C# 子线程调到主线程运行 主要是修改UI界面

UIHelper 类

        static public class UIHelper
        {
            /// <summary>
            /// Access the GUI thread
            /// </summary>
            /// <param name="control"></param>
            /// <param name="code"></param>
            static public void InvokeOnUIifRequired(Control control, MethodInvoker code)
            {
                if (control.InvokeRequired && control.Visible == true)
                {
                    control.Invoke(code);
                }
                else
                {
                    code.Invoke();
                }

                /*Thread t = new Thread(new ThreadStart(delegate()
                {
                    CrossThread cross = delegate()
                {
                    control.Refresh();
                };
                control.Invoke(cross);
                }));*/
            }
        }

使用：

 UIHelper.InvokeOnUIifRequired(this, delegate
                {
                    TempPictureBox.Image = img;
                });

   public delegate void Delegate_UpdateChannel(int iIndex);//0--15
