Remarks

Use this class to read, write and create files in isolated storage.

Since this class extends FileStream, you can use an instance of IsolatedStorageFileStream in most situations where a FileStream might otherwise be used, such as to construct a StreamReader or StreamWriter.

Examples

The following example uses a StreamReader object to read an IsolatedStorageFileStream that is obtained from an isolated storage file.
