Using ThreadPools - #Macklemore - Jun 24, 2011

To begin threadpools acts like a static object so if you were to use it you would just go like

PHP Code 


<?php 
ThreadPool.(method) 

Now the most common method you will use with a ThreadPool is the method to add a method which it will then create a thread to execute it.
This method is called as such

PHP Code 


<?php 
public void somemethod(Object ThreadName)
{Console.WriteLine(ThreadName.ToString());}

string threadname = "MyThread";
ThreadPool.QueueUserWorkItem(somemethod,threadname); 

The ThreadPool only allows for methods with an object parameter and if you really don't need it then just don't use it.

Now what if you had a method with parameters, well it takes a little bit of extra coding but it is plausible. Before i show the code the basis is just creating a class and having all your parameters in the constructor then having the method within that class which will draw its variables through the newly declared ones in the constructor;

PHP Code 


<?php 
class threadpoolclass{
private string info_, info_2, info_3;
  public threadpoolclass(string info,string info2,string info3){
  info_ = info;
  info_2 = info2;
  info_3 = info3;
  }
    public methodwithmultipleparameters(Object Name){
  Console.WriteLine(info_+info_2+info_3 +Name.ToString());
  }
}
class main{
  public main(){
  threadpoolclass tpc = new threadpoolclass("this ","is a "," example");
  string name = "workerthread";
    ThreadPool.QueueUserWorkItem(tpc.methodwithmultipleparameters,name);
  }
} 

That the basics of the ThreadPool class and now i just want to show one example of creating multiple threads.

PHP Code 


<?php 
public void countfrom(Object start){
int start_ = (int)start;
for(int iii = 100;start_<=iii;start_++){
  Console.WriteLine(start_);
    }
}
public void startmethods(){
    for(int ii = 0;ii<=25;ii++){
  ThreadPool.QueueUserWorkItem(countfrom,ii);
    }
} 

So all this example is doing is creating 25 threads with all a different start number and they all count up to 100.

thanks for reading and the last thing i want to say is remember to

PHP Code 


<?php 
using System.Threading; 

while working with a ThreadPool.
