How to run Multiple Process in C# [closed]

Answer 1

The easiest option is to use a Task class. Msdn nails it, just copying (with minor edits) the relevant bit here

Action action1 = () =>
{
    // your code here
};

Action action2 = () =>
{
    // your code here
};

Task t1 = new Task(action1);
Task t2 = new Task(action2);

t1.Start();
t2.Start();

In general, to do several things in parallel, you need to use threads. The easiest way to do that is through tasks:

Task.Run(() => functionA(argument));
Task.Run(() => functionB(argument));
Task.Run(() => functionC(argument));

However, in your case, all your functions are trying to update the UI, and only the main thread (UI thread) can do that. So it's definitely not a good use case for multithreading.

By reading this, you will figure out that your code will look similar to this:

System.Threading.Tasks.Task.Factory.StartNew(() => functionA("arg"));
System.Threading.Tasks.Task.Factory.StartNew(() => functionB("arg"));
System.Threading.Tasks.Task.Factory.StartNew(() => functionC("arg"));
