c# - XmlTextReader 问题

Question

我尝试解析此 xml，但 C# 不断抛出异常，提示它包含无效字符。无法直接从messagebox中复制文字，所以我屏蔽了。

编辑:复制文本

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

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 需要一个包含 XML 而不是 XML 本身作为字符串的 url。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
    }
}
