I am able to read my text file however when I go and click my edit button it moves all the current rows in the text file to the top row and doesn't update anything. Also how would I go about adding a row to the text file without moving the rows?

private void btnEdit_Click(object sender, EventArgs e)

{

  BugTrackers cs = Bugs[index];

  // DisplayBugs();

  // Update datafile

  UpdateBugsInfo();

}

private void UpdateBugsInfo()

{

  if (lstBugs.SelectedIndex > -1)

  {

    System.IO.StreamWriter sw = new System.IO.StreamWriter("smBugs.txt", false);

    for (int i = 0; i <= Bugs.Count - 1; i++)

    {

      sw.Write(Bugs[i].BugsName);

      sw.Write(",");

      sw.Write(Bugs[i].BugsDesc);

    }

    sw.Close();

  }

}

The StreamWriter object you are creating is having wrong parameter value for append. You need to set that as true OR just remove that parameter since it’s default value is true.

System.IO.StreamWriter sw = new System.IO.StreamWriter("smBugs.txt", true);

OR

System.IO.StreamWriter sw = new System.IO.StreamWriter("smBugs.txt");

Here is the link from Microsoft.

https://docs.microsoft.com/en-us/dotnet/api/system.io.streamwriter.-ctor?view=netframework-4.7.2#System_IO_StreamWriter__ctor_System_String_System_Boolean_

You are also not using the using statement, which ensures the StreamWriter object is removed from memory when no longer needed. Please go through this article to understand it better.

Hope this helps!

}

This is the code in its entirety. I have a list box with 2 text boxes to hold the bug name and description. I have 3 buttons Add, Edit and Delete. If an item is selected from the listbox it will display the bugname and description. If the entry needs updated changes are made and will change the information needed. If a new bug is added you would use the add button same for the delete button.
