Integrating C# with databases using Dapper ORM

How to Integrating Databases using Dapper ORM in C#

Dapper is a simple object mapper for .NET that simplifies accessing data stored in a database. It is a lightweight, fast, and easy-to-use alternative to Entity Framework and other ORMs (Object Relational Mappers).

One of the main advantages of Dapper is its performance. It is designed to be very fast and efficient, and can often execute queries faster than other ORMs. This makes it a good choice for applications where performance is critical, such as in high-traffic websites or applications that require real-time processing.

In addition to its performance, Dapper is also easy to use. It has a simple API that allows you to execute SQL queries and map the results to .NET objects with just a few lines of code. It also supports async/awaits for asynchronous programming.

Overall, Dapper is a powerful and flexible tool that can be a great addition to any .NET project that needs to access a database.

Dapper Integration

To use Dapper in a C# project, you will need to install the Dapper NuGet package. You can do this using the following steps:

  1. In your Visual Studio project, open the “Package Manager Console” from the “Tools” menu.
  2. In the Package Manager Console window, type the following command and press Enter: Install-Package Dapper
  3. This will install the Dapper package and all of its dependencies into your project.

Once the Dapper package is installed, you can use it in your C# code by including the following using statement at the top of your file:

using Dapper;

You can then use the extension methods provided by Dapper to execute queries and map the results to your objects. For example, you can use the Query method to execute a SELECT query and map the results to a list of objects:

using (IDbConnection connection = new SqlConnection(connectionString))
    var users = connection.Query<User>("SELECT * FROM Users WHERE Age > @Age", new { Age = 18 }).ToList();

This example uses the Query method to execute a SELECT query and map the results to a list of User objects. The @Age parameter in the query is replaced with the value of the Age property in the anonymous object passed as the second argument.

You can also use Dapper to execute INSERT, UPDATE, and DELETE statements, as well as stored procedures.
