C# Language Partial methods


Example

Partial method consists of the definition in one partial class declaration (as a common scenario - in the auto-generated one) and the implementation in another partial class declaration.

using System;

namespace PartialClassAndMethods
{
    public partial class PartialClass // Auto-generated
    {
        partial void PartialMethod();
    }

    public partial class PartialClass // Human-written
    {
        public void PartialMethod()
        {
            Console.WriteLine("Partial method called.");
        }
    }

    class Program
    {
        static void Main(string[] args)
        {
            PartialClass partial = new PartialClass();
            partial.PartialMethod(); // outputs "Partial method called."
        }
    }
}
