问题 We have a few problems in a project I am working on, where we have a lot of JavaScript files, where we have hardcoded URLs to controller actions. Hardcoded URLs are proned to mistyping Hardcoded URLs in JavaScript scripts will cause a breakage if the related controller or action's name is changed Tools like ReSharper (to my knowledge) can't statically analyse it's way to saying the an action is not used, if the URLs pointing to it are hardcoded. Question(s) How can we avoid using hardcoded

问题 I am writing a service to take a collection of objects of a particular type and output its primitive, string, and DateTime types to a string in CSV Format. I have both of the below statements working. I find the the lambda based version to be much cleaner. Magic String Version string csv = new ToCsvService<DateTime>(objs) .Exclude("Minute") .ChangeName("Millisecond", "Milli") .Format("Date", "d") .ToCsv(); vs. Lambda Version string csv = new ToCsvService<DateTime>(objs) .Exclude(p => p.Minute

.Net - Strategies to avoid magic string

问题 In code at work, we have many uses of magic strings like the following code snippet: if (user.HasRight("Profile.View")) {...} So there are many places where we pass a string as a parameter to see if the user has a specific right. I don't like that because that generates a lot of magic strings. What would be a better way of doing it? Enum, Constant, class ? 回答1: In that specific case, use an Enum. There will be no magic strings and if the Enum changes (in a way that would break the magic

问题 I have a background in desktop software development and am getting started with learning ASP.NET MVC. In my default HomeController I have the Index action which has code that looks like this: if (!Request.IsAuthenticated) return RedirectToAction("Login", "Account"); In other words, redirect the user to "/account/login". The AccountController.Login action will then handle the user and send him back to the HomeController once he logs in successfully. This code smells to me, perhaps just because

Compile Time Reflection in C#

阅读更多关于 Compile Time Reflection in C#

I frequently write C# code that has to use magic strings to express property names. Everyone knows the problems with magic strings. They are very difficult to refactor, they have no compile time checking, and often they lead to hard-to-diagnose issues. Yet C#/.NET uses them all over the place to represent property/class/method names. This issue has persisted for years and years, and the only viable solution currently is to use an expression tree which is then parsed at run-time for the property name. This gets you satisfactory compile-time checking, but it complicates the code (requiring
