C# Pair类（开发人员如何使用）

// Tuple declaration
var person = (name: "John", age: 30);

// Accessing tuple elements using named properties
Console.WriteLine($"Name: {person.name}, Age: {person.age}");

// Tuple deconstruction
var (name, age) = person;
Console.WriteLine($"Name: {name}, Age: {age}");

' Tuple declaration
Dim person = (name:= "John", age:= 30)

' Accessing tuple elements using named properties
Console.WriteLine($"Name: {person.name}, Age: {person.age}")

' Tuple deconstruction
'INSTANT VB TODO TASK: VB has no equivalent to C# deconstruction declarations:
var(name, age) = person
Console.WriteLine($"Name: {name}, Age: {age}")
