C# Eval function?

Question

Hi there I want to access an object property dynamically. Basi idea is I got a string as oClient.Name where oClient is an object of type Client and name is the property. How can I get a value of this property at run time? It is something similar to Eval function we have in Jscript. Any option for C#.net developer ? Cheers Ricky

In C# you can use reflection to both create an object dynamically and to access its properties. Here's a quick example: using System; using System.Reflection; class Program { static void Main() { Type t = typeof(Client); object oClient = Activator.CreateInstance(t new object[]{Ricky}); BindingFlags bf = BindingFlags.Public | BindingFlags.Instance | BindingFlags.GetProperty; string name = (string)t.InvokeMember(Name bf nulloClientnull); Console.WriteLine(The name of the client is {0} name); Console.ReadLine(); } } class Client { private string name; public string Name { get{ return name;} set{ name = value;} } public Client(string name) { this.name = name; } } As you can see the code to do this is rather tedious though it should get better in C# 4.0 where some special syntax to deal with 'dynamic lookup' is planned :)
