C# Default values for getter-only properties

This feature allows us to set default values for the getters. The getter-only property is read-only property. We can’t set a new value to this property.

Compiler reports an error: cannot be assigned at compile time, if we assign value explicitly.

C# Default value for getter-only property Example 1

 using System; namespace CSharpFeatures {     class Student     {         public string Name { get; } = “Rahul kumar”;         public string Email { get; } = “rahul@abc.com”;     }     public class PropertyInitializer     {         public static void Main(string[] args)         {             Student student = new Student();             Console.WriteLine(student.Name);             Console.WriteLine(student.Email);         }     } } 

Output

Rahul kumar [email protected]

Let’s see an example, what happen if we assign value explicitly.

C# Default value for getter-only property Example 2

 using System; namespace CSharpFeatures {     class Student     {         public string Name { get; } = “Rahul kumar”;         public string Email { get; } = “rahul@abc.com”;     }     public class PropertyInitializer     {         public static void Main(string[] args)         {             Student student = new Student();             Console.WriteLine(student.Name);             Console.WriteLine(student.Email);             student.Name = “john”;             Console.WriteLine(student.Name);         }     } } 

Output

error CS0200: Property or indexer 'Student.Name' cannot be assigned to -- it is read only
