what is named parameters in c#

Visual Studio 2010 and above give us a facility to specify an argument for a particular parameter by associating the arguments with the parameter's name rather than with the parameter's position in the parameter list.
For example:
    public class Employee
        public Employee()
        { }
        public void emp(string fName, string lName, decimal salary)
        // here your code
        public void Main(string[] args)
           emp(fName: "dilip", lName: "Singh",salary: 10000);
           emp(salary: 10000, fName: "dilip", lName: "Singh");
