Function overloading allows multiple function with the same name. But the signatures of each function should vary. 

For example

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
 
namespace ConsoleApplication1
{
    classProgram
    {
        staticvoid Main(string[] args)
        {
                             }
    }
 
    publicclassAccount
    {
        publicvoid Account()
        { 
        }
        publicvoid Account(String Name)
        { 
        }
    }
 
}
