XmlTextReader问题

Question

我试图解析这个xml，但是c＃不断抛出一个异常，说它有无效的字符。我无法直接从邮箱中复制文本，因此我已对其进行了筛选。

编辑：复制文字

<?xml version="1.0" encoding="UTF-8"?><user><id>9572</id><screen_name>fgfdgfdgfdgffg44</screen_name></user>

这是获取字符串

的代码

string strRetPage = System.Text.Encoding.GetEncoding(1251).GetString(RecvBytes, 0, bytes);

while (bytes > 0)
{
    bytes = socket.Receive(RecvBytes, RecvBytes.Length, 0);
    strRetPage = strRetPage + System.Text.Encoding.GetEncoding(1251).GetString(RecvBytes, 0, bytes);
}
start = strRetPage.IndexOf("<?xml");
string servReply = strRetPage.Substring(start);
servReply = servReply.Trim();
servReply = servReply.Replace("\r", "");
servReply = servReply.Replace("\n", "");
servReply = servReply.Replace("\t", "");

XmlTextReader txtRdr = new XmlTextReader(servReply);

XmlTextReader期望包含XML的URL而不是XML本身作为字符串。要使用XmlTextReader解析XML，您必须创建一个流并将其提供给XmlTextReader

using (StringReader stringReader = new StringReader(servReply))
{
    using (XmlTextReader xmlTextReader = new XmlTextReader(stringReader))
    {
        // Read the xml
    }
}
