Can I collapse foreach, using and other c# code blocks in Visual Studio 2010?

Can I collapse foreach, using and other c# code blocks in Visual Studio 2010, the same way that I can collapse methods, properties, classes, namespaces, etc? It would be very he开发者_运维问答lpful sometimes.

You can use #region #endregion directives to create collapsible areas.

Update:

By the way, why do you need this functionality? There's a good principle to keep your methods as short as possible (Uncle Bob calls it extract until you drop). If you stick to it you won't need additional collapsible areas.

Cut + paste the code out of the foreach loop and into a function, collapse the function away?

E.g.,

public void MyMessyFunction()
{
  // ...

  foreach(string foo in bar)
  {
    // Do ugly stuff
  }

  // ...
}

Turns into

public void MyMessyFunction()
{
  // ...

  foreach(string foo in bar)
  {
    DoUglyStuff(foo, bar);
  }

  // ...
}

#region Stuff I want to hide

public void DoUglyStuff(string foo, List<string> bar)
{
  // Do ugly stuff
}

#endregion

As I recall, you can collapse an arbitrary region in Visual Studio 2010. Try selecting a region, then press Ctrl+M twice (assuming C# key bindings).

In VS2008, this is found under Edit -> Outlining; I don't have a 2010 installed so can't try it out there readily.

Edit: Actually, it looks like VS2008 has something similar in its "Hide Selection" feature (found in the same place), but it appears to only be available in some languages.
