This code can help u char[] textValue = textBox1.Text.ToCharArray(); foreach (char c in textValue) lblAsciiValue.Text += (int)©;

As u r opening the file before deleting the same file so as u open the file for writting then obviously it is used by the process ,so just delete that line I m using following code for deleting the file and it is working very fine string fileName = textBox1.Text.Trim(); try { if (File.Exists(fileName)) { //File.OpenWrite(fileName); File.Delete(fileName); MessageBox.Show("File Deleted Successfully"); } else { MessageBox.Show("File does not exists"); } } catch (FileNotFoundException ex) { MessageBox.Show(ex.Message.ToString()); }
