Get value from custom attribute-decorated property?

Question

I\'ve written a custom attribute that I use on certain members of a class:

public class Dummy
{
    [MyAttribute]
    public string Foo { get; set; }

    [MyAtt

Your need to pass object itself to GetValue, not a property object:

var value = prop.GetValue(o, null);

And one more thing - you should use not .First(), but .FirstOrDefault(), because your code will throw an exception, if some property does not contains any attributes:

object attr = (from row in propattr 
               where row.GetType() == typeof(MyAttribute) 
               select row)
              .FirstOrDefault();
