Dapper in MVC

How to use Dapper ORM in C#

Introduction

In theĀ previous article, you have learned about what is ViewBag , ViewData, and TempData, their scope, and how to use it in the MVC application.

In this article, you will learn how to map the database data to the model and display it in a view with Dapper Micro ORM.

This article will be helpful to beginners and students who are learning MVC. 

What is Dapper

Basically, Dapper is a micro ORM , It is a simple object mapper framework that helps to map the database query output to the domain class. It’s a open source and high perfomance system.

It extends the IDbConnection interface. The IDbConnection interface represents an open connection to data source implemented by the .NET framework.

If your MVC app contains store procedure or native query instead of using ORM tool like entity-framework, then it’s preferable to use the Micro ORM like dapper.

Pre-Requisites

  • You need to create ASP.NET MVC Project(You can refer our Create Asp .Net MVC application article for that), Or you can add this into the existing project also A SQL  server Installed where you can create a database.
  • A Database created on the SQL server. 

Implementation

Step 1:

In the project add the nu-get package named “Dapper”. To install Dapper open a package manager and run the below code, it will take a few seconds to install.

Step 2:

Create a model class that has the exact same property as the database. In our case replace the below-given code.

User.cs

Step 3:

Add the below code to the method that returns the list of data from database to the view,

Here we have index method from Home controller which returns the data of user table in the view page of the Index action that Index.cshtml

Add the below given code of the Index.cshtml and Index action of Home.cs

In Index action we are using IDbConnection to connect to the database, and we are fetching data from the Users table.

Home.cs

Index.cshtml

And when you the code it will display the records of User table as shown below in the browser.
