Question

Given this definition:

[UniqueId('Ident')] public class MyClass : MyBase {     public int Ident{ get; } } 

What is the best way from the ‘MyBase’ class to get the ‘UniqueId’ attribute, find the matching property name and get the underlying value?

Answer 1

Wouldn’t an abstract method / property in the base-class be more suitable?

public abstract int UniqueId {get;} 

Via attributes, like so:

object GetUniqueId() // or int {     Type type = GetType();     UniqueIdAttribute attrib = null;     foreach(UniqueIdAttribute tmp in          type.GetCustomAttributes(typeof(UniqueIdAttribute), true))     {         attrib = tmp;         break;     }     if (attrib == null) throw new InvalidOperationException();     return type.GetProperty(attrib.PropertyName).GetValue(this, null);     // perhaps cast here...          }
