Introduction

All types in C# are represented at runtime with an instance of System.Type.

There are two basic ways to get a System.Type object:

  • Call GetType on the instance.
  • Use the typeof operator on a type name.

GetType is evaluated at runtime.

typeof is evaluated statically at compile time.

System.Type has properties for such things as the type's name, assembly, base type, and so on.

Demo Code

using System;//from  w  w  w  . ja  va  2s  . co m
public class Point { public int X, Y; }
class Test
{
   static void Main()
   {
      Point p = new Point();
      Console.WriteLine (p.GetType().Name);             // Point
      Console.WriteLine (typeof (Point).Name);          // Point
      Console.WriteLine (p.GetType() == typeof(Point)); // True
      Console.WriteLine (p.X.GetType().Name);           // Int32
      Console.WriteLine (p.Y.GetType().FullName);       // System.Int32
   }
}
