I'm newbie in OO programing and C#, and I would need some help.
I have several methods that could possibly be called upon a PropertyChanged event from a class member. A collection of that class is created based with data coming from a text file
I would like that the method to be called is also read from the text file like any other data (as string then).
How could I instanciate the event handlder and register to that event without giving the method as argument, but the method name instead, like:
var handler = new PropertyChangedEventHandler(MyHandler)
myData.PropertyChanged += (PropertyChangedEventHandler)handler;
I would like to achieve something like:
string str = "MyHandler";
var handler = new PropertyChangedEventHandler(str)
myData.PropertyChanged += (PropertyChangedEventHandler)str;`
I know that this is not working, but I don't know where to look to find a solution to this.
Thanks.
You could try using reflection to find the method and dynamically assign it to the delegate, something like:
public void AssignPropertyChangedMethod(string methodName)
{
var methodInfo = this.GetType().GetMethod(methodName, BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Instance);
var handler = Delegate.CreateDelegate(typeof(PropertyChangedEventHandler), this, methodInfo);
myData.PropertyChanged += (PropertyChangedEventHandler)handler;
}
I haven't tested it myself so I am not sure it will work but maybe it will get you in the right direction.
