Tip 8 : IsDate() function in C#

• Might be better off using DateTime.TryParse. Could be faster than throwing an exception.
  

• Better with TryParse
  
  DateTime dt;
  return DateTime.TryParse(inputDate, out dt);
  
  You could even make it an extension method for string!
  

• I hear you should use TryParse.
  

• I agree with the comments for a TryParse, you could also make use of the 3.5 extension feature
  

• Hi.
  I'm a little skeptical about this method. Because probably if it's a date you will need the value of the data so once again you will parse the date.
  I'm sorry but your method is useless to me.
  Just my 2 cents.
  

• I would prefer it without a try catch
  
  DateTime dt = DateTime.Now;
  return DateTime.TryParse(inputDate, dt);
  

• This is a nice post. However, I think it should be edited to take into account the nice comments/feedback.
  

• Don't you love it when someone writes a "helpful" article using 10 lines of wasteful code... when there alread IS a built-in method using 1 line of code?
  
  I wonder how many people just read the article... and use the bad code... and never wade through all the "corrections" below it.
  
  Sure would be nice if the original author would admit: "I made a mistake! Just use TryParse instead of my mess!" and remove his code.
  
  
  

• But he DID post the "alternate" method.
  
  (It really shouldn't be "alternate"... it should be *THE* method you use.)
  
  The 2 code samples are now implied as "correct method" and "alternate method".
  
  They really should be cleary marked "bad example" and "use this always".
