C# Error CS0544 – ‘property override’: cannot override because ‘non-property’ is not a property

C# Compiler Error

CS0544 – ‘property override’: cannot override because ‘non-property’ is not a property

Reason for the Error

You will get this error in your C# code when you attempt to override a non-property member (Eg : field) as property.

For example, let’s compile the below C# program

using System;

namespace DeveloperPublishConsoleCore
{
    public class Employee
    {
        public int id;
    }

    public class Contract : Employee
    {
        // Results in the Error Code CS0544  
        public override int id
        {   
            get
            {
                return 0;
            }
        }
    }

    internal class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("DeveloperPublish Hello World!");
        }
    }
}

You will receive the error code CS0544 because you have a field id in the Employee class and you are attempting to override it as property in the Contract class.

Solution

C# compiler does not allow you to override a ‘non-property’ as property. To fix this error in your C# program, ensure that you override the right type.
