如何使用 XmlSerializer 反序列化对象

当您反序列化对象时，传输格式确定您将创建流还是文件对象。 确定了传输格式之后，就可以根据需要调用 Serialize 或 Deserialize 方法。

反序列化对象

1. 使用要反序列化的对象的类型构造 XmlSerializer。

2. 调用 Deserialize 方法以生成该对象的副本。 在反序列化时，必须将返回的对象强制转换为原始对象的类型，如以下示例所示，该示例从文件反序列化该对象（尽管也可以从流反序列化该对象）。

   ' 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);
