Does C# have a “ThreadLocal” analog (for data members) to the “ThreadStatic” attribute?

Question

I\'ve found the \"ThreadStatic\" attribute to be extremely useful recently, but makes me now want a \"ThreadLocal\" type attribute that lets me hav

I'm not sure how you're spawning your threads in the first place, but there are ways to give each thread its own thread-local storage, without using hackish workarounds like the code you posted in your question.

public void SpawnSomeThreads(int threads)
{
    for (int i = 0; i < threads; i++)
    {
        Thread t = new Thread(WorkerThread);

        WorkerThreadContext context = new WorkerThreadContext
        {
            // whatever data the thread needs passed into it
        };

        t.Start(context);
    }
}

private class WorkerThreadContext
{
    public string Data { get; set; }
    public int OtherData { get; set; }
}

private void WorkerThread(object parameter)
{
    WorkerThreadContext context = (WorkerThreadContext) parameter;

    // do work here
}

This obviously ignores waiting on the threads to finish their work, making sure accesses to any shared state is thread-safe across all the worker threads, but you get the idea.
