从 Silverlight 中的isolatedStorage读取二进制数据

发布于 2024-09-29 19:14:22 字数 495 浏览 2 评论 0原文

我将一些字节写入了 Silverlight 应用程序中独立存储中的文件中。该文件名为“data.dat”。我使用以下代码将其写入隔离存储：

// Store the data in isolated storage
var bytes = GetData();
using (IsolatedStorageFile storage = IsolatedStorageFile.GetUserStoreForApplication())
{
  using (IsolatedStorageFileStream file = new IsolatedStorageFileStream("data.dat", FileMode.Create, storage))
  {
    file.Write(bytes, 0, bytes.Length);
  }
}

我的问题是，一旦字节存在，如何从隔离存储中检索字节？我看到的所有内容都会返回一个字符串。但我没有看到返回二进制数据的方法。

谢谢。

I have some bytes written to a file in isolated storage in my Silverlight application. This file is named "data.dat". I wrote it to Isolated Storage using the following code:

// Store the data in isolated storage
var bytes = GetData();
using (IsolatedStorageFile storage = IsolatedStorageFile.GetUserStoreForApplication())
{
  using (IsolatedStorageFileStream file = new IsolatedStorageFileStream("data.dat", FileMode.Create, storage))
  {
    file.Write(bytes, 0, bytes.Length);
  }
}

My question is, how do I retrieve the bytes from isolated storage once they're there? Everything I see returns a string. But I don't see a way to return binary data.

Thanks.

这段代码将检索字节 -

byte[] output;

using (IsolatedStorageFile isolatedStorageFile = IsolatedStorageFile.GetUserStoreForApplication())
{
   IsolatedStorageFileStream isolatedStorageFileStream = isolatedStorageFile.OpenFile("data.dat", FileMode.Open, FileAccess.Read);

   output = new byte[isolatedStorageFileStream.Length];
   isolatedStorageFileStream.Read(output, 0, output.Length);
   isolatedStorageFileStream.Dispose();
}

This piece of code will retrieve the bytes -

byte[] output;

using (IsolatedStorageFile isolatedStorageFile = IsolatedStorageFile.GetUserStoreForApplication())
{
   IsolatedStorageFileStream isolatedStorageFileStream = isolatedStorageFile.OpenFile("data.dat", FileMode.Open, FileAccess.Read);

   output = new byte[isolatedStorageFileStream.Length];
   isolatedStorageFileStream.Read(output, 0, output.Length);
   isolatedStorageFileStream.Dispose();
}
