C# / Windows Forms: error cs1519

Question

Hi, I'm working on a graphics transformation program, setting up a listbox to read in the names of files in a directory. The code is based off an example from my instructor, so I thought it would work fine, but it seems to create errors everywhere. I googled "error CS1519: Invalid token ‘,’ in class, struct, or interface member declaration", but what I found looked unapplicable. Here it is:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO;

namespace Transformer
{
 public partial class Transformer : Form
 {
  /* Initialize parameters */
  private bool drawAxes = true;
  private bool drawGrid = true;

  private List<ObjectSettings> dispObjects = new List<ObjectSettings>();

  /* Initialize form */

  public Transformer()
  {
   InitializeComponent();
  }

  private void Transformer_Load(object sender, EventArgs e)
  {
  }


  /* Populate available objects listbox */

  private int selFile = 0;
  private string currentDir = Directory.GetCurrentDirectory();

  // errors start around here

  private string[] fileEntries = Directory.GetFiles(currentDir+@"\Objects");
  foreach (string s in fileEntries) {
      int start = s.LastIndexOf(@"\");
      int end = s.LastIndexOf(@".");
      availObjectsListBox.Items.Add(s.Substring(start + 1, end - start - 1));
  } // end foreach
 }
}

Answer 1

That's because you need to put:

 foreach (string s in fileEntries) {
      int start = s.LastIndexOf(@"\");
      int end = s.LastIndexOf(@".");
      availObjectsListBox.Items.Add(s.Substring(start + 1, end - start - 1));
  }

in a function.

Maybe you can do something like:

private void Transformer_Load(object sender, EventArgs e)
  {

 int selFile = 0;
string currentDir = Directory.GetCurrentDirectory();
string[] fileEntries = Directory.GetFiles(currentDir+@"\Objects");
  foreach (string s in fileEntries) {
      int start = s.LastIndexOf(@"\");
      int end = s.LastIndexOf(@".");
      availObjectsListBox.Items.Add(s.Substring(start + 1, end - start - 1));
    } // end foreach
  }

Note that you put the foreach loop inside the Transformer_Load function; of course, you can put it in any other function. And note that there is no modifier (private) in front of selFile, currentDir and fileEntries variable.

Look where the errors start!

You cant have statements in the class body. It needs to be in a method/property/constructor.
