What is the use of threadstart class and thread class in c#.net?

Question

Multi Threading

Sachin Singh · Answer

At first ThreadStart is not a class , it is a delegate , in c# delegates are types so it can be used as a method parameter. The second speciality of delegate is , it can point to any method of same signature. In c# the orginal Thread class accepts ThreadStart delegate as parameter means there is one overloaded version of Thread class constructor which accepts a ThreadStart delegate as parameter. now as it is a delegate , it can point any method of same signature , that is the reason we are able to pass any method inside thread constructor while creating an instance of it. Microsoft developers are very clever wherever they need to delegate the logic to the the caller of the class they have created a delegate and used as parameter so that we could create our own method and could be able to pass them inside method/extension method/constructor as parameter. Linq extension methods are full of delegates that is the reason we are able to use lambda expressions as parameters as lambda expressions are nothing but shorthand way of creating inline delegates (delegates pointing to a method inline)

Thread(ThreadStart) Constructor is used to initialize a new instance of a Thread class. This constructor will give ArgumentNullException if the value of the parameter is null. Syntax: public Thread(ThreadStart start); Here, ThreadStart is a delegate that represents a method to be invoked when this thread begins executing. Thread class In C#, a multi-threading system is built upon the Thread class, which encapsulates the execution of threads. This class contains several methods and properties which helps in managing and creating threads and this class is defined under System.Threading namespace. Characteristics of Thread class: Thread class is used to create threads. With the help of the Thread class, you can create a foreground and background thread. Thread class allows you to set the priority of a thread. It also provides you the current state of a thread. It provides the reference of the currently executing thread. It is a sealed class, so it cannot be inherited.

The difference between new Thread(SomeMethod) and new Thread(new ThreadStart(SomeMethod)) is purely syntactical: The C# compiler generates the same code for these; the former version is an abbreviation of the latter.
