Looping through Object's properties in C Sharp

Loop to Find All Properties Info of an Object In C#.

Have you ever tried to make a dynamic test page? To build and HTML element contains all the properties of a specific .Net object?

Well, I encountered this problem couple of days ago and while searching Google I barely found good matches.  So I decided that for my sake, and yours, I will simply post a short explanation about how to do it, followed by a quick and simple example of how to loop though object properties in C#.

First I'll provide a short explanation about Reflection:
Reflection enables you to discover an object's properties, methods, events and properties values at run-time.  Reflection can give you a full mapping of an object (well, it's public data).

In order to use reflection, and to loop through the object's properties, we'll first have to import the namespace:
using System.Reflection;

Now, lets say I have an object called User and this object has 2 public properties:

1. UserID.
2. Name.

My code will look something like this:

int testID = 123456;

User usr = new User(testID); // this is constructor to get user by ID

StringBuilder sb = new StringBuilder();

PropertyInfo[] properties = user.GetType().GetProperties();

foreach (PropertyInfo pi in properties)

{

    sb.Append(

        string.Format("Name: {0} | Value: {1}", 

                pi.Name, 

                pi.GetValue(user, null)

            )

    );

}

divResults.InnerText = sb.ToString();

This little piece of code will fill your HTML element with the properties names and values.
