}

What I have tried:

I have tried debugging and analyzing my code with no errors.

Based on your expectations, programs need to do certain things. We don't know what you expect to happen after your program starts. A program only shows "results" if told to.

I'm expecting to see the text file information in a text box.

Is this a Windows Forms app or a Console app? Your code is very confused and trying to use both.

Do you get any messages at all when it runs? Does that MessageBox.Show call display anything?

If in a Windows Forms app, those calls to Console.ReadLine will do nothing at all, they can be removed.

Here is what I'm trying to do: Create a program that stores student grades in a text file. The file should contain the name, ID number, class taken and grade of every student. Allow the user to load a grade file and display its contents in a read-only TextBox. The entries should be displayed in the following format:
LastName, FirstName: ID# Class Grade

Some sample data:
Jones, Bob: 1 "Introduction to Computer Science" "A-"
Johnson, Sarah: 2 "Data Structures" "B+"
Smith, Sam: 3 Data Structures" "C"

So I created a "Form" with a text box and a text file with the information then I created my coding. When debugging, there are no errors but the text file is not showing in the text box. I am very new to C# so this is why I'm having a hard time. Any assistance would be greatly appreciated.

OK, scrap the code you have and start over. There is such much wrong with the code you posted that it is not practical to try to salvage it. It's quicker to just start from scratch.

Create a new Windows Forms project and you at least have a known good starting point.

The program '[9460] StudentGrades.exe' has exited with code 0 (0x0).

When a program exits with code 0, it means there was no problem with the code execution.

Skipped loading symbols. Module is optimized and the debugger option 'Just My Code' is enabled.

That is a setting that you have enabled in Visual Studio, and thus, the debugger will not load the symbols for dependencies. The System.dll and System.Drawing.dll is not a module that you are developing, rather you are depending upon them. You can disable that: Debug user code with Just My Code - Visual Studio (Windows) | Microsoft Learn[^].

Are you printing something to the console? Please share the code that you wrote for the program and what output you are expecting.

Solution 2

C#

public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }
    }

Your Form should look something like what is shown above.
You can't just turn a console app into a windows form app.
