问题描述
显示我对Linq to Xml的理解不清,并寻求帮助.我正在尝试执行此强制转换,然后执行查询.
displaying my weak understanding of Linq to Xml and asking for help. I was trying to do this cast and then do a query.
XmlDocument doc == 新 XmlDocument((); |
doc.Load(path); |
,XmlNodeList rootNodeList = doc .GetElementsByTagName("root"); |
XmlNode rootNode = rootNodeList .Item(0); |
的System.Collections.IEnumerable que ==(System.Collections.IEnumerable)rootNode.ChildNodes .Cast < XmlNode > ; (); |
XmlNode元素; |
qMethods que |
elem.Name == this.ext + Globals.hostName |
请选择(elem).Take(1); |
XmlDocument doc = new XmlDocument ( ); |
doc.Load ( path ); |
XmlNodeList rootNodeList = doc.GetElementsByTagName ( "root" ); |
XmlNode rootNode = rootNodeList.Item ( 0 ); |
System.Collections.IEnumerable que = ( System.Collections.IEnumerable )rootNode.ChildNodes.Cast<XmlNode> ( ); |
XmlNode elem; |
var qMethods = ( from elem in que |
where elem.Name == this.ext + "Files_" + Globals.hostName |
select elem ).Take ( 1 ); |
推荐答案
我认为您将需要使用具体的实现,因此LINQ引擎可以使用正确的查询.传入XNode;不要将其转换为IEnumerable.
I think you're going to need to use the concrete implementations so the LINQ engine can use the correct queries. Pass in the XNode; don't cast it to IEnumerable.
