==Get/set a property using a PropertyInfo==

<source lang="csharp">using System;
using System.Reflection;
using System.Windows.Forms;
public class Class1
{
static void Main( string[] args )
{
Type type = typeof(MyClass);
object o = Activator.CreateInstance(type);

//get and set a property using a PropertyInfo
PropertyInfo property = type.GetProperty("Text");
property.SetValue(o, "www.softconcepts.ru", null);
string text = (string)property.GetValue(o, null);

Console.WriteLine(text);

EventInfo eventInfo = type.GetEvent("Changed");
eventInfo.AddEventHandler(o, new EventHandler(Class1.OnChanged));
((MyClass)o).Text = "New Value";
}
private static void OnChanged(object sender , System.EventArgs e)
{
Console.WriteLine(((MyClass)sender).Text);
}
}
public class MyClass
{
private string text;

public string Text
{
get{ return text; }
set
{
text = value;
OnChanged();
}
}

private void OnChanged()
{
if( Changed != null )
Changed(this, System.EventArgs.Empty);
}

public event EventHandler Changed;

using System.Reflection;
public interface IFaceOne
{
void MethodA();
}
public interface IFaceTwo
{
void MethodB();
}
public class MyClass: IFaceOne, IFaceTwo
{
public enum MyNestedEnum{}

public int myIntField;

}
public int MyProp
{

set { myIntField = value; }
}
void IFaceOne.MethodA(){}
void IFaceTwo.MethodB(){}
}
public class MainClass
{
public static void Main(string[] args)
{
MyClass f = new MyClass();
Type t = f.GetType();
PropertyInfo[] pi = t.GetProperties();
foreach(PropertyInfo prop in pi)
Console.WriteLine("Prop: {0}", prop.Name);
}
}</source>
<pre class=codeResult>Prop: MyProp</pre>

==Using Type.GetProperties() to Obtain an Object"s Public Properties==

<source lang="csharp">using System;
