IsolatedStorageFile::Dispose Method ()
Releases all resources used by the IsolatedStorageFile.
Assembly: mscorlib (in mscorlib.dll)
Call Dispose when you are finished using the IsolatedStorageFile. The Dispose method leaves the IsolatedStorageFile in an unusable state. After calling Dispose, you must release all references to the IsolatedStorageFile so the garbage collector can reclaim the memory that IsolatedStorageFile was occupying.
 Note |
|---|
Always call Dispose before you release your last reference to the IsolatedStorageFile. Otherwise, the resources the IsolatedStorageFileStream is using will not be freed until garbage collection calls the IsolatedStorageFileStream object's Finalize method. |
The following code example opens an isolated storage file, uses it to write information to a stream, closes the file, and then uses the Dispose method to release all resources.
IsolatedStorageFile^ isoFile; isoFile = IsolatedStorageFile::GetUserStoreForDomain(); // Open or create a writable file. IsolatedStorageFileStream^ isoStream = gcnew IsolatedStorageFileStream( this->userName,FileMode::OpenOrCreate,FileAccess::Write,isoFile ); StreamWriter^ writer = gcnew StreamWriter( isoStream ); writer->WriteLine( this->NewsUrl ); writer->WriteLine( this->SportsUrl ); // Calculate the amount of space used to record the user's preferences. double d = isoFile->CurrentSize / isoFile->MaximumSize; Console::WriteLine( "CurrentSize = {0}", isoFile->CurrentSize.ToString() ); Console::WriteLine( "MaximumSize = {0}", isoFile->MaximumSize.ToString() ); writer->Close(); isoFile->Close(); isoStream->Close(); return d;
when invoked late-bound through mechanisms such as Type::InvokeMember. Associated enumeration: ReflectionPermissionFlag::MemberAccess
