the calling thread cannot access wpf win form c# multi threading

If you receive this error:
The calling thread cannot access this object because a different thread owns it

It is a simple fix to add in some common multi-threading invocation mechanisms.

WPF:

//with delegate declared
public delegate mydelegate;
this.Dispatcher.Invoke(new mydelegate(funcname));
                    this.Dispatcher.Invoke((mydelegate)delegate() { funcname(); });

//does not require delegate declared, i usually prefer this approach but there are situations for either
                    this.Dispatcher.Invoke((Action)delegate() { funcname(); });
                    this.Dispatcher.Invoke((Action)(()=>{ funcname();}));

WinForms:

this.Invoke(funcname, params);
this.BeginInvoke(funcname, params);
