Orcas 版 C# 3.0 新特性：對象初始化器

對象初始化器讓編譯器自動生成屬性設值代碼，減少硬編碼行數。.NET 類型高度依賴屬性，傳統初始化需多行賦值：

Person person = new Person();
person.FirstName = "Scott";
person.LastName = "Guthrie";
person.Age = 32;

使用 C# 3.0 對象初始化器可簡化為單行：

Person person = new Person { FirstName = "Scott", LastName = "Guthrie", Age = 32 };

編譯器自動生成對應的屬性 setter 調用，語義保持不變。更強大的是，它支援巢狀複雜屬性初始化。假設 Person 有 Address 類型的 Address 屬性：

Person person = new Person {
    FirstName = "Scott",
    LastName = "Guthrie",
    Age = 32,
    Address = new Address {
        Street = "One Microsoft Way",
        City = "Redmond",
        State = "WA",
        Zip = 98052
    }
};

這種聲明式風格讓對象圖構建更直觀，減少樣板代碼，提升可維護性。
