IsolatedStorageFileStream Constructor (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.

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

public IsolatedStorageFileStream(
	string path,
	FileMode mode,
	FileAccess access,
	FileShare share
)

Parameters

path
Type: System.String

The relative path of the file within isolated storage.

mode
Type: System.IO.FileMode

One of the FileMode values.

access
Type: System.IO.FileAccess

A bitwise combination of the FileAccess values.

share
Type: System.IO.FileShare

A bitwise combination of the FileShare values.

ExceptionCondition
ArgumentException

The path is badly formed.

ArgumentNullException

The path is null.

FileNotFoundException

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.

Caution noteCaution

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.


// Retrieve an IsolatedStorageFile for the current Domain and Assembly.
IsolatedStorageFile isoFile =
    IsolatedStorageFile.GetStore(IsolatedStorageScope.User |
    IsolatedStorageScope.Assembly |
    IsolatedStorageScope.Domain,
    null,
    null);

IsolatedStorageFileStream isoStream =
    new IsolatedStorageFileStream("substituteUsername",
    System.IO.FileMode.Open,
    System.IO.FileAccess.Read,
     System.IO.FileShare.Read);
