我怎样才能在VB.NET中对JSON进行编码？

Imports System.Text.Json

Module Module1
    Sub Main()
        Dim person As New Person()
        person.Name = "张三"
        person.Age = 25

        Dim jsonOptions As New JsonSerializerOptions()
        jsonOptions.WriteIndented = True

        Dim jsonString As String = JsonSerializer.Serialize(person, jsonOptions)
        Console.WriteLine(jsonString)
    End Sub
End Module

Public Class Person
    Public Property Name As String
    Public Property Age As Integer
End Class

Dim jsonString As String = "{ ""Name"": ""张三"", ""Age"": 25 }"
Dim person As Person = JsonSerializer.Deserialize(Of Person)(jsonString)
Console.WriteLine($"Name: {person.Name}, Age: {person.Age}")
