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); 
   }

List Properties

<source lang="csharp">using System; using System.Reflection; public interface IFaceOne {

 void MethodA();

} public interface IFaceTwo {

 void MethodB();

} public class MyClass: IFaceOne, IFaceTwo {

 public enum MyNestedEnum{}

} public class MainClass {

 {
   MyClass f = new MyClass();

   PropertyInfo[] pi = t.GetProperties();
   foreach(PropertyInfo prop in pi)
     Console.WriteLine("Prop: {0}",  prop.Name);

Prop: MyProp

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

<source lang="csharp">using System; class MainClass {

 static void Main()
 {
   DateTime dateTime = new DateTime();
   
   Type type = dateTime.GetType();
   foreach (
       System.Reflection.PropertyInfo property in
           type.GetProperties())
   {
       System.Console.WriteLine(property.Name);
   }
 }
