Empty strings

[Chris Capel]

Is there any way to express this more concisely?

if (someString == null || someString == "")
throw new ArgumentExcepti on("String must have something in it."); // or
something

What would be perfect would be someString.IsEm pty(), but MS didn't see fit
to include that particular one. Maybe there's something just as good. ??

It would have be a static method, something like String.IsEmptyO rNull(string
str)
because someString.IsEm pty() will throw a null reference exception if
someString is null.

As the MS guys did not provide it, you will have do it (we did). You just
have to write some kind of StringHelper class with this static method in it.

Chris,

You should probably change the ArgumentExcepti on to an
ArgumentNullExc eption, just to be more concise. Otherwise, I would do as
Bruno recommends, and create your own static method.

Re: Empty strings

He's also checking if string is zero-length - ArgumentNullExc eption does not
quite fit in that case.

Just FYI, if you try Whidbey Alpha, you will see String.IsNullOr Empty is
added in String class.
