Red Lines are shown under v.user_passport, v.mobilenumber); two parameters.

                var v = db.Users.Where(modal => modal.user_name.Equals(User.user_name)).Where(modal => modal.user_passport.Equals(User.user_passport)).SingleOrDefault();


                if (v != null)
                {
                    UserInfo(v.user_name, v.user_fname, v.user_bloodGp, v.user_nationality, v.usertype, v.status, v.gender, v.usercnic, v.user_passport, v.mobilenumber);

Its run-time error. string is passed to variable where integer is expected and and its trying to cast string to integer causing Invalid cast exception. correct the order of parameters being passed.

You can pass only the v variable to your UserInfo function instead of passing all those parameters

You are not passing the parameters in the right order, modify your call to that:

UserInfo(v.user_name, v.user_fname, v.usercnic, v.user_passport, v.user_bloodGp, v.user_nationality, v.usertype, v.status,  v.mobilenumber, v.gender);

If you are not using named parameters, you have always to be careful about the order of the parameters when you are calling a function/method

Your mobilenumber is declared as int, and you are trying to pass a string, please do a cast when calling the UserInfo

UserInfo(v.user_name, v.user_fname, v.user_bloodGp, v.user_nationality, v.usertype, v.status, v.gender, v.usercnic, v.user_passport, int.Parse(v.mobilenumber));
