                             xmlString = UTF8ByteArrayToString(memoryStream.ToArray());返回xmlString;
           }

我编写的上面的代码获得了我在顶部给出的xml输出.当我尝试序列化该类时，我就得到了.什么时候XmlSerializer xs =新的XmlSerializer(typeof(T));该行执行然后发生异常.错误是- 错误，反映了类型'XML2List.OpenShipments'."

我无法检测到为什么在xml序列化时发生错误.
事件我不确定我编写类的方式，该类将正确生成我在顶部显示的所需xml.

所以请有人告诉我如何解决错误并在序列化后获取xml.
还告诉我，在序列化之后，我将以编写代码的方式获得所需的xml输出.

请详细讨论.

i want to get xml after serialization as follows

    <?xml version="1.0" encoding="windows-1252"?>

The above code i wrote to get the xml output which i gave at the top. when i am trying to serialize the class then i am getting. when  XmlSerializer xs = new XmlSerializer(typeof(T)); the line execute then exception occur. the error is -- "There was an error reflecting type 'XML2List.OpenShipments'."

i am not being able to detect why the error occur at the time of xml serialization.
event i am not sure the way i wrote the class that will right to generate my desired xml which i have shown at the top.

so please some one tell me how to fix the error and get the xml after serialization.
also tell me will i get my desired xml output after the serialization the way i wrote the code.

please discuss in detail.

推荐答案

使用可序列化的类属性.例如:

Use Serializable attribute for the classes. Ex:

[Serializable]
  public class Test  {

  }

谢谢
