Dynamic Linq - String.Split

Question

It appears that Dynamic Linq doesn't implement the String.Split method.

Is there a way achieve the same results with Dynamic Linq ?

Answer 1

Dynamic Linq does support String.Split and also calling other .net type methods as shown below

var query =
                db.Customers.Where("City.Split(\"abc\".ToCharArray()).Length == 1 and Orders.Count >= @1", "London", 10).
                OrderBy("CompanyName").
                Select("New(CompanyName as Name, Phone)");

It was able to convert the string to expression tree but as SQL doesn't have any string split operation it throws error if you run it on SQL

Answer 2

Answer to comment below:

string teststring = "one, two, three";

var x = from string z in (teststring.Split(',').AsEnumerable())
where z.Trim() == "two"
select z;

What exactly do you want to do? The following works just fine in LINQPad

from z in ("4,3,5,2,1".Split(',').AsEnumerable())
  select z
