How do I use DTOs in ASP.NET?

DTOs, or Data Transfer Objects, are used to transfer data between layers in an application. In ASP.NET, you can create a DTO class that represents the data structure you want to send or receive.

Can you give me an example of a DTO in ASP.NET?

Sure! Here's a simple example:

public class UserDto {
    public int Id { get; set; }
    public string Name { get; set; }
    public string Email { get; set; }
}

This DTO can be used to transfer user data between your API and the client.

How do I map my DTO to an entity model?

You can use libraries like AutoMapper to map DTOs to entity models easily. For example:

var userEntity = _mapper.Map<UserEntity>(userDto);

This will create a new UserEntity object from your UserDto.

What are the benefits of using DTOs?

DTOs help in reducing the amount of data sent over the network, improve performance, and provide a clear contract for data exchange between layers.
