Extract common properties of a class .NET Framework I have more classes with several common properties. e.g. class A { string Class_A_Prop1{get; set;} string Class_A_Prop2{get; set;} string CommonProp1{get; set;} / / common to all classes string CommonProp2{get; set;} } class B { string Class_B_Prop1{get; set;} string Class_B_Prop2{get; set;} string CommonProp1{get; set;} / / common to CommonProp1; string p2 = entity.CommonProp2; Console.WriteLine("{0} {1}", p1, p2); } keep in mind that class A & B are generated by a external tool and I do not want to alter inheritance and interfaces is this possible in C# using generics or anonymous types?

If this was A & B implement a common interface: interface IFoo {. . .} / / common members partial class A : IFoo {} partial class B : IFoo {} And let implicit interface implementation deal with the rest (assuming the properties etc appreciate your wise answer. In that case, simply specify the interface name as the base-class; for dbml files this is an entry in the xml file. At the command line
