IsolatedStorageFileStream Constructor (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.
Assembly: mscorlib (in mscorlib.dll)
Public Sub New ( path As String, mode As FileMode, access As FileAccess, isf As IsolatedStorageFile )
The relative path of the file within isolated storage.
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.
Dim isoFile As IsolatedStorageFile isoFile = IsolatedStorageFile.GetUserStoreForDomain() ' Open or create a writable file. Dim isoStream As New IsolatedStorageFileStream(Me.userName, FileMode.OpenOrCreate, _ FileAccess.Write, isoFile) Dim writer As New StreamWriter(isoStream) writer.WriteLine(Me.NewsUrl) writer.WriteLine(Me.SportsUrl) ' Calculate the amount of space used to record the user's preferences. Dim d As Double = Convert.ToDouble(isoFile.CurrentSize) / Convert.ToDouble(isoFile.MaximumSize) Console.WriteLine(("CurrentSize = " & isoFile.CurrentSize.ToString())) Console.WriteLine(("MaximumSize = " & isoFile.MaximumSize.ToString())) ' StreamWriter.Close implicitly closes isoStream. writer.Close() isoFile.Dispose() isoFile.Close() Return d
