c# - Linq to Sql where condition String NotSupported Exception -

-

i trying pull password length asp.net tables following linq sql query 

(from t1 in aspnet_users join t2 in aspnet_memberships on t1.userid equals t2.userid decrypt(t2.password).length< 8 ||   decrypt(t2.password).length>16   select new { t1.username,   t2.email,   length=decrypt(t2.password).length})

but when try run code. getting following error.

notsupportedexception: method 'system.string a(system.string)' has no supported translation sql.

can guys give me idea fix it?

you cannot use c# method, in case decrypt, in linq sql. works linq object not linq sql whole linq query converted sql query , compiler fails recognize methods.

for this, can convert linq code lambda expression, , make func<> delegate decrypt, , use in clause.
