Within this part, we are going to create a simple repository sample. We’ll help it become straightforward since this post is about Dapper.
Following the course development, we could register it as being a singleton support from the Startup course, For anyone who is utilizing .NET5:
QueryMultiple – an extension method that executes a number of queries within the same command and maps final results
Working with the update and delete is really uncomplicated due to the fact we have already got many of the expected expertise. So, let’s bounce straight on the code.
We’ll use try out-catch blocks in Each individual motion in our controller for the example’s sake. But to prevent code repetition, we strongly suggest examining our International Mistake Dealing with post.
Dapper is made to be quickly, productive, and user friendly, which makes it a superb choice for developers who want To optimize performance and efficiency.
As you are able to see, there's nothing new Using these two methods. We have a query and parameters, and we execute our statements With all the ExecuteAsync strategy.

Whether you want to master World wide web development or application architecture you should Verify our Classes and decide on the one which you prefer.
It is amongst the speediest and most straightforward all-around, yet it's very extensible and, earlier mentioned all, effectively adopted and Employed in extremely significant-efficiency Web-sites. A lot more precisely is formulated and it is managed by the fellows behind StackOverflow, so that you can make certain it is battle-tested. Supply code is on GitHub
If you'd like to learn the way to produce a fully-fledged Repository Pattern, you'll be able to read through our short article on that matter. Also, yow will discover the async Variation of it if you want to write it that way.
Right here, we create our query as well as a dynamic parameters item (we're not working with an anonymous object any more). We populate that item with our 3 parameters after which you can get in touch with the ExecuteAsync method to execute our insert assertion.
Observe: If we skipped any matters Within this ASP.NET MVC Tutorial program, make sure you let us know by commenting in dapper tutorial for beginners the remark portion, and we unquestionably deal with All those matters right away.
