在 linq-to-sql 中返回 bool true

Question

I have an object model that contains a boolean field MyBool. I want populate that boolean with a linq-to-sql query based on whether or not the database field MyField contains data.

This is what I have:

var TheQuery = (from x in .....
                where .....
                select new MyModel{

                    MyBool = x.MyField.Contains(*)

                }).ToList();

I'm trying with the.Contain extension method but it's not working. Any suggestions?

Thanks

Answer 1

I'd suggest that, according to your incomplete example,

MyBool = x.MyField.Contains(*)

should be

MyBool = x.MyField.Contains("*")

And you should have brackets around the Linq expression.

A more complete example might be useful, though.
