在獨立存儲中存儲項目文件夾

Question

我正在一個名爲「webapplication」的文件夾中創建一個帶有靜態html文件的windows phone項目。我想將「webapplication」文件夾的所有內容存儲在獨立存儲中。有人可以幫助解決這個問題嗎？

要創建一個文件夾，請執行以下操作：

IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication(); 
myIsolatedStorage.CreateDirectory("NewFolder"); 

如果你想創建該文件夾中的文件，然後：

IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication(); 
StreamWriter writeFile = new StreamWriter(new IsolatedStorageFileStream("NewFolder\\SomeFile.txt", FileMode.CreateNew, myIsolatedStorage)); 

如果您正在尋找將文件複製到IsolatedStorage，然後您需要在第一次執行應用程序時運行以下代碼：

using (IsolatedStorageFile storage = IsolatedStorageFile.GetUserStoreForApplication()) 
      { 
       string[] files = System.IO.Directory.GetFiles(folderPath); 
       foreach (var _fileName in files) 
       { 
        if (!storage.FileExists(_fileName)) 
        { 
         string _filePath = _fileName; 
         StreamResourceInfo resource = Application.GetResourceStream(new Uri(_filePath, UriKind.Relative)); 
         using (IsolatedStorageFileStream file = storage.CreateFile("NewFolder\\SomeFile.txt", FileMode.CreateNew, Storage)) 
         { 
          int chunkSize = 102400; 
          byte[] bytes = new byte[chunkSize]; 
          int byteCount; 

          while ((byteCount = resource.Stream.Read(bytes, 0, chunkSize)) > 0) 
          { 
           file.Write(bytes, 0, byteCount); 
          } 
         } 
        } 
       } 
      }
