Term for "find, remove and return an element" in a set?

Question

Title says it mostly. I want to add a simple extension method to the base Dictionary class in C#. At first I was going to name it Pop(TKey key), kind of like the Stack method, but it accepts a key to use for lookup.

Then I was going to do Take(TKey key), but it coincides with the LINQ method of the same name...and although C# 3.0 lets you do it, I don't like it.

So, what do you think, just stick with Pop or is there a better term for "find and remove an element"?

(I feel kind of embarrassed to ask this question, it seems like such a trivial matter... but I like to use standards and I don't have wide experience with many languages/environments.)

EDIT: Sorry, should have explained more.... In this instance I can't use the term Remove since it's already defined by the class that I'm extending with a new method.

EDIT 2: Okay, here's what I have so far, inspired by the wisdom of the crowd as it were:

public static TValue Extract<TKey, TValue>
(
    this Dictionary<TKey, TValue> dict,
    TKey key
)
{
    TValue value = dict[key];
    dict.Remove(key);
    return value;
}

public static bool TryExtract<TKey, TValue>
(
    this Dictionary<TKey, TValue> dict,
    TKey key,
    out TValue value
)
{
 if( !dict.TryGetValue(key, out value) )
 {
  return false;
 }
 dict.Remove(key);
 return true;
}

Answer 1

anything in particular wrong with the Remove(key) method already provided?

oh wait, you want to return the element removed also? how about

object valueRemoved = someDictionary.RemoveElement(key)

easily implemented as

if (!dict.ContainsKey(key))
{
    return null;
}
object val = dict[key];
dict.Remove(key);
return val;

Answer 2

My first guess would have been "Take", but as you pointed out, that is already taken. My next suggestions would be "Extract" or "Detach", but they may be ambiguous.

How about "Withdraw" or "PullOut"?

Answer 3

I reckon Extract, like when archaeologists Find a mummy in the ground, Remove it and then Return it to a museum :)

Answer 4

This action is slightly reminiscent of an old collaboration platform (mainly academic) called Linda. In that environment, what you're talking about would be called "in". But that's a terrible name for it - they basically had the names backwards because they named them from the point of view of the shared tuple space. So, nevermind.

Extract is good, and "Pop" is also pretty obvious (just about anyone would know what you were doing, even though it's not a stack).
