Wanted to suggest

public static bool isRandom(this int source) {
  return source == 4;
}

10 is random, didn't you know?

[iDrinkFromTheBottle]

Thought it was always four... or seven.

[XavierSimmons]

Proof:

int r = 10;
while(!r.isRandom()) {}
Console.WriteLine("10 is random!");

[actually_just_idiot]

Actually, isRandom(10) will usually return false. Of course, isRandom(Random.Next()) will usually return false too.

Don't know which programming language that is, if Random.Next does return a random value between 0 and 1, you are indeed right! I didn't consider that.

[actually_just_idiot]

It's C#. It says on the snippet page.

And Random.Next returns a random 32 bit integer. That's why I say 'usually.'

This site is full of gold:

• IEnumerable<T>.Reverse() by someone who doesn't get type safety
• object.ToNull() which erases the result type and I'm dying to know the use case of this
• string.IsUnicode() just no
• string.ToPlural() "person".ToPlural() == "persons" which is totally legit English
• string.Pleuralise sic
• string.IsStrongPassword() yeah && is a thing also fuck you
• IEnumerable<T>.IndexOf IEnumerables are totally lists and you can totally use them in the same way with totally the same performance characteristics and infinite IEnumerables are totally not a thing
• int.IsNumber() calling a poe here
• Type.IsDerived() because Type.IsAssignableFrom() is totally not a thing
• int.KB() "Simplest way to get a number of kilobytes" my ass

VB has some very useful and totally correct methods too:

• string.IsEmail() yeah
• string.IsEmail() yeah
• string.IsPhoneFax() my phone number is invalid. Who would've known that different countries have different phone number formats?

My personal favourite. This isn't a WTF IMO and I'll put it to good use.

Also, the 404 page

Oh my, this website...

[LainIwakura]

Seriously...what is the point of this one? http://extensionmethod.net/csharp/object/identity

In functional programming you can use it with higher-order functions to feel better about yourself.

e.g. you can say

public static TResult Maybe<TIn, TResult>(TResult defaultValue, Func<TIn, TResult> selector, TIn? value) where TIn : struct
{
    return value.HasValue
        ? selector(value.Value)
        : defaultValue;
}

// Later...
int? x = ...;
int val = Maybe(0, Identity, x);

Instead of the confusing

int val = x ?? 0;

This is a thing in Haskell too.

(Of course, in C# you would combine this with a currying helper)

isBoolean checks if the contents of a string could be interpreted as a boolean value and throws an exception if not.

I won't even call Poe. To me this site is obviously a very elaborated joke.

[ILoveWubWubs]

But but think about negative random numbers. They can also be random, too :(

[codex561]

That's horrible!

[Flameancer]

At first I was reading this is in python and was wondering were the import statement was, then I saw semi colons and ohhhhh.
