IsolatedStorageFileStream Constructor (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.
Assembly: mscorlib (in mscorlib.dll)
public:
IsolatedStorageFileStream(
String^ path,
FileMode mode,
FileAccess access,
FileShare share,
IsolatedStorageFile^ isf
)
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.
- isf
-
Type:
System.IO.IsolatedStorage::IsolatedStorageFile^
The IsolatedStorageFile in which to open the IsolatedStorageFileStream.
| Exception | Condition |
|---|---|
| ArgumentException | The path is badly formed. |
| ArgumentNullException | The path is null. |
| FileNotFoundException | No file was found and the mode is set to Open. |

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.
// This is the stream to which data will be written. IsolatedStorageFileStream^ source = gcnew IsolatedStorageFileStream( this->userName,FileMode::OpenOrCreate,isoFile ); // This is the stream from which data will be read. Console::WriteLine( "Is the source file readable? {0}", (source->CanRead ? (String^)"true" : "false") ); Console::WriteLine( "Creating new IsolatedStorageFileStream for Archive." ); // Open or create a writable file. IsolatedStorageFileStream^ target = gcnew IsolatedStorageFileStream( String::Concat("Archive\\",this->userName),FileMode::OpenOrCreate,FileAccess::Write,FileShare::Write,isoFile );
