title: Get Filestream from ZipArchive
body: <p>I have a function that requires a Filestream as input.</p>
  
  <p>I want to hand several Files to that function which I get from uploaded zip-Files.
  Is it possible to create the Filestream without extracting the file to a temporary folder?</p>
  
  <p>I imagin something like this:</p>
  
  <pre><code>string path = @"C:\somepathtomyzip";
  string filepath = "nameofimagefile"
  using (ZipArchive archive = ZipFile.OpenRead(path))
  {
      ZipArchiveEntry entry = archive.GetEntry(file_path);
  
      //generate Filestream from entry
  
      myFunction(filestreamIneed);
  }
  </code></pre>
