怎么用WebService传输XML文件

Question

RT 还有XmlWriter writer = null;
            try
            {
                //创建一个XMLSerializer对象
                XmlSerializer serializer = new XmlSerializer(fbs.GetType());
                //将XMLWriter对象赋值为XMLTextWriter对象
                writer = new XmlTextWriter(Response.OutputStream, System.Text.Encoding.UTF8);
                //调用序列化方法                serializer.Serialize(writer, fbs);
            }
            finally
            {
                if (writer != null)
                {
                    writer.Close();
                }
            }
Response 在webservice中不能用 为什么 

Answer 1

webservice的基类没有Response 属性，因此没法用。

Answer 2

你不需要自己序列化成xml返回Object（必须是可序列化的）。.net framework会自动帮你序列化。非要自己序列化，可以返回string.

Answer 4

看看是否可以通过httpcontext获取response

Answer 5

[WebMethod]
        public string  xxx() 
        {
            IList<FBook> fbs = FBookManager.GetFBookAll();            XmlWriter writer = null;
            try
            {
                //创建一个XMLSerializer对象
                XmlSerializer serializer = new XmlSerializer(fbs.GetType());
                //将XMLWriter对象赋值为XMLTextWriter对象
                writer = new XmlTextWriter(Response.OutputStream, System.Text.Encoding.UTF8);
                //调用序列化方法                serializer.Serialize(writer, fbs);
            }
            finally
            {
                if (writer != null)
                {
                    writer.Close();
                }
            }
        }这个行不通  大哥 能说详细点么 

Answer 6

参考:XmlSerializer xmlSerializer = new XmlSerializer(typeof(Person));StringWriter stringWriter = new StringWriter();xmlSerializer.Serialize(stringWriter, p1);string serializedXML = stringWriter.ToString();返回string就可以了

Answer 7

报这个错误怎么解决呢生成 XML 文档时出错。 ---> System.InvalidOperationException: 不应是类型 System.IO.StringWriter。使用 XmlInclude 或 SoapInclude 属性静态指定非已知的类型。

Answer 8

以String类型的方式返回XML就可以啦

Answer 9

List<FBook> fbs = FBookManager.GetFBookAll();
            XmlSerializer xmlSerializer = new XmlSerializer(fbs.GetType());            StringWriter stringWriter = new StringWriter();            xmlSerializer.Serialize(stringWriter, fbs);            string serializedXML = stringWriter.ToString();            return stringWriter;如果是string类型就会这样  
无法将类型“System.IO.StringWriter”隐式转换为“string”

Answer 10

string serializedXML = stringWriter.ToString();return stringWriter;返回值写错了
