LINQ

Suppose I have a list or array of items, and I want to sum a subset of the items in the list. (in my case, it happens to always be a sequential subset).

Here's the old-fashioned way:


int sum = 0;
for(int i = startIndex; i <= stopIndex; i++)
  sum += myList[i].TheValue;
return sum;

What's the best way to linqify that code?

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. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
