C# Error CS0516 – Constructor ‘constructor’ can not call itself

C# Compiler Error

CS0516 – Constructor ‘constructor’ can not call itself

Reason for the Error

You’ll get this error in your C# code when you try to call the constructor recursively.

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

using System;
namespace DeveloperPublishNamespace
{
    public class BaseClass
    {
        public BaseClass() : this()
        {

        }
    }
    class Program
    {    
        static void Main(string[] args)
        {
            Console.WriteLine("No Error");
        }
    }
}

using System;

namespace DeveloperPublishNamespace

{

    public class BaseClass

    {

        public BaseClass() : this()

        {

​

        }

    }

    class Program

    {    

        static void Main(string[] args)

        {

            Console.WriteLine("No Error");

        }

    }

}

You’ll receive the error code CS0516 because the class BaseClass has a constructor and we are attempting to call the constructor itself using the this() operator.

Solution

To fix this error, avoid calling the constructor recursively. Remove the this() from the above code snippet to fix this error.
