Another C# trick: Fluents, Inheritance and Extension Methods (blogs.msdn.com)

submitted by crpietschmann(11.3k) 2 years, 3 months ago

Here’s a scenario which Damien and I encountered recently. We needed a way of specifying Facets for properties on Entities, i.e. things like Nullable, MaxLength, Precision etc. And we needed a class hierarchy because different types of properties have different sets of available facets. The base class of the hierarchy is called PropertyConfiguration which defines a series of Fluent methods that are shared by all sub types: read more...

A Handy Extension Method: Raise Events Safely(blogs.microsoft.co.il)

submitted by shayfriedman(1411) 2 years, 8 months ago

Raising events is a very common practice. We do that a lot and it’s pretty irritating to check for nullity every time. The simple extension methods I present in this post spare the need to repeat this practice every single time. read more...

.NET Utility Libraries Galore(hsidev.wordpress.com)

submitted by crpietschmann(11.3k) 3 years, 6 months ago

Yesterday Karl Seguin announced a new .NET Extension Library. One of the really interesting pieces of the library is a streamlined approach to a simple dictionary imagecache, which is similar to the one described in another interesting looking utility library called ShadeTree. Recently, Ayende Rahein reviewed another .NET utility library called Umbrella, which looks like a pretty wide and deep set of utilities. As I am about to create a new solution to consolidate the utility functionality we use across our various projects, it got me thinking it might be time to pick an established (or growing) library from the community and try to contribute any missing pieces we need for our own projects. read more...

C#: Enhance Enums using Extension Methods(pietschsoft.com)

submitted by crpietschmann(11.3k) 3 years, 6 months ago

Extension Methods are one of the coolest features that have been added in .NET 3.5. I've heard arguments that there is no reason to use them, and the only reason Microsoft added them is to enable the ability to buid LINQ. Well, I do not entirely agree with that statement; in fact, I have found a cool way to use Extension Methods to enhance the System.Enum object since it cannot be inherited. Even though Enum can not be inherited, it can be extended using Extension Methods. Here's the code to an Extension Method that extends the LocalizationMarket Enum with the ToDescriptionString() method that returns the DescriptionAttributes value for the given enum value. read more...

Useful Extension Method On String(deepakkapoor.net)

submitted by deepakkapoor(430) 3 years, 7 months ago

.NET Framework provides String.IsNullOrEmpty() method which return true if the string is null or empty. It does not however take care of a string which only contains spaces. Often while persisting data we do not want to persist just empty strings. In past I have made this check before I let my data pass through. Today I thought of creating an extension method to do the same for me. read more...

MVC: Creating SSL Links/URLs(squaredroot.com)

submitted by TroyMG(2670) 3 years, 7 months ago

A couple days ago a reader sent in a question regarding how to use SSL with the MVC framework. Specifically the reader wanted to know the easiest way to make an Ajax call to a HTTPS page from a non HTTPS page. The tricky part here is to do so without hard-coding any URLs, so I whipped up a few extension methods that should make this a bit easier. read more...
