If we should fail?

Lady Macbeth:

We fail?

But screw your courage to the sticking place,

And we'll not fail.

Sticking Place is yet another "junk drawer" C# library of useful extensions and helpers.

Helpers for ADO.NET/SQL

• SqlExceptionHelper: Create SqlException objects with whatever message and error number you'd like. See SqlExceptionHelperTests for more information. This should only be used for testing, I can't think of a good reason to use it otherwise.

Helpers for ASP.NET / ASP.NET MVC

• HttpExtensions::SetAuthCookie: On the surface, it seems like Forms Auth only lets you put a string (username) into the auth cookie. You can put arbitrary objects in there, but you have to jump through some extra hoops to do it. SetAuthCookie jumps through the hoops.
• HttpExtensions::GetAuthCookie: Get the arbitrary object back out of the Forms Auth cookie without all the hoop jumping.
• ModelStateDictionaryExtensions::GetAllErrors: A convenience extension to walk through the whole MVC ModelState errors tree. Good for unit testing sometimes too.
• HtmlHelperExtensions::ActionImage: A link with an image in it. You can specify routevalue and don't forget the alt!
• HtmlHelperExtensions::IsSelected: In an ASP.NET View layout page, I will often have a bunch of nav links that need to be highlighted when the controller is "active". For instance, on a menu I have 3 links: "Home", "Invoices", "Locations", each going to an action in their respective controllers. When an action in the "Users" controller is executed, I want the "Users" link to be visually highlighted by putting a CSS class on the link. To make this easy, I'll use the IsSelected extension like below. ReSharper and/or Visual Studio may not be happy with it, but it's valid Razor. It assumes a default CSS class of "active", but you can pass in another one.

<ul class="nav navbar-nav">
    <li@(@Html.IsSelected("Home"))>@Html.ActionLink("Home", "Index", "Home")</li>` 
    <li@(@Html.IsSelected("Invoices"))>@Html.ActionLink("Invoices", "Index", "Invoices")</li>
    <li@(@Html.IsSelected("Locations"))>@Html.ActionLink("Locations", "Index", "Locations")</li>
</ul>

• HtmlHelperExtensions::StateDropDownListFor, ProvicesDropDownListFor, TerritoriesDropDownListFor, StatesAndTerritoriesDropDownListFor, StatesAndProvincesDropDownListFor, StatesAndProvincesAndTerritoriesDropDownListFor: MVC Helpers to show dropdowns for U.S. States, Canadian provinces, and U.S. territories, and various permuations. Otherwise, it works just like Html.DropDownListFor. No offense intended to Canadians.
• StatesProvincesTerritories: This is the source data used for all of the above, broken up into States (which included Washington D.C.), Provinces, and Territories.

Helpers for string manipulation

• StringExtensions::ToMD5: Hash a string to an MD5 string. You should probably not be using MD5 for anything involving important, but for legacy/conversion reasons you may need to have this handy.
• StringExtensions::ToSHA256: Hash a string to an SHA256 string (lowercase, no spaces or dashes).

Helpers for Linq providers (e.g. for OR/Ms)

• IQueryableExtensions::OrderBy: Order a collection by a fieldname, specified by a string (ascending)
• IQueryableExtensions::OrderByDescending: Order a collection by a fieldname, specified by a string (descending)
• PredicateBuilder: A fluent way to build predicates using AND and (especially) OR that isn't supported by normal Linq extensions.

• There is a really hacky unit test for Html::ActionImage that I only mostly understand. It could use improvement. Unit test organization in general could use some improvement.
• I have some other mocking helpers that I use frequently with Telerik JustMock, but they aren't general enough (yet) to put in here.
