Loop through properties of an object

I just had a need to loop through all the properties of an object and copy the values of the properties to another object of the same type. I just discovered that we can use System.Relection to get this done.

For example two objects sourceObject and destinationObject are objects of class Person.

using System.Reflection;
namespace ExampleOfUsingRefelction
  public class Person
    public int Id {get; set;}
    public string Name {get; set;}

  public class Example
    Person sourceObject = new Person();
    sourceObject.Id = 10;
    sourceObject.Name = "Pramod";

    person destinationObject = new Person();
    //now we use Reflection to assign all property values of the sourceObject to the properties of desObject
    PropertyInfo[] properties = destinationObject.GetType().GetProperties();
    foreach(PropertyInfo pi in properties)
       object value = sourceObject.Gettype().GetProperty(pi.Name).GetValue(sourceObject, null);
       pi.SetValue(destinationObject, value, null);
    // at this point we have assigned values of all properties of source
    // object to the destination object without accessing it by its name
