What are your favorite extension methods for C#? (codeplex.com/extensionoverflow)
...cause internally .Next(int) is made with .NextDouble() so you would save a cast, a * and a check.

In C++, what is a virtual base class?
...ve happened to any symbol (e.g. typedef, member variable, member function, cast to the base class, etc.). This really is a multiple inheritance issue, an issue that users should be aware to use multiple inheritance correctly, instead of going the Java way and conclude "Multiple inheritance is 100% e...
How do I use Linq to obtain a unique list of properties from a list of objects?

When taking Distinct we have to cast into IEnumerable too. If list is model means, need to write code like this
IEnumerable<T> ids = list.Select(x => x).Distinct();

some_strings = ('foo', 'bar', 'baz')
Let's roll our own list join method:
class OurList(list):
def j...
Comparing two byte arrays in .NET
...ner ! The previous solution was slightly more efficient since it saved the cast to IStructuralEquatable (an array is statically known to be IStructuralEquatable), but indeed your suggestions makes the method work for null arguments as well.
