joining IEnumerables together

[cody]

Hi, I have multiple Collections which I want to iterate over *without*
copying alle my collections into one.

If there is no method to do this I propose a new Class Enumerate which
should provide something like that: IEnumerable Join(IEnumerabl e
a,IEnumerable b)

That's very easy to write - I suggest you try it and see how useful it
is for you.

Yes writing that kind of functionality is not a problem but it would be
great if the framework would provide such a thing, just because I don't like
always having to reinvent the wheel.

Re: joining IEnumerables together

In 2.0 this becomes trivial:

public IEnumerable<T> JoinTwoEnumerat ors(IEnumerable <T> first,
IEnumerable<T> second)
{
foreach (T t in first)
{
yield return t;
}

foreach (T t in second)
{
yield return t;
}
}
