Question

I want to create a new thread using parametrized thread in c#.

rulehandler is the object of the class

Thread applyPolicyThread = new Thread(
       new ParameterizedThreadStart(rulehandler.ApplyPolicy));
applyPolicyThread.start(false);

It is giving error that no overload method for apply policy matches delegates system.threading.start

Answer 1

The parameter type for parametrized threads must always be object (see HERE):

public void ApplyPolicy(object param)
{
    bool value = (bool)param;
    //your code
}
