The method below is what I want to be done in that thread:
public void Startup(int port,string path)
{
Run(path);
CRCCheck2();
CRCCheck1();
InitializeCodeCave((ushort)port);
}
I tried what I could find googling,but nothing worked
public void Test(int port,string path)
{
Thread t = new Thread(Startup(port,path));
}
public void TestA(int port,string path)
{
Thread t = new Thread(Startup);
t.Start (port,path);
}
Both don't compile,how to do that?

The method that you want to run must be a ThreadStart
Delegate. Please consult the Thread
documentation on MSDN. Note that you can sort of create your two-parameter start with a closure. Something like:
var t = new Thread(() => Startup(port, path));
Note that you may want to revisit your method accessibility. If I saw a class starting a thread on its own public method in this manner, I'd be a little surprised.
Your example fails because Thread methods take either one or zero arguments. To create a thread without passing arguments, your code looks like this:
void Start()
{
// do stuff
}
void Test()
{
new Thread(new ThreadStart(Start)).Start();
}
If you want to pass data to the thread, you need to encapsulate your data into a single object, whether that is a custom class of your own design, or a dictionary object or something else. You then need to use the ParameterizedThreadStart delegate, like so:
void Start(object data)
{
MyClass myData = (MyClass)myData;
// do stuff
}
void Test(MyClass data)
{
new Thread(new ParameterizedThreadStart(Start)).Start(data);
}
Update The currently suggested way to start a Task is simply using Task.Run()
Task.Run(() => foo());
Note that this method is described as the best way to start a task see here

I like the Task Factory from System.Threading.Tasks. You can do something like this:
Task.Factory.StartNew(() =>
{
// Whatever code you want in your thread
});
Note that the task factory gives you additional convenience options like ContinueWith:
Task.Factory.StartNew(() => {}).ContinueWith((result) =>
{
// Whatever code should be executed after the newly started thread.
});
Also note that a task is a slightly different concept than threads. They nicely fit with the async/await keywords, see here.
public class ThreadParameter
{
public int Port { get; set; }
public string Path { get; set; }
}
Thread t = new Thread(new ParameterizedThreadStart(Startup));
t.Start(new ThreadParameter() { Port = port, Path = path});
Create an object with the port and path objects and pass it to the Startup method.
