ASP.NET MVC Controller Action Precondition Filter (blog.troyd.net)

submitted by powerrushpowerrush(3873) 4 years ago

Here is code that will allow you to decorate your MVC Actions with attributes that will define your needed "preconditions". I often find the need to check for the existence of a parameter passed to a web page, such as an ID, and also often need to check if the ID is valid as well (e.g.: a valid primary key). These, I consider "preconditions".

As Phil Haack pointed out in the comments, I forgot to mention Postconditions as well:

"By the way, you can also do PostConditions this way too with action filters as we have an OnActionExecuted method that runs before we execute the result."
