IsolatedStorageFileStream Constructor (String, FileMode, FileAccess)

IsolatedStorageFileStream Constructor (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.

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

public IsolatedStorageFileStream(
	string path,
	FileMode mode,
	FileAccess access


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.

Exception Condition

The path is badly formed.


The path is null.


No file was found and the mode is set to Open.

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 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.
