Question

I had this code in a project in VS2010 – it was a placeholder method I hadn’t fully implemented yet. I started the implementation today. Notice there are no {} surrounding the if/else for the while statement. This compiled many times – it has been that way for quite some time. Is this a bug in VS? I thought loops all needed {}

private void ParsefCIPProfiles(string block)
{
 StringReader reader = new StringReader(block);
 string readline = reader.readline();

 while (readline != null)
  if ()
  {}
  else
  {}
}

No, it isn’t a bug. In fact for single-statement contents, most other scoped statements also don’t require the curly braces. For instance:

//This is valid
using (var f = new foo)
    f.Bar();

// So is this
foreach (var i in someInts)
    Console.Out.WriteLine(i);
