Lock several pieces of code

I have an asp.net website where I would like to prevent concurrent access to certain pieces of code. Since every page request will get a thread of its own - that might be a problem.

If this were only one piece of code - I'd lock it. However, there are actually several related methods. If one thread enters one of them - I'd like to prevent other threads from entering any of them.

How do I achieve that?

Well, you could put a lock on some object that is accessible by all of the code blocks - ideally it would be an internal object (or private if all of the code is in one class) so that no external code could lock it and block your code:

public class Global : System.Web.HttpApplication
{
    internal static readonly object LockObject = new Object();
    ...
}

... meanwhile ...

lock(Global.LockObject)
{
   // code block 1 
}

... elsewhere ...

lock(Global.LockObject)
{
   // code block 2
}
