Try this code sample /// /// method to check not only if a file is already open, but if the /// but also if read and write permissions exist /// /// the file we wish to check /// public bool isFileOpenOrReadOnly(ref string file) { try { //first make sure it's not a read only file if ((File.GetAttributes(file) & FileAttributes.ReadOnly) != FileAttributes.ReadOnly) { //first we open the file with a FileStream using (FileStream stream = new FileStream(file, FileMode.OpenOrCreate, FileAccess.Read, FileShare.None)) { try { stream.ReadByte(); return false; } catch (IOException) { return true; } finally { stream.Close(); stream.Dispose(); } } } else return true; } catch (IOException) { return true; } } more reference link --->Thanks.

So you want someone to write the program for you? Note that when your teacher sees the code you get, you will be in trouble when you submit it as your own. It is called plagiarizing.
