在XML 檔案中若節點中有Attribute 的值，即可利用此值作為搜尋條件，找到此值後把Element 內的值讀取出來

RuleBase.xml 的檔案內容

<?xml version="1.0" encoding="utf-8"?>
<RuleBase>
  <Simulation>
    <Process ID="Mail">
      <TimeOutCount>301</TimeOutCount>
      <TimeLimit>600</TimeLimit>
    </Process>
  </Simulation>
</RuleBase>

using System.Xml.Linq;

try  // 讀取XML 設定檔中的參數
           {
               XElement root = XElement.Load("RuleBase.xml");
               IEnumerable<XElement> tests =
                   from el in root.Elements("Simulation").Elements("Process")
                   where (string)el.Attribute("ID") == "Mail"
                   select el;

               foreach (XElement el in tests)
               {
                   MessageBox.Show(el.Attribute("ID").ToString() + " : " + el.Element("TimeOutCount").Value);  //查詢xml Element 的值
               }

           }
           catch (Exception ex)
           {

               MessageBox.Show(ex.Message);
           }
