作法：刪除隔離儲存區中的存放區
IsolatedStorageFile 類別提供兩種方法來刪除隔離儲存區檔案：
執行個體方法 Remove() 不接受任何引數，並刪除呼叫它的存放區。 這個作業不需要使用權限。 能夠存取存放區的任何程式碼，都可以刪除在它之內的任何或所有資料。
靜態方法 Remove(IsolatedStorageScope) 會接受 User 列舉值，並刪除執行程式碼之使用者的所有存放區。 這項作業需要 IsolatedStorageFilePermission 值的 AdministerIsolatedStorageByUser 權限。
範例
下列程式碼範例將示範靜態及執行個體 Remove 方法的使用方式。 該類別取得兩個存放區，一個為使用者和組件所隔離，而另一個為使用者、定義域和組件所隔離。 接著呼叫隔離儲存區檔案 Remove() 的 isoStore1方法，刪除使用者、定義域和組件存放區。 然後，使用者所有剩下的存放區是以呼叫靜態方法 Remove(IsolatedStorageScope)的方式刪除。
