  1. PORemove redundant C# code without using interface
    text
    copied!<p>Please consider two restrictions -</p> <ol> <li>Can't move MyProperty to interface or abstract class.</li> <li>FooEventHandler is a dotnet framework method hence can't change paramter type.</li> </ol> <p>I have MyProperty defined in several classes.</p> <pre><code>class A { public string MyProperty { get; set; } } class B { public string MyProperty { get; set; } } class C { public string MyProperty { get; set; } } </code></pre> <p>Method FooEventHandler updates this property for all parameters it receives.</p> <pre><code>public object FooEventHandler(object obj) { object toReturn = null; if (obj.GetType() == typeof(A)) { (obj as A).MyProperty = "updated"; toReturn = obj; } else if (obj.GetType() == typeof(B)) { (obj as B).MyProperty = "updated"; toReturn = obj; } else if (obj.GetType() == typeof(C)) { (obj as C).MyProperty = "updated"; toReturn = obj; } return toReturn; } </code></pre> <p>And FooEventHandler is called repeatedly like this -</p> <pre><code>static void Main(string[] args) { Program program = new Program(); A objA = new A(); program.FooEventHandler(objA); B objB = new B(); program.FooEventHandler(objB); C objC = new C(); program.FooEventHandler(objC); } </code></pre> <p>Please suggest a way to remove redundant code in Foo, considering above two restrictions in general.</p> <p>To be more precise, I have encountered this issue while using ParameterInspector in WCF. I am trying to modify propery of all the requests intercepted here and had to write Switch Case based on operationName.</p> <p><strong>A, B, C, D</strong> classes as said above are proxies. So don't want to modify them at first place. Since updating service Reference will overwrite my iterface changes.</p> <pre><code>public object BeforeCall(string operationName, object[] inputs){ // update inputs[0] properties } </code></pre> <p>Thank you for your help.</p>
