Like operator or using wildcards in LINQ to Entities

Question

I\'m using LINQ 2 Entities. Following is the problem:

string str = \'%test%.doc%\' 
.Contains(str) // converts this into LIKE \'%~%test~%.doc~%%\'

Answer 1

The SQL method PATINDEX provides the same functionality as LIKE. Therefore, you can use the SqlFunctions.PatIndex method:

.Where(x => SqlFunctions.PatIndex("%test%.doc%", x.MySearchField) > 0)
