lambda merge two list based on key

Question

I need to create one list (l_merged) from 2 lists (l1, l2) by merging the value of their properties (prop1, prop2).

var l1 = new List<string> { "key1", "key2", "prop1" };
var l2 = new List<string> { "key1", "key2", "prop2" };
var l_merged = new List<string> { "key1", "key2", "prop1", "prop2" };

Where l1.key1 == l2.key && l1.key == l2.key2

Any idea? thank you.

Please use C# for your example, then people might be able to understand exactly what you want — canton7, Mar 13 '19 at 14:48
i saw the question asked before, i would not make concat or addrange. union is not working for me as shown on error post below. thank you — Saad Choukair, Mar 13 '19 at 15:44

You may simply union them:

var result = l1.Union(l2).ToList();

That would produce `{key1, key2, prop1, key1, key2, prop2}`, which isn't what his example shows – canton7 Mar 13 '19 at 14:55
i tried this solution and i get the following error: CS1929 'IOrderedQueryable< – Saad Choukair Mar 13 '19 at 15:07
