例外：无法绑定到目标方法，因为其签名或安全透明度与委托类型的签名或安全透明度不兼容

Question

        Type objectType = Application.Current.MainWindow.GetType();
            EventInfo CtrlEventInfo = objectType.GetEvent(strEventName);
            if (CtrlEventInfo == null)
            {
                return;
            }
            Type TypeDelegate = CtrlEventInfo.EventHandlerType;
            MethodInfo methodInfo = typeof(MyPOS.Controls.ActiveAccounts.ViewCtrl).GetMethod(strMethodName, BindingFlags.NonPublic | BindingFlags.Instance);
            Delegate DelHandler = Delegate.CreateDelegate(TypeDelegate, this, methodInfo);
            CtrlEventInfo.AddEventHandler(Application.Current.MainWindow, DelHandler);

无法绑定到目标方法，因为其签名或安全透明度与委托类型的方法不兼容

被抛出

Delegate DelHandler = Delegate.CreateDelegate(TypeDelegate, this, methodInfo);

Answer 1

我认为您需要将代码更改为

 MyPOS.Controls.ActiveAccounts.ViewCtrl obj= new MyPOS.Controls.ActiveAccounts.ViewCtrl();
 Delegate DelHandler = Delegate.CreateDelegate(TypeDelegate, obj, methodInfo);
