C# Error CS0273 – The accessibility modifier of the ‘property_accessor’ accessor must be more restrictive than the property or indexer ‘property’

C# Compiler Error

CS0273 – The accessibility modifier of the ‘property_accessor’ accessor must be more restrictive than the property or indexer ‘property’

Reason for the Error

You’ll get this error in your C# code when you have defined the accessibility of a accessor that isn’t less restrictive than the accessor of the property or indexer itself.

For example, lets try to compile the below code snippet.

using System;

namespace DeveloperPubNamespace
{
    public class Employee
    {
        private int _id;

        public int Id
        {
            public set { _id = value; }
            get { return _id; }
        }

    }
    class Program
    {
        public static void Main()
        {
            Console.WriteLine("No Error");
        }
    }
}

You’ll receive the error code CS0273 because you are using the public accessor for the Set accessor of the property Id while the property “Id” itself is still public. The C# compiler expects you to have a restricted accessor in this case.

Solution

You can fix this error in your C# program by decreasing the accessibility of the set accessor (Eg : changing the access modifier to private/internal).

using System;

namespace DeveloperPubNamespace
{
    public class Employee
    {
        private int _id;

        public int Id
        {
            private set { _id = value; }
            get { return _id; }
        }

    }
    class Program
    {
        public static void Main()
        {
            Console.WriteLine("No Error");
        }
    }
}
