Exception Cross-thread

Exception:- Cross-thread operation not valid: Control 'treeView' accessed from a thread other than the thread it was created on.

I have kept treeview, You can replace it with control of your choice

Solution

  if (treeView.InvokeRequired)
                    {
                        this.Invoke((MethodInvoker)delegate()
                        {
                         
                            tn = treeView.SelectedNode;
                          
                        });
                    }
