Build Errors

14y1.9kVisual Basic .NET

This program is compiling well but message box says there were build errors. Please anyone can explain the reason.

using System;
public class CreateStudent
{
public static void Main()
{
Student oneSophomore = new Student();

oneSophomore.SetId(951);
oneSophomore.SetName("Ross");
oneSophomore.SetGPA(3.5);

Console.WriteLine
("The student named {0} has ID # is {1} and a gpa of {2}",
oneSophomore.GetName(), oneSophomore.GetId(), oneSophomore.GetGPA());

Console.ReadLine();
}
}
class Student
{
private int idNumber;
private string lastName;
private double gradePointAverage;

public int GetId()
{
return idNumber;
}
public void SetId(int id)
{
idNumber = id;
}

public int GetName()
{
return lastName;
}
public void SetName(string name)
{
lastName = name;
}

public double GetGPA();
{
return gradePointAverage;
}
public void SetGPA(double gpa);
{
gradePointAverage = gpa;
}
}
//The student named Ross has ID # is 951 and a gpa of 3.5

Hi Maha,

Your mistake is public double GetGPA();
Repalce public double GetGPA(); with public double GetGPA()

Note :- semicolon(;)

Your solution

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

namespace ConsoleApplication1
{
    //class Program
    //{
    //    static void Main(string[] args)
    //    {
    //    }
    //}

    public class CreateStudent
    {
        public static void Main()
        {
            Student oneSophomore = new Student();

            oneSophomore.SetId(951);
            oneSophomore.SetName("Ross");
            oneSophomore.SetGPA(3.5);
            Console.WriteLine("The student named {0} has ID # is {1} and a gpa of {2}", oneSophomore.GetName(), oneSophomore.GetId(), oneSophomore.GetGPA());
            Console.ReadLine();
        }
    }
    class Student
    {
        private int idNumber;
        private string lastName;
        private double gradePointAverage;

        public int GetId()
        {
            return idNumber;
        }
        public void SetId(int id)
        {
            idNumber = id;
        }

        public string GetName()
        {
            return lastName;
        }
        public void SetName(string name)
        {
            lastName = name;
        }

        public double GetGPA()
        {

            return gradePointAverage;
        }
        public void SetGPA(double gpa)
        {
            gradePointAverage = gpa;
        }

    }
}

Thank you

That error typically occurs in Visual Studio if you try to change and rebuild a project when there's an instance of it already running.

So just make sure that you've closed the previous instance before you do this.

In some programs following error message is appearing during the first execution. But Program is executing well at the 2nd execution. I don't know why. Anyone knows the reason.

Error generating Win32 resource: The process cannot access the file because it is being used by another process.

Yes, that version compiles and runs fine :)

Satyapriya was right that there were errors - 3 of them in fact.

Unbelievably, I aleady had another program called CreateStudent.cs on my machine, copied yours to CreateStudent2.cs, got distracted and then compiled and ran the first version (which, of course, worked fine) rather than your program! Sorry about that.

Hi Satyapriya Nayak Thank you very much for identifying the error.

Hi Vulpes

I use Microsoft Visual C# 2010 Express, a free download from Microsoft this may produce error message if the program is in the Traditional method. Modified version of this program did not producing any error message. What you think?

Modified version as follows:

using System;
public class CreateStudent
{
public static void Main()
{
Student oneSophomore = new Student();

oneSophomore.Id = 951;
oneSophomore.Name = "Ross";
oneSophomore.GPA = 3.5;

Console.WriteLine
("The student named {0} has ID # is {1} and a gpa of {2}",
oneSophomore.Name, oneSophomore.Id, oneSophomore.GPA);

Console.ReadKey();
}
}
class Student
{
private int idNumber;
private string lastName;
private double gradePointAverage;

public int Id
{
get { return idNumber; }
set { idNumber = value; }
}
public string Name
{
get { return lastName; }
set { lastName = value; }
}
public double GPA
{
get { return gradePointAverage; }
set { gradePointAverage = value; }
}
}
//The student named Ross has ID # is 951 and a gpa of 3.5

It sounds to me like you make have another file, program.cs, as well as the code you've posted above.

I'd check your files in Solution Explorer and, if program.cs is present, just delete it and rebuild.

I just successfully compiled and ran the program.

What build errors are being reported?
