Auto-Property Initializers for Read-Only Properties in C# 6.0

Posted by AbundantCode

In the earlier version of C# , if you want a read-only property , you would end up having a backing field which is initialized in the constructor.

public class Employee
{

        private readonly DateTime _CreatedDate;
        public DateTime CreatedDate
        {
            get
            {
                return _CreatedDate;
            }
        }
        public Employee()
        {
            _CreatedDate = DateTime.Now;
        }
}

In C# 6.0 , the auto-implemented properties can be used to implement read-only property using the auto-property initializer as shown below.
