如何将匿名类型变量从使用作用域传播到外部？

void Main()
{
    var anonymousVariable = new { Name = "John", Age = 30 };
    var namedVariable = anonymousVariable;

    Console.WriteLine(namedVariable.Name); // 输出：John
    Console.WriteLine(namedVariable.Age); // 输出：30
}

void Main()
{
    var anonymousVariable = new { Name = "John", Age = 30 };
    ProcessAnonymousVariable(anonymousVariable);
}

void ProcessAnonymousVariable(object anonymousVariable)
{
    var namedVariable = anonymousVariable;

    Console.WriteLine(namedVariable.Name); // 输出：John
    Console.WriteLine(namedVariable.Age); // 输出：30
}

void Main()
{
    var anonymousVariable = new { Name = "John", Age = 30 };

    Action printAnonymousVariable = () =>
    {
        Console.WriteLine(anonymousVariable.Name); // 输出：John
        Console.WriteLine(anonymousVariable.Age); // 输出：30
    };

    printAnonymousVariable();
}
