<p>Whats the best/easiest way to obtain a count of items within an IEnumerable collection without enumerating over all of the items in the collection?</p>

<p>Possible with LINQ or Lambda?</p>

In any case, you have to loop through it. Linq offers the
```
Count
```
method:
```
```
var result = myenum.Count();
```
```
