Sorry for being lazy but where's IEnumerable.OrderBy declared. I know it's an extension method but where, in which class is it declared?

I have the following methods:
public <T> T fromJson( Reader jsonData, Class<T> clazz ) {
return fromJson( jsonData, (Type)clazz );
}
public <T> T fromJson( Reader jsonData, Type clazz ) {
...
}
The compiler is saying about the first method:
type parameters of <T>T…

I'm trying to make use of the TheoryAttribute, introduced in NUnit 2.5. Everything works fine as long as the arguments are of a defined type:
[Datapoint]
public double[,] Array2X2 = new double[,] { { 1, 0 }, { 0, 1 } };
[Theory]
public void TestForArbitraryArray(double[,] array)
{
// ...
}

I would like to create an object of Generics Type in java. Please suggest how can I achieve the same.

This question might seem trivial and also stupid at the first glance, but it is much more than this.
I have an array of any type T (T[]) and I want to convert it into a List generic (List<T>). Is there any other way apart from creating a Generic list, traversing the whole array and adding the…

I'm hashing a file with one or more hash algorithms. When I tried to parametrize which hash types I want, it got a lot messier than I was hoping.
I think I'm missing a chance to make better use of generics or LINQ. I also don't like that I have to use a Type[] as the parameter instead of limiting…

I'd like to create a lot of extension methods for some generic class, e.g. for
public class SimpleLinkedList<T> where T:IComparable
And I've started creating methods like this:
public static class LinkedListExtensions
{
public static T[] ToArray<T>(this SimpleLinkedList<T>…

I just gave an answer to a quite simple question by using an extension method. But after writing it down i remembered that you can't unsubscribe a lambda from an event handler.
So far no big problem. But how does all this behave within an extension method??
Below is my code snipped again. So can…

I'm working with a device that sends back an image, and when I request an image, there is some undocumented information that comes before the image data. I was only able to realize this by looking through the binary data and identifying the image header information inside.
I've been able to make…

Not that anyone would still need this, but in case you have a situation where the code MUST be .NET 2.0 compliant and you want to use a cool feature like Extension methods, there is a way.
I saw this article when looking for ways to create extension methods in C++, C# and VB:

edit4: wikified, since this seems to have morphed more into a discussion than a specific question.
In C++ programming, it's generally considered good practice to "prefer non-member non-friend functions" instead of instance methods. This has been recommended by Scott Meyers in this classic Dr. Dobbs…
