mysql - Returning value from Stored Procedure and using it in C# -

i have created function "recover(string useremail)" takes in user's email when he/she forgets login information. function runs stored procedure called "recover_password", return username , password can send email user. not familiar syntax creating simple stored procedure returns information. not familiar storing returned value in c# can make use of it.

recover_password:

   create definer=`root`@`localhost` procedure `recover_password`(in email char(40)) begin   select username,password  userdata   email=contactemail;  end 

recover(string useremail):

 public actionresult recover(string useremail)     {         login model = new login();         mysqlconnection connect = dbconnection();         mysqlcommand cmd = new mysqlcommand("recover_password",connect);         cmd.commandtype = commandtype.storedprocedure;         cmd.parameters.addwithvalue("@email", useremail);         mysqldatareader rd = cmd.executereader();         while (rd.read())         {             if (useremail == rd["contactemail"].tostring())             {                 mailmessage msg = new mailmessage();                 msg.to.add(useremail);                 msg.subject = "recovered login information";                 msg.body = "hello," + environment.newline + "your login information: "; //this want able use returned value             }         }         return null;     }
