Initializes a new instance of the IsolatedStorageFileStream class. The only way to open an IsolatedStorageFileStream is by using one of its constructors.

Overloads

IsolatedStorageFileStream(String, FileMode)

Initializes a new instance of an IsolatedStorageFileStream object giving access to the file designated by path in the specified mode.
IsolatedStorageFileStream(String, FileMode, FileAccess)

Initializes a new instance of the IsolatedStorageFileStream class giving access to the file designated by path, in the specified mode, with the kind of access requested.
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, FileShare)

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.
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, Int32)

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.
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.
IsolatedStorageFileStream(String, FileMode, FileAccess, FileShare, Int32, 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, with the buffersize specified, and in the context of the IsolatedStorageFile specified by isf.

IsolatedStorageFileStream(String, FileMode)

Source:
IsolatedStorageFileStream.cs
Source:
IsolatedStorageFileStream.cs
Source:
IsolatedStorageFileStream.cs

Initializes a new instance of an IsolatedStorageFileStream object giving access to the file designated by path in the specified mode.

public:
 IsolatedStorageFileStream(System::String ^ path, System::IO::FileMode mode);
public IsolatedStorageFileStream (string path, System.IO.FileMode mode);
new System.IO.IsolatedStorage.IsolatedStorageFileStream : string * System.IO.FileMode -> System.IO.IsolatedStorage.IsolatedStorageFileStream
Public Sub New (path As String, mode As FileMode)

Parameters

path
String

The relative path of the file within isolated storage.

mode
FileMode

One of the FileMode values.

Exceptions

ArgumentException

The path is badly formed.

ArgumentNullException

The path is null.

DirectoryNotFoundException

The directory in path does not exist.

FileNotFoundException

No file was found and the mode is set to Open

Remarks

The isolated store that is used is scoped by the current executing assembly's identity and that of the application domain in which it is running. This store will remain open only for the lifetime of the IsolatedStorageFileStream object. To specify a different isolated storage scope, or to allow the store to remain open (so multiple IsolatedStorageFileStream objects can be opened from it), use the form of the constructor that accepts an IsolatedStorageFile object.

The mode parameter indicates whether a new file should be created, an existing one used, and so on.

Caution

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.
