我有2泛型列表名单，其中，TYPE1＆GT; L1 ，名单，其中，2型＆GT; L2 在C＃3.5

I have 2 generic Lists List<type1> L1 , List<type2> L2 in C# 3.5

问题： TYPE1有一个名为键1和type2的属性有一个属性叫做KEY2 如何合并的键1 =键2 L1和L2。 这两个列表都是无序，但我欢迎就如何名单根据属性进行排序的任何想法。

Problem: type1 has an attribute called "key1" and type2 has an attribute called "key2" How to merge L1 and L2 on key1 = key2. Both lists are unsorted but I'm welcome to any ideas on how to sort the lists based on the attribute.

我希望能够合并在一个关键的两个列表。我知道这不是一本字典，它会一直很好，如果它是，但有一个非常特殊的原因，他们的名单，我不会得到到，因为这是不相关的。

I'd like to be able to merge the two lists on a key. I know it's not a dictionary and it would've been nice if it was but there is a very specific reason why they are lists which I will not get in to because that is irrelevant.

推荐答案

我相信你要求的加入操作。这是简单的，但你将需要更加具体，以获得更好的答案。

I believe you're asking for the Join operation. It's straightforward, but you are going to need to be more specific to get better answers.

var joined = from item1 in L1
             join item2 in L2
             on item1.Key1 equals item2.Key2
             orderby item1.Key1
             select new 
             {
                 // your selected objects/properties here
             };
