C# Anonymous Types

C# Anonymous types allow us to create an object that has read only properties. Anonymous object is an object that has no explicit type. C# compiler generates type name and is accessible only for the current block of code.

To create anonymous types, we must use new operator with an object initializer.

C# Anonymous Types Example

 using System; namespace CSharpFeatures {     class AnonymousTypesExample     {         public static void Main()         {             // Creating Anonymous Object             var student = new { ID = 101, Name = “Peter”, Email = “peter@example.com”};             // Accessing object properties             Console.WriteLine(student.ID);             Console.WriteLine(student.Name);             Console.WriteLine(student.Email);         }     } } 

Output:

101 Peter [email protected]

We can also use it in query expression to select the records. In the following example, we are selecting students records by creating anonymous type.

 using System; using System.Collections.Generic; using System.Linq; namespace CSharpFeatures {     class Student     {         public int ID { get; set; }         public string Name { get; set; }         public string Email { get; set; }     }      class AnonymousTypesExample     {         public static void Main()         {             List students = new List {                 new  Student{ ID=101, Name=”Rahul”, Email=”rahul@example.com” },                 new  Student{ ID=102, Name=”Peter”, Email=”peter@abc.com” },                 new  Student{ ID=103, Name=”Irfan”, Email=”irfan@example.com” }             };                  var stquery =             from student in students             select new { student.ID, student.Name, student.Email }; // Creating Anonymous Types             foreach (var st in stquery)             {                 Console.WriteLine(“ID = {0}, Name = {1}, Email = {2}”, st.ID, st.Name, st.Email);             }         }     } } 

Output:

ID = 101, Name = Rahul, Email = [email protected] ID = 102, Name = Peter, Email = [email protected] ID = 103, Name = Irfan, Email = [email protected]
