using System.Threading; class ThreadExample { static int slot; static void Main() { slot = Thread.AllocateDataSlot(); Console.WriteLine("Allocated data slot = {0}", slot); Thread t1 = new Thread(new ThreadStart(ThreadMethod)); t1.Start(); Thread t2 = new Thread(new ThreadStart(ThreadMethod)); t2.Start(); Console.ReadLine(); } static void ThreadMethod() { int data = 1; Thread.SetData(slot, data); Console.WriteLine("Thread ID = {0}, data = {1}", Thread.CurrentThread.ManagedThreadId, data); } }In this example, we first allocate a data slot using the AllocateDataSlot method. We then create two new threads and pass them the method ThreadMethod to be executed. In the ThreadMethod, we set the per-thread data using the SetData method and retrieve it using the GetData method. This example demonstrates the usage of the AllocateDataSlot method to allocate a slot for per-thread data. The package library used is the System.Threading package.
