The following example accesses a file for writing. This code example is part of a larger example provided for the IsolatedStorageFile class.
// Write to an existing file: MyApp1\SubDir1\MyApp1A.txt // Determine if the file exists before writing to it. string filePath = Path.Combine(subdirectory1, "MyApp1A.txt"); if (store.FileExists(filePath)) { try { using (StreamWriter sw = new StreamWriter(store.OpenFile(filePath, FileMode.Open, FileAccess.Write))) { sw.WriteLine("To do list:"); sw.WriteLine("1. Buy supplies."); } } catch (IsolatedStorageException ex) { sb.AppendLine(ex.Message); } }
