IsolatedStorageFileStream Constructor (String, FileMode)


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

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

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

public IsolatedStorageFileStream(
	string path,
	FileMode mode


Type: System.String

The relative path of the file within isolated storage.

Type: System.IO.FileMode

One of the FileMode values.

Exception Condition

The path is badly formed.


The path is null.


The directory in path does not exist.


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, an existing one used, and so on.


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.
