Caution noteCaution

When you compile a set of characters with a particular cultural setting and retrieve those same characters with a different cultural setting, the characters might not be interpretable, and can cause an exception to be thrown.

The following code example demonstrates the use of this constructor. For the complete context of this example, see the IsolatedStorageFileStream overview.


IsolatedStorageFileStream source =
    new IsolatedStorageFileStream(this.userName, FileMode.OpenOrCreate,
    isoFile);
// This is the stream from which data will be read.
Console.WriteLine("Is the source file readable? " + (source.CanRead ? "true" : "false"));
Console.WriteLine("Creating new IsolatedStorageFileStream for Archive.");

// Open or create a writable file.
IsolatedStorageFileStream target =
    new IsolatedStorageFileStream("Archive\\ " + this.userName,
    FileMode.OpenOrCreate,
    FileAccess.Write,
    FileShare.Write,
    isoFile);
