.Net Tips — Use LINQ to create pairs of adjacent elements from a collection

Suppose you have an array of numbers, say, [1, 3, 5, 7, 9, …], and you want to pair each element up with its neighbour in the array, e.g. [[1, 3], [3, 5], [5, 7], [7, 9], …].

S3 — Use using block to get the stream

When you’re using the Amazon S3 client, have you come across the occasional exception that says something like one of these exception messages:

“The request was aborted: The connection was closed unexpectedly”

.Net Tips — Use LINQ to avoid nested loops

Admit it, we’ve all done it before, writing those nasty nested loops just so we can iterate through multiple lists to get some combination/permutation of the lists, e.g.:

1: for (int i = 0; i < 10; i++)

.Net Tips — Make sure the runtime types match when combining delegates

In C#, it’s possible to combine two delegates, A and B to create a new multicast delegate, C:

Extension Methods — Helpful parse methods for string

1: /// <summary>

2: /// Parses a string as a short

3: /// </summary>

4: public static short ParseShort(this string str, bool throwOnOverflow = true)

Mind the runtime optimization

You might know this already, but in C# whenever you write something like this:

1: if (MethodA() || MethodB())

2: {

3:     // do something

4: }

.Net Tips — Find out if your app is running as a service

When you are developing an application to run as a service it’s nice to be able to also run it as a console app so you can easily debug, etc. On the rare occasion you might even want to find out if your app is running in a console…
