C# 从XML中选择特定的节点值

我有以下XML文档：

  <?xml version="1.0" encoding="utf-8" ?> 
  <appSettings>
  <Path> blahblahblah </Path> 
  <PathValue> blahblahblah </PathValue> 
  <domainName> blahblahblah </domainName> 
  <SuperUserEmail> blahblahblah </SuperUserEmail> 
  <SuperUserName> blahblahblah </SuperUserName> 
  <UserName> blahblahblah </UserName> 
  <Password> blahblahblah </Password>       
  <connectionstring>Data Source=ABC\SQLEXPRESS;Initial Catalog=mail;User ID=sa;Password=sa@</connectionstring> 
  </appSettings>

但它似乎不起作用。你知道怎么做吗？

试试看

XmlNode node = xml.DocumentElement.SelectSingleNode("/appSettings/connectionstring");

string nodeval=node.InnerText;

你能分享你的错误屏幕吗。它没有被上传。在调试它时，我得到的只是

System.XML.xmlementlist

查看此链接“”我希望这可能对您有所帮助

XmlNode node = xml.DocumentElement.SelectSingleNode("/appSettings/connectionstring");

string nodeval=node.InnerText;
