Question

Xml阅读问题。

private DataPDU Deserialize(string filepath)
    {
        XmlSerializer deserializer = new XmlSerializer(typeof(DataPDU));

        UTF8Encoding utf8 = new UTF8Encoding(true);
        StreamReader reader = new StreamReader(filepath, utf8);

        object obj = deserializer.Deserialize(reader);  //error raising here
        DataPDU XmlData = (DataPDU)obj;
        reader.Close();
        return XmlData;
    }

如果我删除＆＃34; Saa：＆＃34;从标签我的代码工作正常。但文件提供者以上述格式提供in文件。你能帮忙吗？部分错误跟踪吼叫。

上周我用同样的解决方案帮助了某人。使用Regex删除命名空间

       public DataPDU Deserialize(string filepath)
        {
            XmlSerializer deserializer = new XmlSerializer(typeof(DataPDU));

            UTF8Encoding utf8 = new UTF8Encoding(true);
            StreamReader reader = new StreamReader(filepath, utf8);
            string text = reader.ReadToEnd();
            string pattern = "(</?)(\\w+:)";
            string fixedText = Regex.Replace(text,pattern,"$1");
            StringReader fixedReader = new StringReader(fixedText);

            object obj = deserializer.Deserialize(fixedReader);  //error raising here
            DataPDU XmlData = (DataPDU)obj;
            reader.Close();
            return XmlData;
        }

＆＃39;：＆＃39;导致{＆＃34; XML文档中存在错误（2,6）。＆＃34;}
