I'm trying to declare a constant value for a hexdecimal value but it seems I can't achieve this in C#.
const PROCESSES = &H1F0FFF;
Why is this not working?
const int PROCESSES = 0x1F0FFF;

C#'s string already implements IEnumerable, and it has an indexer and a well-defined length, so why not support the new interface?
is it lack of time, or was the decision made for other reasons?

I need to put a code using C#. Need to could number of days once by using 2 dateTimePicker controls.
Anyone has any idea? I know how to do it in vb.net not sure how to do in C#.
vb.net code:
NumberOfDays = DateDiff(DateInterval.Day, CDate(StartDateTimePicker.Text),
CDate(EndDateTimePicker.Text))
int NumberOfDays = (StartDateTimePicker.Value - EndDateTimePicker.Value).Days;
Or if you want to account for partial days:
double NumberOfDays;
NumberOfDays = (StartDateTimePicker.Value - EndDateTimePicker.Value).TotalDays;
var numberOfDays = (EndDateTimePicker.Value - StartDateTimePicker.Value).TotalDays;

We've written a basic networking application using C# and .net. For tests, we'd love to use something similar to Ruby's VCR. Does such a thing exist for C#/.net ?

I am planning to write a LINQ provider, so that I can query data in a custom store - for example, let us say, some custom file format.
What is a good way to start? Any examples?
