Object Classification via Positional Patterns

Positional patterns allow you to deconstruct an object and match against its parts. This is highly effective for state-based logic and replaces long if-else chains with readable switch expressions.

snippet.cs

csharp

var result = person switch
{
    ("Admin", true) => "Full Access",
    ("User", true) => "Standard Access",
    (_, false) => "Account Disabled",
    _ => "Unknown Role"
};

Breakdown

("Admin", true) => "Full Access"

Matches if the deconstructed object has the role 'Admin' and is active.

(_, false) => "Account Disabled"

The discard (_) matches any role as long as the second property is false.
