or Method3 are running in any threads. Any sugges

Answer 1

I would suggest a ReaderWriterLockSlim (http://msdn.microsoft.com/en-us/library/system.threading.readerwriterlockslim.aspx)

Similar to read operations, Method 2 and Method3 may occur in parallel, while Method1 (like a write operation) would need to wait for those to finish. It's not the regular read/write concurrency situation, but the logic is similar.

public class Class1
{
    private ReaderWriterLockSlim methodLock = new ReaderWriterLockSlim();
    public static void Method1() 
    {
        methodLock.EnterWriteLock();
        try
        {
            //Body function
        }
        finally
        {
            methodLock.ExitWriteLock();
        }
    }

    public static void Method2() 
    {
         methodLock.EnterReadLock();
        try
        {
            //Body function
        }
        finally
        {
            methodLock.ExitReadLock();
        }
    }

    public static void Method3() 
    {
         methodLock.EnterReadLock();
        try
        {
            //Body function
        }
        finally
        {
            methodLock.ExitReadLock();
        }
    }
}
