Thread Local Storage For C# Class Library

Question

I have a very old but very large library which I am considering converting to a C# class library. The existing library uses a lot of global variables stored in the TLS. C# h

Presuming you're going to use .NET 4.0, you could have a static ThreadLocal where your ThreadLocalData class has all your variables as properties:

class ThreadLocalData
{
    public int GlobalInt { get; set; }
    public string GlobalString { get; set; }
}

class Global
{
    static ThreadLocal _ThreadLocal =
        new ThreadLocal( () => new ThreadLocalData() );

    public static ThreadLocalData ThreadLocal
    {
       get { return _ThreadLocal.Value; }
    }
}

You would then access the properties like this:

int i = Global.ThreadLocal.GlobalInt;

You could add any global variables that are not thread-local as normal properties of the Global class.
