Use Of C# TypeOf Operator

In C#, types are inherited from the System.Type. The C# typeof operator gets the System.Type of a type. This code sample shows the use case of typeof operator using C#.

 

 

The typeof operator syntax,

  1. System.Type type = 

    typeof

    (type);    

     

The following code sample uses the typeof operator to get the type of various types.

  1. Type tp = 

    typeof

    (

    int

    );    

  2. Console.WriteLine($

    "typeof {tp}"

    );    

  3. Console.WriteLine(

    typeof

    (String));    

  4. Console.WriteLine(

    typeof

    (Double));   

The GetType() method is used to get the Type of an object or expression at runtime.

  1.   

  2. string name = 

    "Mahesh Chand"

    ;    

  3. Type namenameType = name.GetType();    

  4. Console.WriteLine(nameType);    

You can also get a type of a class (object), its methods, properties, and other members.

 

The following code snippet returns a type of the Author object. 

  1.   

  2. Console.WriteLine(

    typeof

    (Author));    

Complete code sample,

  1. using System;    

  2.     

  3. namespace typeofOperatorSample    

  4. {    

  5.     

    class

     Program    

  6.     {    

  7.         

    static

     

    void

     Main(string[] args)    

  8.         {    

  9.             Type tp = 

    typeof

    (

    int

    );    

  10.             Console.WriteLine($

    "typeof {tp}"

    );    

  11.             Console.WriteLine(

    typeof

    (String));    

  12.             Console.WriteLine(

    typeof

    (Double));    

  13.     

  14.             

      

  15.             string name = 

    "Mahesh Chand"

    ;    

  16.             Type namenameType = name.GetType();    

  17.             Console.WriteLine(nameType);    

  18.     

  19.             

      

  20.             Console.WriteLine(

    typeof

    (Author));    

  21.     

  22.             Console.ReadKey();    

  23.         }    

  24.     }    

  25.     

  26.     

    public

     

    class

     Author    

  27.     {    

  28.         

    public

     Author() { }    

  29.     }    

  30. }   

The output of the above code generates the following output.
