How to pass multiple parameters to a parameterized thread.
In.NET 2.0, there is a new delegate, ParameterizedThreadStart, which takes a parameter of type object. You can create a thread using an instance of this delegate instead of just ThreadStart, and a new overload to Thread.Start allows you to specify the value to be passed to the new thread.
Passing Parameters to Threads. Often when you start a thread, you want to give it some parameters - usually some data it has to process, a queue to wait on, etc. The ThreadStart delegate doesn't take any parameters, so the information has to be stored somewhere else if you are going to create a new thread yourself. Typically, this means.
You may get numbers of complex reasons of using delegates on different site. I am not going to put a complex paragraph here. In simple word delegates contains the reference to several methods and call them when needed. So, you create numbers of methods as you need and attach it to delegates. At runtime, an event gets fired and delegates.
Instead of adding all your parameters in one go, use an object. Now before we go any further, notice I'm using the term 'Object' here. To me this will generally mean a class, some people however prefer to use structs, some prefer generic objects, it really doesn't matter what you use, the principle is still the same, and I have no desire to get into a religious war over which type is best.
This component executes code on a separate thread.It uses events to communicate with main user interface thread. Task Parallel Library (TPL) These tools let you easily run multiple methods in different threads or run multiple instances of the same method with different parameters. The task class let you create and run threads.
Re-Throwing Exceptions When you trap an exception in a catch block, the exception is considered to have been processed and code execution continues normally. Sometimes you will want to catch the exception but still have it thrown to be caught again.
