Question

Hi, I am running C# in Vis. Studio 2019 community. Trying to get my program to populate the username in the program after entered. I can enter a name and the three scores and average them as the program needs but the name is not adding next to the "Students name: " in the program. Any help would be appreciated and please place a note for what I am doing wrong. Thank you

namespace DoprBox08
{
class CollegeStudent
{

public static void Main(string[] args)
{
Console.Title = ("College Student ");
Console.WriteLine("Please enter your name: \nand the three scores: ");

  

string name = Console.ReadLine();
int midTerm1 = int.Parse(Console.ReadLine());
int midTerm2 = int.Parse(Console.ReadLine());
int finalExam = int.Parse(Console.ReadLine());
CollegeStudent s = new CollegeStudent(name, midTerm1, midTerm2, finalExam); //Invoking the constructor

Console.WriteLine(s); //invokes ToString()
Console.ReadKey();
}
public override string ToString()
{
string str;
str = string.Format(" Student name: {0} \nSemester grade: {1}", StudentName, SemesterGrade());
Console.WriteLine();
return str;
}
private string studentName;
private int midTerm1;
private int midTerm2;
private int finalExam;

public string StudenName
{
get { return studentName; }
set { studentName = value; }

get { return midTerm1; }
set { midTerm1 = value; }

set { midTerm1 = value; }
}

}

public object StudentName { get; private set; }

public CollegeStudent(string studentName, int midTerm1, int midTerm2, int finalExam)
{
this.studentName = studentName;
this.midTerm1 = midTerm1;
this.midTerm2 = midTerm2;
this.finalExam = finalExam;
}
public double SemesterGrade()
{
double grade;
grade = 0.3 * MidTerm1 + 0.3 * MidTerm2 + 0.4 * FinalExam;
return grade;
}

}
}

Answer 1

There was a spell mistake in the property StudentName. Below is the incorrect and correct property name.

Incorrect

public string StudenName
{
get { return studentName; }
set { studentName = value; }
}

Correct

public string StudentName   
{
get { return studentName; }
set { studentName = value; }
}

Also there is aaditional public object StudentName { get; private set; } ----This line is not required once you fix the above mentioned problem. You can comment the this line.

Below is the corrected code. Added comments wherever required

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace DoprBox08
{
    class CollegeStudent
    {

        public static void Main(string[] args)
        {
            Console.Title = ("College Student ");
            Console.WriteLine("Please enter your name: \nand the three scores: ");



            string name = Console.ReadLine();
            int midTerm1 = int.Parse(Console.ReadLine());
            int midTerm2 = int.Parse(Console.ReadLine());
            int finalExam = int.Parse(Console.ReadLine());
            CollegeStudent s = new CollegeStudent(name, midTerm1, midTerm2, finalExam); //Invoking the constructor

            Console.WriteLine(s); //invokes ToString()
            Console.ReadKey();
        }
        public override string ToString()
        {
            string str;
            str = string.Format(" Student name: {0} \nSemester grade: {1}", StudentName, SemesterGrade());
            Console.WriteLine();
            return str;
        }
        private string studentName;
        private int midTerm1;
        private int midTerm2;
        private int finalExam;

        //This lin is problem. Spelling mistake - StudenName. It shoould be StudentName
        public string StudentName       
        {
            get { return studentName; }
            set { studentName = value; }
        }
        public int MidTerm1
        {
            get { return midTerm1; }
            set { midTerm1 = value; }
        }
        public int MidTerm2
        {
            get { return midTerm2; }
            set { midTerm1 = value; }
        }
        public int FinalExam
        {
            get { return finalExam; }
            set { finalExam = value; }
        }

        //This line of code should not be there. We have corrected the above property where Spelling mistake - StudenName. It shoould be StudentName
        //Commenting below line resolved the issue. Now Name is showing in the result
        //public object StudentName { get; private set; }   

        public CollegeStudent(string studentName, int midTerm1, int midTerm2, int finalExam)
        {
            this.studentName = studentName;
            this.midTerm1 = midTerm1;
            this.midTerm2 = midTerm2;
            this.finalExam = finalExam;
        }
        public double SemesterGrade()
        {
            double grade;
            grade = 0.3 * MidTerm1 + 0.3 * MidTerm2 + 0.4 * FinalExam;
            return grade;
        }

    }
}

After correcting code as mentioned above. Below is the screenshot of output
