c# - LINQ to SQL stored procedures issue -


i trying learn more web development c# , asp.net.

i using linq store values contact form in database, however, database requires 'policy id' generated calling stored procedure.

i have absolutely no idea how calling stored procedure, obtaining integer value generated , using value set policyid in table.

could provide me process work so:

execute sproc, return policy id. policyid, set policyno. add policyno db.policyid

i appreciate of information may appear quite amateurish, have never used linq nor stored procedures before. have been front end developer until now.

thanks in advance!

edit:

here c# code used far:

using (magtestdatacontext context = new magtestdatacontext())     {         //create new instance of tblpolicy object         tblpolicy policy = new tblpolicy();         var policyno = context.spnextpolicyid();         //add values field         policy.policyid = policyno;         policy.policyholder = tbname.text;         policy.email = tbemail.text;         policy.telephone = tbtelephone.text;         policy.address1 = tbaddressline1.text;         policy.address2 = tbaddressline2.text;         policy.address3 = tbaddressline3.text;         policy.address4 = tbaddressline4.text;         policy.postcode = tbpostcode.text;         policy.extrainfo10 = tbinsurer.text;         policy.extrainfo11 = ddreason.text;         policy.extrainfo12 = tbother.text;     }

it looks you're using entity framework. if so, can execute stored procedure using:

using (magtestdatacontext context = new magtestdatacontext()) {     var policyid = db.executequery<int>("declare @ret int; exec spnextpolicyid @ret output; select @ret").single(); }

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
