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);
