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, with the buffersize specified, and in the context of the IsolatedStorageFile specified by isf.

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

Public Sub New (
	path As String,
	mode As FileMode,
	access As FileAccess,
	share As FileShare,
	bufferSize As Integer,
	isf As IsolatedStorageFile


Type: System.String

The relative path of the file within isolated storage.

Type: System.IO.FileMode

One of the FileMode values.

Type: System.IO.FileAccess

A bitwise combination of the FileAccess values.

Type: System.IO.FileShare

Type: System.Int32

The FileStream buffer size.

Type: System.IO.IsolatedStorage.IsolatedStorageFile

The IsolatedStorageFile in which to open the IsolatedStorageFileStream.

Exception Condition

The path is badly formed.


The path is null.

isf does not have a quota.

The mode parameter indicates whether a new file should be created or an existing one used. The access parameter includes read-only, read/write, and write-only.


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.

' Open or create a writable file with a maximum size of 10K.
Dim isoStream As New IsolatedStorageFileStream(Me.userName, FileMode.OpenOrCreate, _
    FileAccess.Write, FileShare.Write, 10240, isoFile)
