Exception: Cannot bind to the target method because its signature or security transparency is not compatible with that of the delegate type
提问by Brett Steigried-StatFord
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);
Cannot bind to the target method because its signature or security transparency is not compatible with that of the delegate type
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
is thrown in line
排成一排
Delegate DelHandler = Delegate.CreateDelegate(TypeDelegate, this, methodInfo);

I think you need to change your code to
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);
