Quite new and stuck with "threads"

[gibbonuk]

Hi, im trying to get my head around threads or a way to this?

at the moment i have a method that creates a socket sends a string then waits for a return string and stores in inside a variable.

It worked fine to start with but i nocticed my window would freeze because it is using the same thread whilts its "waiting" the data back from the socket client.

So i then put it inside background worker and got it working ok, but i wanted to also put this into its own class.

And thats where ive lost the plot.

I now have the mothod in a class, so i can simply create an instance with a contructor which is the string to send then theres on procedure thats connect and send.

but i want this to happen in the background then one a string or error returns display it inside a textbox.

What is the correct method for doing this?

i am quite new to C# so please bare with me.

Thanks
Andy

Hey,

From my experience, the basic way a thread works in C# is this.

Using multiple threads will allow the processes to take turns in the processor, making it seem like they are running concurrently. You create a thread, handing it either a ThreadStart or ParameterizedThreadStart method, then start it. The method usually contains an infinite loop.

So,

//Semi Psuedo-code

using System.Threading;

Main(...)
{
	Thread thread = new Thread(new ThreadStart(MethodToRun));
	thread.Start()
}

MethodToRun()
{
	while(true)
	{
		if(ThreadShouldEnd)
			break;
		//things here will wait or be repeated as needed
	}
}

//Likewise, if you need to pass an object to the method, use this

Main(...)
{
	SomeClass x;
	Thread thread = new Thread(new ParameterizedThreadStart(MethodToRun));
	thread.Start(x)
}

MethodToRun(object o)
{
	SomeClass x = (SomeClass)o; //cast object to SomeClass as needed
	while(true)
	{
		if(ThreadShouldEnd)
			break;
		//things here will wait or be repeated as needed
	}
}
