I need to create a Thread-safe static variable in C# .Net

Question

ok, its a little more complicated than the question.

class A
{
   static int needsToBeThreadSafe = 0;

   public static void M1()
   {
     needsToBeThreadSa         


        

Answer 1

How About:

public static void M1()
{
    Interlocked.Exchange( ref needsToBeThreadSafe, RandomNumber() );
}

public static void M2()
{
    print( Interlocked.Read( ref needsToBeThreadSafe ) );
}
