C# Named Arguments

Named arguments in C# allow you to specify the parameter name when calling a method. This improves readability and lets you change the order of arguments safely.

static void Register(string username, string role = "User", bool active = true)
{
Console.WriteLine($"{username}, {role}, Active: {active}");
}



Register("Vipul");
Register("Vipul", active: false);
Register(username: "Vipul", role: "Admin");

static void Register(string username, string role = "User", bool active = true)

{

Console.WriteLine($"{username}, {role}, Active: {active}");

}

🔹 Named Arguments Improve Readability

✔ Easy to understand and maintain.

🔹 Named Arguments with Constructors

🔹 Common Mistakes

❌ Wrong parameter name
❌ Positional arguments after named

🔹 Summary

✔ Named arguments specify parameter names
