瞭解如何使用 JsonSerializer 類別、JsonSerializerOptions 類別和數據傳輸物件，串行化和還原串行化 JavaScript 物件表示法 （JSON） 字串。
當您還原序列化物件時，傳輸格式決定您會建立資料流或檔案物件。 決定傳輸格式後，您可視需要呼叫 Serialize 或 Deserialize 方法。
使用要還原序列化的物件型別，建構 XmlSerializer。
呼叫 Deserialize 方法以產生物件的複本。 在還原序列化時，您必須將所傳回物件轉換成原始的類型 (如下面的範例所示)，其會從檔案將物件還原序列化 (雖然其也能從串流還原序列化)。
' Construct an instance of the XmlSerializer with the type ' of object that is being deserialized. Dim mySerializer As New XmlSerializer(GetType(MySerializableClass)) ' To read the file, create a FileStream. Using myFileStream As New FileStream("myFileName.xml", FileMode.Open) ' Call the Deserialize method and cast to the object type. Dim myObject = CType( _ mySerializer.Deserialize(myFileStream), MySerializableClass) End UsingC#// Construct an instance of the XmlSerializer with the type // of object that is being deserialized. var mySerializer = new XmlSerializer(typeof(MySerializableClass)); // To read the file, create a FileStream. using var myFileStream = new FileStream("myFileName.xml", FileMode.Open); // Call the Deserialize method and cast to the object type. var myObject = (MySerializableClass)mySerializer.Deserialize(myFileStream);
