问题 I'm working on a charge balancing system and thus I need to know the charge of each machine. PerformanceCounter seem the way to go, but creating the first one take between 38 and 60 sec. Each subsequent new Counter or 'NextValue' call is nearly instant however. Here is the code I'm using : [TestClass] public class PerfMon { [TestMethod] public void SimpleCreationTest() { Stopwatch Time = new Stopwatch(); Time.Start(); Debug.WriteLine("Time is : " + Time.ElapsedMilliseconds); // Create

This question already has an answer here: Check whether or not the current thread is the main thread 11 answers I want to know how to call my function on the main thread . How do I make sure my function is called on the main thread ? (this follows a previous question of mine). there any rule I can follow to be sure that my app executes my own code just in the main thread? Typically you wouldn't need to do anything to ensure this — your list of things is usually enough. Unless you're interacting with some API that happens to spawn a thread and run your code in the background, you'll be running
