C# Error CS0442 – ‘Property’: abstract properties cannot have private accessors

C# Compiler Error

CS0442 – ‘Property’: abstract properties cannot have private accessors

Reason for the Error

You’ll get this error in your C# code when you try to use the private access modifier on an accessor of a abstract property.

For example, let’s try to compile the below C# code snippet.

using System;
namespace DeveloperPublishNamespace
{
    public abstract class Employee
    {
        public abstract int Id
        {
            get;
            private set; 
        }
    }
    class Program
    {      
        static void Main(string[] args)
        {
            Console.WriteLine("Hello World!");
        }
    }
}

You’ll receive the error code CS0442 when you build the above C# code because you have declared an abstract property “Id” in the Employee class but you have modified the access modifier of the setter to private.

Solution

You can fix this error in your C# program by either making the accessor non-abstract or using a different access modifier for the property.

using System;
namespace DeveloperPublishNamespace
{
    public abstract class Employee
    {
        public abstract int Id
        {
            get;
            set; 
        }
    }
    class Program
    {      
        static void Main(string[] args)
        {
            Console.WriteLine("Hello World!");
        }
    }
}
