如何使用 XmlSerializer 將物件還原序列化

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。

還原序列化物件

1. 使用要還原序列化的物件型別，建構 XmlSerializer。

2. 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 Using
   

   // 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);
