Greetings!

I have this code,

First option...

foreach (...)
{

  if (std.string.tolower(fext[0]) == "doc" ||
    std.string.tolower(fext[0]) == "docx" ||
    std.string.tolower(fext[0]) == "xls" ||
    std.string.tolower(fext[0]) == "xlsx" ||
    std.string.tolower(fext[0]) == "ppt" ||
    std.string.tolower(fext[0]) == "pptx")
   continue;
}

Second option...
foreach (...)
{
  if (std.string.tolower(fext[0]) == "doc")
    continue;
  if (std.string.tolower(fext[0]) == "docx")
    continue;
  if (std.string.tolower(fext[0]) == "xls")
    continue;
  if (std.string.tolower(fext[0]) == "xlsx")
    continue;
  if (std.string.tolower(fext[0]) == "ppt")
    continue;
  if (std.string.tolower(fext[0]) == "pptx")
   continue;
  ...
  ...
}

So, after I saw this post I asked myself, what?  So, the question 
is: which of the two foreach loops options are faster:
1. The concatenated if ||
2. The single if

I am trying to see if it matters.  I have a project with lots of 
files and if one is faster, then, it will matter to code it the 
faster way.  Thanks.
