multithreading - C# threading - resetThread is a 'variable' but is used like a 'method' -

i'm trying create thread reset button colours in application i'm writing, whenever try create thread object, error 'resetthread 'variable' used 'method'. code i'm using create thread object:

system.threading.thread resetthread = new system.threading.thread(new system.threading.threadstart(resetthread)); 

and code thread:

public void resetthread() {     while (true)     {         optionone.backcolor = default(color);         optiontwo.backcolor = default(color);         optionthree.backcolor = default(color);         system.threading.thread.sleep(1000);     } } 

how go fixing this? in advance. have googled no avail.

call thread different method - call method reset() instance. can't have method , field same name @ class scope.
