如何使用LINQ lambda组合多个列表

Question

I have two lists:

list1 = [a,b,c,4]
list2 = [1,23,5,6]

Now I need to create an anonymous object using linq lambda.

Something like.

list1 = DataTable.AsEnumerable().toList();
list2 = DataTable.AsEnumerable().toList();

var result = list1.Where(x => x.Field<int>(1) == 2018).Select(x => new[] {
new {x = "XYZ", y = x[0], z = list2[0]},
....}



}

How do I go about doing this?

Answer 1

You need Zip Linq method, consider this example:

int[] list1 = {1, 2, 3};
string[] list2 = {"a", "b", "c"};

var result = list1.Zip(list2, (i, s) => new {y = i, z = i});

Answer 2

Your code is fine, it just needs some small fixes:

            string [] list1 = { "a", "b", "c", "4" };
            int[] list2 = { 1, 23, 5, 6 };
            object[] list3 = { "test", DateTime.Now, 56 };

            var result = list1.Where(x => x == "a").Select(x =>
                  new { x = "XYZ", y = x[0], z = list2[0], t = list3[1] }).ToList();
