GitHub link for the project:
We will create a project in .NET Core using dotnet cli and will use visual studio code as the IDE.
Go to any directory where you want to create this project.
We are using powershell to setup this project.
PS E:/VSCODE/NETProjects>mkdir Automapper
PS E:/VSCODE/NETProjects>cd Automapper
Lets create a solution in Automapper folder.
PS E:/VSCODE/NETProjects>Automapper>dotnet new sln
Lets create a project in the Automapper folder.
PS E:/VSCODE/NETProjects>Automapper>dotnet new webapi -o Automapper.API
Lets add the project in the solution file because as of now they are disconnected to each other.
dotnet sln add Automapper.API/Automapper.API.csproj
Now lets open Automapper folder in vscode.
PS E:/VSCODE/NETProjects>Automapper>code .
Switch to project folder and install automapper.
PS E:/VSCODE/NETProjects>Automapper>cd Automapper.API
PS E:/VSCODE/NETProjects>Automapper>Automapper.API>dotnet add package AutoMapper.Extensions.Microsoft.DependencyInjection
We setup our project, now lets write some code. First of all delete the weather api controller and weather api class as we don't need this.
Lets create two folders Models and DTO.
Models will have classes that will exactly match with the database tables and DTO will have classes which need to pass to the client.
In our case we are using Employee class in Models folder and EmployeeDTO in DTO folders.
You can see that we are not passing employee salary to the client.
Now we will create profile which will map from Employee to EmployeeDTO.
Lets create a folder AutoMapperProfile in the project and add a class AutomapperProfile.cs.
Lets setup the ConfigureServices method of startup class for automapper.
Now lets create a EmployeeController in Controllers folder.
We are almost done with this, lets run this project and see the output.
PS E:/VSCODE/NETProjects>Automapper>Automapper.API>dotnet run
Type this url in the browser to view the output: https://localhost:5001/api/Employee
