Index Error on file

[arggg]

When I run this if the file trying to be renamed / moved is the current file running to skip it. However I get an error that says

Index was out of range. Must be non-negative and less than the size of the collection

However I don't know where it would be trying to access the collection UpdatedFiles over the array size.

try
                {
                    lblStatus.Text = "Installing...";
                    Application.DoEvents();
                    for (int i = 0; i <= UpdatedFiles.Count; i++)
                    {
                        //MessageBox.Show(UpdatedFiles[i].ToString().ToLower() + "!=" + thisFile.ToLower());
                        if (!UpdatedFiles[i].ToString().ToLower().Equals(thisFile.ToLower()))
                        {
                            lblFile.Text = UpdatedFiles[i].ToString();
                            Application.DoEvents();
                            if (File.Exists(UpdatedFiles[i].ToString()))
                            {
                                File.Delete(UpdatedFiles[i].ToString());
                            }
                            File.Move("~" + UpdatedFiles[i].ToString(), UpdatedFiles[i].ToString());
                        }                    
                    }
                }
                catch(SystemException ex)
                {
                    MessageBox.Show(ex.Message + " (" + nodeFile["FileName"].InnerText + ")",
                        "An Error Occurred During Installation!",
                        System.Windows.Forms.MessageBoxButtons.OK,
                        System.Windows.Forms.MessageBoxIcon.Error,
                        System.Windows.Forms.MessageBoxDefaultButton.Button1);
                    //MessageBox.Show(_text);
                }

Nevermind I found it. The FOR should of been i < UpdatedFiles.Count()

I was too late at saying that. Yes, the index is zero based so going to <=length will go over the number of indexes
