No overload for 'LoadModel' matches delegate 'System.Threading.ParameterizedThreadStart'    

Answer 1

Another way to solve your problem that allows your method to still have the type of the parameter that you want is to use a lambda expression like this:

Thread thread = new Thread(() => LoadModel(list));

Where list is the parameter value that you want to pass.

Answer 2

This delegate is defined as

public delegate void ParameterizedThreadStart(object obj)

You have to change your method declaration to match it:

private void LoadModel(object filenames)

and cast filenames to List in the method.

To create and start the thread use

Thread loadingThread = new Thread(LoadModel);
loadingThread.Start(filenames);

Instead of creating your own threads, consider using Tasks or ThreadPool.
