.net - C# constructor with json style arguments -


i have been watching pluralsight video on generics in c# (so doesnt cover code specifically) , example code has constructor set out in manner i've never seen before:

public circularbuffer()     : this(capacity: 10) { }  public circularbuffer(int capacity) {   // other code here }

the constructor called so

var cb = new circularbuffer(capacity: 3);

what notation , when introduced? there special considerations when using it? there , benefit have on existing solutions?

it named "named arguments" , introduced .net 4.0.

it has been introduced optional arguments , relevant in scenario. named argument syntax, can provide values some of optional arguments without need supply values others.

no special considerations necessary, strictly syntactic sugar used compiler.
