I am stuck with a weird problem
Let me show you my code
private static void OnMyCustomPropertyChanged(Object sender, EventArgs e)
{
PropertyInfo propInfo = e.GetType().GetProperty("PropName");
String propName = propInfo.GetValue(?,?).ToString();
}
The problem is, what do I mention in place of the two question marks, the second parameter is null as far as I know since it is not an indexed property. When I use propInfo/propInfo.GetType().GetProperty("PropName")/sender, in place of the first "?", I am getting an exception - TargetException was unhandled by user code.
I was wondering if anyone could help me out with this along with an explanation if possible. I would like to understand where I am making the mistake.
The first parameter must be the instance you want to get the value from.
In your example, you should pass e
as parameter, because you're getting a property of the e
object.
That being said, I suspect you want the property of the sender
instance instead:
PropertyInfo propInfo = sender.GetType().GetProperty("PropName");
String propName = propInfo.GetValue(sender, null).ToString();
