Constructors

	Name	Description
	IsolatedStorageFileStream(String, FileMode, IsolatedStorageFile)	Initializes a new instance of the IsolatedStorageFileStream class giving access to the file designated by path, in the specified mode, and in the context of the IsolatedStorageFile specified by isf.
	IsolatedStorageFileStream(String, FileMode, FileAccess, IsolatedStorageFile)	Initializes a new instance of the IsolatedStorageFileStream class giving access to the file designated by path in the specified mode, with the specified file access, and in the context of the IsolatedStorageFile specified by isf.
	IsolatedStorageFileStream(String, FileMode, FileAccess, FileShare, IsolatedStorageFile)	Initializes a new instance of the IsolatedStorageFileStream class giving access to the file designated by path, in the specified mode, with the specified file access, using the file sharing mode specified by share, and in the context of the IsolatedStorageFile specified by isf.

Properties

	Name	Description
	CanRead	Gets a Boolean value indicating whether the file can be read. (Overrides FileStream.CanRead.)
	CanSeek	Gets a Boolean value indicating whether seek operations are supported. (Overrides FileStream.CanSeek.)
	CanTimeout	Gets a value that determines whether the current stream can time out. (Inherited from Stream.)
	CanWrite	Gets a Boolean value indicating whether you can write to the file. (Overrides FileStream.CanWrite.)
	Length	Gets the length of the IsolatedStorageFileStream object. (Overrides FileStream.Length.)
	Name	When it is called by trusted applications, gets the name of the file stream that was passed to the constructor. (Inherited from FileStream.) In Silverlight for Windows Phone Windows Phone OS 7.1, this member is Name. In XNA Framework Xbox 360, this member is Name.
	Position	Gets or sets the current position of the current IsolatedStorageFileStream object. (Overrides FileStream.Position.)
	ReadTimeout	Gets or sets a value, in miliseconds, that determines how long the stream will attempt to read before timing out. (Inherited from Stream.)
	WriteTimeout	Gets or sets a value, in miliseconds, that determines how long the stream will attempt to write before timing out. (Inherited from Stream.)

Methods

	Name	Description
	BeginRead	Begins an asynchronous read. (Overrides FileStream.BeginRead(array<Byte[], Int32, Int32, AsyncCallback, Object).)
	BeginWrite	Begins an asynchronous write. (Overrides FileStream.BeginWrite(array<Byte[], Int32, Int32, AsyncCallback, Object).)
	Close	Closes the current stream and releases any resources (such as sockets and file handles) associated with the current stream. (Inherited from Stream.)
	CopyTo(Stream)	Reads all the bytes from the current stream and writes them to the destination stream. (Inherited from Stream.)
	CopyTo(Stream, Int32)	Reads all the bytes from the current stream and writes them to a destination stream, using a specified buffer size. (Inherited from Stream.)
	Dispose()	Releases all resources used by the Stream. (Inherited from Stream.)
	Dispose(Boolean)	Releases the unmanaged resources used by the IsolatedStorageFileStream and optionally releases the managed resources. (Overrides FileStream.Dispose(Boolean).)
	EndRead	Ends a pending asynchronous read request. (Overrides FileStream.EndRead(IAsyncResult).)
	EndWrite	Ends an asynchronous write. (Overrides FileStream.EndWrite(IAsyncResult).)
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Ensures that resources are freed and other cleanup operations are performed when the garbage collector reclaims the FileStream. (Inherited from FileStream.)
	Flush()	Updates the file with the current state of the buffer then clears the buffer. (Overrides FileStream.Flush().)
	Flush(Boolean)	Clears buffers for this stream and causes any buffered data to be written to the file, and also clears all intermediate file buffers. (Overrides FileStream.Flush(Boolean).)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Read	Copies bytes from the current buffered IsolatedStorageFileStream object to an array. (Overrides FileStream.Read(array<Byte[], Int32, Int32).)
	ReadByte	Reads a single byte from the IsolatedStorageFileStream object in isolated storage. (Overrides FileStream.ReadByte().)
	Seek	Sets the current position of this IsolatedStorageFileStream object to the specified value. (Overrides FileStream.Seek(Int64, SeekOrigin).)
	SetLength	Sets the length of this IsolatedStorageFileStream object to the specified value. (Overrides FileStream.SetLength(Int64).)
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	Write	Writes a block of bytes to the IsolatedStorageFileStream object using data read from a byte array. (Overrides FileStream.Write(array<Byte[], Int32, Int32).)
	WriteByte	Writes a single byte to the IsolatedStorageFileStream object. (Overrides FileStream.WriteByte(Byte).)

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.
