# re: IsDate() function in C#

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

# re: IsDate() function in C#

Better with TryParse

DateTime dt;

return DateTime.TryParse(inputDate, out dt);

You could even make it an extension method for string!

# re: IsDate() function in C#

You might want to use a TryParse instead of a Parse. You'll avoid throwing an exception which causes perf issues.

says TryParse is slightly better.

I hear you should use TryParse.

# re: IsDate() function in C#

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.

# re: IsDate() function in C#

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.

Badly need your help. Nice site - pity you have to go to such lengths to moderate it. Help me! I can not find sites on the: Online brokerage firms stocks. I found only this - <a href="wai.alaw.org/.../online-brokerage-account-comparison">online brokerage account comparison</a>. Most of the fees will result you with a firm business given to your stock capital, and you can get your challenge from any of the value which improves the interest you have, online brokerage. You must start the rail to hold with their market, online brokerage. Waiting for a reply :confused:, Valora from Algeria.

Hello:

DateTime.TryParse does not give a SQL Date when we use "March 16 -17" which in SQL is invalid, but in C# it is march 16, 2017

# re: Tip 8 : IsDate() function in C#

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.

# re: Tip 8 : IsDate() function in C#

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".
