Property Value
true
if an IsolatedStorageFileStream object can be read; otherwise, false
.
Examples
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.
// This is the stream to which data will be written.
IsolatedStorageFileStream^ source = gcnew IsolatedStorageFileStream( this->userName,FileMode::OpenOrCreate,isoFile );
// This is the stream from which data will be read.
Console::WriteLine( "Is the source file readable? {0}", (source->CanRead ? (String^)"true" : "false") );
Console::WriteLine( "Creating new IsolatedStorageFileStream for Archive." );
// Open or create a writable file.
IsolatedStorageFileStream^ target = gcnew IsolatedStorageFileStream( String::Concat("Archive\\",this->userName),FileMode::OpenOrCreate,FileAccess::Write,FileShare::Write,isoFile );
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);
' Open or create a writable file.
Dim target As New IsolatedStorageFileStream("Archive\ " & Me.userName, _
FileMode.OpenOrCreate, FileAccess.Write, FileShare.Write, isoFile)
Remarks
Use this property to determine whether the IsolatedStorageFileStream object can be read.
