IsolatedStorageFileStream.CanRead Property

Gets a Boolean value indicating whether the file can be read.

Namespace:  System.IO.IsolatedStorage
Assembly:  mscorlib (in mscorlib.dll)

public override bool CanRead { get; }

Property Value

Type: System.Boolean
true if an IsolatedStorageFileStream object can be read; otherwise, false.

Use this property to determine whether the IsolatedStorageFileStream object can be read.

The following code example demonstrates how you could use the CanRead property, as a check to see whether a stream can be read before calling the Read or BeginRead methods. 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);
