linq - 如何在加入语句中结合条件

我有2个XML文件都包含“ID”和“语言”

我想做一个基于其中两个身份证和语言两个文件中等于加入我有这样的事情：

var data= 
from details in h_details.Descendants("ROW") 

join inst in instance.XPathSelectElements("//Row") 
on details.Element("ID").Value 
equals inst.XPathSelectElement("Field[@Name=\'h_id\']").Value 
and on details.Element("LANGUAGE").Value 
equals inst.XPathSelectElement("Field[@Name=\'h_lang\']").Value 

basically the "and" statement wont work, so how do i join based on 2 conditions?

匿名类型救援。

var data= 
    from details in h_details.Descendants("ROW") 
    join inst in instance.XPathSelectElements("//Row") 
    on new { 
    x = details.Element("ID").Value, 
    y = details.Element("LANGUAGE").Value 
    } equals new { 
    x = inst.XPathSelectElement("Field[@Name=\'h_id\']").Value, 
    y = inst.XPathSelectElement("Field[@Name=\'h_lang\']").Value 
    } 
    select ... ;
