Introduction For methods having numerous arguments we tend to get confused. And this is also pain for others while reviewing the code. C# 4.0 gives us an opportunity to pass parameters with name. How it works, let’s check it. Suppose you have a method like below, C# Code:
public static class TestClass { public static void ParamMethod(string Name, double Salary, string Department, int Age = 30) { Console.WriteLine("Name = {0}", Name); Console.WriteLine("Age = {0}", Age); Console.WriteLine("Salary = {0}", Salary); Console.WriteLine("Department = {0}", Department); } } Now the calling would look like, TestClass.ParamMethod(Name:"Amal", Salary:1000.00, Department:"Software",Age:31); You can alter the sequence of the parameters too, TestClass.ParamMethod("Tupur", 2000.00, Department: "IT", Age: 26); No compiler overhead is associated with it. Rule, Non-optional parameters has to be specified either sequentially or by name. Thank you Amal
