command.ExecuteNonQuery returns -1

I would like to know what does the value -1 indicate when I execute the command.ExecuteNonQuery  which excutes a stored procedure.

iResult = command.ExecuteNonQuery

iResult shows -1
LVL 1

For UPDATE, INSERT, and DELETE statements, the return value is the number of rows affected by the command. When a trigger exists on a table being inserted or updated, the return value includes the number of rows affected by both the insert or update operation and the number of rows affected by the trigger or triggers. For all other types of statements, the return value is -1. If a rollback occurs, the return value is also -1.

if you have an identity on the table you can use
return @@IDENTITY;

mycom.CommandType = CommandType.StoredProcedure;
SqlParameter sp = new SqlParameter();
sp.Direction= ParameterDirection.ReturnValue;
mycom.Parameters.Add(sp);
mycom.ExecuteNonQuery();
string s= mycom.Parameters[0].Value.ToString(); or whatever you need it as
