typeof

[This is preliminary documentation and subject to change]

The typeof operator is used to obtain the System.Type object for a type. A typeof expression takes the form:

typeof(type)

where:

type
The type for which the System.Type object is obtained.

Remarks

The typeof operator cannot be overloaded.

To obtain the run-time type of an expression, you can use the NGWS Framework method GetType.

Example

using System;
using System.Reflection;

public class MyClass {
   public int intI;
   public void MyMeth() {}

   public static void Main() {
      Type t = typeof(MyClass);

      // alternatively, you could use
      // MyClass t1 = new MyClass();
      // Type t = t1.GetType();   
      
      MethodInfo[] x = t.GetMethods();      
      foreach (MethodInfo xtemp in x) {
         Console.WriteLine(xtemp.ToString());
      }

      Console.WriteLine();

      MemberInfo[] x2 = t.GetMembers();
      foreach (MemberInfo xtemp2 in x2) {
         Console.WriteLine(xtemp2.ToString());
      }      
   }
}

Output

Int32 GetHashCode ()
Boolean Equals (System.Object)
System.String ToString ()
Void MyMeth ()
Void Main ()
System.Type GetType ()

Int32 intI
Int32 GetHashCode ()
Boolean Equals (System.Object)
System.String ToString ()
Void MyMeth ()
Void Main ()
System.Type GetType ()
Void .ctor ()

Example

// Using GetType method
using System;
class GetTypeTest {
   public static void Main() {
      int radius = 3;
      Console.WriteLine("Area = {0} ", radius*radius*Math.PI);
      Console.WriteLine("The type is {0}", 
               (radius*radius*Math.PI).GetType());
   }
}

Output

Area = 28.274333882308138
The type is Double
