The How to: Delete Files and Directories in Isolated Storage example demonstrates the use of the DeleteDirectory method.
// This method deletes directories in the specified Isolated Storage, after first // deleting the files they contain. In this example, the Archive directory is deleted. // There should be no other directories in this Isolated Storage. void DeleteDirectories() { try { IsolatedStorageFile^ isoFile = IsolatedStorageFile::GetStore( static_cast<IsolatedStorageScope>(IsolatedStorageScope::User | IsolatedStorageScope::Assembly | IsolatedStorageScope::Domain), System::Security::Policy::Url::typeid, System::Security::Policy::Url::typeid ); array<String^>^dirNames = isoFile->GetDirectoryNames( "*" ); array<String^>^fileNames = isoFile->GetFileNames( "Archive\\*" ); // Delete the current files within the Archive directory. if ( fileNames->Length > 0 ) { for ( int i = 0; i < fileNames->Length; ++i ) { //delete files isoFile->DeleteFile( String::Concat("Archive\\", fileNames[ i ]) ); } fileNames = isoFile->GetFileNames( "Archive\\*" ); } if ( dirNames->Length > 0 ) { for ( int i = 0; i < dirNames->Length; ++i ) { // Delete the Archive directory. isoFile->DeleteDirectory( dirNames[ i ] ); } } dirNames = isoFile->GetDirectoryNames( "*" ); isoFile->Remove(); } catch ( Exception^ e ) { Console::WriteLine( e->ToString() ); } }
