获得使用LINQ

Question

从XML键值对如何使用LINQ我提取此XML例如键值对：

<foo> 
<add key="key1" Value="val1"/> 
<add key="key2" Value="val2"/> 
<add key="key3" Value="val3"/> 
<foo/> 

Answer 1

试试这个：

string text = "<foo>...</foo>"; 
var pairs = XDocument.Parse(text) 
        .Descendants("add") 
        .Select(x => new { Key = x.Attribute("key").Value, 
             Value = x.Attribute("Value").Value }) 
        .ToList(); 

Answer 2

XDocument fooXML = new XDocument.Load("foo.xml") 
var query = from a in fooXML.Element("foo").Elements("add") 
      select new 
      { 
       key = a.Attribute("key").Value, 
       val = a.Attribute("Value").Value 
      }; 
// Then do what you want with the query...
