title: Asp.NET temporary file saving
body: <p>I got a path from the jquery code <code>URL.createObjectURL(event.target.files[0]);</code></p>
  
  <p>It returns something like this : <code>blob:http%3A/localhost%3A59105/f7dae0f7-088f-48cf-b446-eeda0bf23705</code></p>
  
  <p>I tried to save this file like </p>
  
  <pre><code>byte[] data;
      using (WebClient client = new WebClient())
      {
          data = client.DownloadData("blob:http%3A/localhost%3A59105/f7dae0f7-088f-48cf-b446-eeda0bf23705");
      }
      File.WriteAllBytes(@"~/a.jpg", data);
  </code></pre>
  
  <p>But it gives an error about the code above:</p>
  
  <pre><code>  The URI prefix is not recognized.
  </code></pre>
  
  <p>How exactly I can copy this file?</p>
  
  <p>Thanks for your suggestions.</p>
