In this tutorial, we will see how to pass/get data to/from a thread in C#. To pass data into the thread we will simply pass it as an input parameter to the method that is being started as a new thread. To get the data from the thread a delegate callback method will be used. First, we will make a regular method that takes in an input parameter. Then we will make a delegate and make it point to this method. Finally, the delegate will be passed as an input parameter to the method that is being started as a new thread. When the child thread is done executing it will call the callback method that is located in the main thread and pass it the result as an input parameter. This is how we will be able to get the result from the child thread back into the main one.

In this tutorial, we will take a look at threads in C#. To explain what a thread is let’s first start off with the explanation of what a process is. A process is an instance of your application. The OS will assign it a chunk of virtual memory, execution context(program counter, registers, PID, …) and resource handles.

In this tutorial, we will take a look at events in C#. A class(subscriber class) can subscribe to an event of another class(publisher class). The publisher class notifies the subscriber class every time the event occurs. This works by using delegates. The subscriber will pass its delegate to the publisher class to “make a subscription” to its event. When the event occurs the publisher will call the delegate(callback method) that was provided to it by the subscriber when it “subscribed” to the event. This is how (for example button press event) events work in .NET. This principle of operation is also called the observer pattern.

In this tutorial, we will take a look at delagates in C#. A delegate is a pointer to a method(basically an indirect call to the method). Delegates can be passed as input parameters to other methods. A benefit of this is that it provides flexibility. Such a method can then use the passed in delegate to call another method(callback method). This is actually the way events work.
