Convert string to LINQ query

which method or way should be us开发者_开发问答ed to convert a string to a linq query ?

Environment: VS 2010/C#

I'm not sure of what you are trying to achieve but if you are referring to creating linq queries from strings you could use the dynamic linq library, check it out here http://weblogs.asp.net/scottgu/archive/2008/01/07/dynamic-linq-part-1-using-the-linq-dynamic-query-library.aspx

You have to do something like this:

var query =
                db.Customers.Where("Country== @0 and Orders.Count >= @1", "Costa Rica", 10).
                OrderBy("CompanyName").
                Select("New(CompanyName as Name, Phone)");

some parts could be taken from strings, some others (tables) cant

Converting a string to Linq query isn't directly possibly with out some parsing and translation into System.Linq.Expression objects. Neither is trivial.

Check this out for one example.
