如何检查

xrlist

中是否存在

XTclist

值

XR

：

<result>
 <claims type="Subject">
          <scope_of_claim>Full scope</scope_of_claim>
          <claim_date>02/28/2009</claim_date>
          <claim_age months="1" years="2" />
</claims>
 <claims type="Vehicle">
          <scope_of_claim>Full scope</scope_of_claim>
          <claim_date>12/8/2010</claim_date>
          <claim_age months="1" years="2" />
</claims>

代码：

var XRclist = XR.Descendants("claims").Attributes("type");
    var xTclist = XT.Descendants("claims").Attributes("type");

         foreach (var c in xTclist)
         {
             if (XRclist.Contains(c.value)) // This line need to be corrected
             {
                Do some thing.
             }
             else
             {
               Do something else.
             }
         }

您可以在以下任意位置使用扩展方法：

而不是

if（xrlist.Contains（c.value））

使用

if（xrlist.Any（x=>x.Value.Equals（c.Value））

var XRclist = XR.Descendants("claims").Attributes("type");
    var xTclist = XT.Descendants("claims").Attributes("type");

         foreach (var c in xTclist)
         {
             if (XRclist.Contains(c.value)) // This line need to be corrected
             {
                Do some thing.
             }
             else
             {
               Do something else.
             }
         }
