LINQ to Entity, using a SQL LIKE operator

Question

I have a LINQ to ENTITY query that pulls from a table, but I need to be able to create a \"fuzzy\" type search. So I need to add a where clause that searches by lastname IF

Answer 1

I think you want to use the Contains() function of the string parameter like this:

var query = from mem in context.Member
    where mem.LastName.Contains("xxx")
    orderby mem.LastName, mem.FirstName
    select new
    {
        FirstName = mem.FirstName,
        LastName = mem.LastName,
    };

I think you can also use StartsWith() and EndsWith() which would be equivalent to the SQL 'xxx%' and '%xxx" respectively.
