linq - C# functions in LinqToSql request -

i have 1 problem. need use c# function in linq sql request. example:

      void request()       {              var db = new dataclasses1(connectionstring);             var result =                  in db.stats                 function(a.sourcename)                 select a;         }         bool function(string sourcename)         {              return true;         } 

this dont work because boolean function(string sourcename) cant change sql request. need use c# functions in linq sql?

you need add asenumerable linq query:

  void request()   {          var db = new dataclasses1(connectionstring);         var result =              in db.stats.asenumerable()             function(a.sourcename)             select a;     }     bool function(string sourcename)     {          return true;     }
