I'm trying to do this in a C# Console App.(NET Framework).I've attached the Code that will be required to complete. Any Guidance will be appreciated.

C# Console File I/O Project Assignment

Working with files and being able to process data in and out of a file is critical to the programmer’s role. Almost every organization will have to deal with files one way or another. For example, it is very common for accountants to use spreadsheets for calculations and sometimes you are called to help them with their data problems.

This assignment helps you become familiar with handling files and processing data between the program and the file. Review the project requirements below and use the sample C# source code to get you started. While reading the source code you will find some of the problems and during runtime, you will find more issues. The source code is not broken and it works within a C# console program. The main objective of this week’s assignment is to fix the source code and make the code perform more efficiently.

File I/O Console Program Requirements:

1. Add a new enhancement to the source code of your choice and make it a feature that is the file I/O related.
2. Fix the data write to file problems so the outbound file does not keep appending the data to the file. The file should truncate and then load the data.
3. Write C# variables for storing system paths and file names
4. Write C# for error handling
5. Make the program load a file into the program
6. Give the program a menu with options
7. Write a function for exiting the program

if (!System.IO.File.Exists(@"C:\Users\terry.brookhouser\Desktop\data2.txt"))
{
System.IO.File.Create(@"C:\Users\terry.brookhouser\Desktop\data2.txt");
}
  
using (System.IO.StreamWriter file = new System.IO.StreamWriter(@"C:\Users\terry.brookhouser\Desktop\data2.txt", true))
{
file.WriteLine("Welcome Students!!!!");
file.WriteLine("As we are learning about new C# programming features.");
file.WriteLine("You should be having lots of fun in this class.");
}

string Path = System.IO.File.ReadAllText(@"C:\Users\terry.brookhouser\Desktop\data2.txt");
Console.WriteLine(Path);
Console.ReadKey();
}
catch (Exception em)
{
Console.WriteLine("An error occured: " + em.Message);
}
