C # multithreaded programming, parameters, accepting return values

Today will be multi-threaded knowledge has reviewed the next, summed up a few points:

Create a new thread (no parameters, no return value)

1. Thread th = new Thread (new ThreadStart (Printname));
3. public void Printname () //function
4. {
5. //function Body
6. }

It is important to note that the functions in ThreadStart are not return values and parameters.

Then there are parameters, which are as follows:

1. Thread th = new Thread (new Parameterizedthreadstart (Printname));
2. Public void Printname (string name) //function
3. {
4. //function Body
5. }
   

If you encounter and need a return value, and you need parameters, you can consider using async:

But we need to declare a commission.

2. Public Delegate string Methodcaller (string name); Define an agent
4. Methodcaller mc = New Methodcaller (GetName);
6. String name = "My name"; Input parameters
8. IAsyncResult result = MC. BeginInvoke (name,null, null);
10. String myname = mc. EndInvoke (result); //To receive return values
14. Public string GetName (string name) //function
16. {
18. return name;
20. }

Note here that the generation of new threads in this way is running in the background (background), with the priority being normal
