correlate

Hi all,

I have a IEnumerable. I have a custom Interval class which just has two DateTimes inside it. I want to convert the IEnumerable to IEnumerable where n DateTimes would enumerate to n-1 Intervals.

So if I had 1st Jan, 1st Feb and 1st Mar as the DateTime then I want two intervals out, 1st Jan/1st Feb and 1st Feb/1st March.

Is there an existing C# Linq function that does this. Something like the below Correlate...

IEnumerable<Interval> intervals = dttms.Correlate<DateTime, Interval>((dttm1, dttm2) => new Interval(dttm1, dttm2));

If not I'll just roll my own.

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy.
