AutoMapper 正如前文说的那样,对象映射就是将一个对象中的属性按照一定规则映射到另一个对象中。这个操作是枯燥重复的,所以就有了 AutoMapper 这样的对象映射器。 映射规则 目标对象属性必须匹配源对象的属性,除非你对一个新属性进行了自定义; 在使用对象映射前,必须先配置映射关系; 映射.

Where I want to use subqueries to limit the objects returned, I can combine the SQL-based syntax with the method-based syntax by calling the Where method on the collection in my From clause, as in this example: var CanadaCustomers = from c in db.Customers.Where(cust => cust.region == "Canada") select new {c.custId, c.name};.

AutoMapper uses reflection to look at the properties of the source and destination classes (in the example above, the source class is the Team entity and the destination class is the TeamDTO data transfer object). For any property with the same name and type that occurs in both classes, a map definition is created that specifies that the value. . . The AddTransform method modifies the <Transform> element and associated subelements of an XML digital signature. Transforms are applied in the order in which they were added. If no transforms are specified, the minimum required transforms are added automatically. For more information about XML digital signatures, see the W3C specification. . This is more rare if you are using Entity Framework (EF) because it requires to have parameterless constructor. However, if the scenario occurs, remember that AutoMapper does not have this constrain. In fact, you can have a private parameterless constructor for Entity Framework (EF) and force the use of a public constructor with parameters when. AutoMapper 一对多; AutoMapper AddTransform; ...

But the thing that we need to keep in mind here is, we created the address property as a complex type. Then we are creating a static method i.e. InitializeAutomapper where we write the mapping code as shown in the below image. Below is the complete code. AutoMapper calls these configuration classes "Profiles." You define your own profile by creating a class that inherits from AutoMapper.Profile. Listing 2, is an example Profile that I could've used in the sample code -- it only includes a few of the CreateMap calls. Configuring AutoMapper using a Profile is simple:. Step by step walkthroughs. Will see step by step how we can integrate Automapper to a project. Step 1. Add the AutoMapper.Extensions.Microsoft.DependencyInjection Package to your solution via NuGet. Step 2. Create two files as Customer.cs and CustomerModel.cs and add class Customer and CustomerModel. public class Customer {. The CreateMap Method. All mapping definitions for AutoMapper are created using the CreateMap method. This is actually and generic method that takes two class types in the form of: AutoMapper.Mapper.CreateMap<SourceClass, DestinationClass> (); It's important to note that this is a one-way mapping.

The Automapper Reverse Mapping is nothing but the two-way mapping which is also called as bidirectional mapping. As of now, the mapping we discussed are one directional means if we have two types let's say Type A and Type B, then we Map Type A with Type B. But using Automapper Reverse mapping it is also possible to Map Type B with Type A. . Value transformers apply an additional transformation to a single type. Before assigning the value, AutoMapper will check to see if the value to be set has any value transformations associated, and will apply them before setting. You can create value transformers at several different levels: var configuration = new MapperConfiguration(cfg. .

This is quite a good practical use case of Automapper in ASP.NET Core Applications. Let’s add a new property Salary and Compensation property to each of our models. Now we need to explicitly tell Automapper that, ‘Every other property names match except one, so I need you to map Salary to Compensation’. Next, we enter the project details and click "Create". From the list of ASP.NET Core web applications, we select "Web Application (Model-View-Controller) and leave all other values as default. We now have the ASP.NET Core MVC application created.

AutoMapper in C# is an open-source library present in GitHub where anybody can contribute. It is crucial for mapping properties between objects. AutoMapper is used whenever there are many data properties for objects, and we need to map them between the object of source class to the object of destination class, Along with the knowledge of data. In the previous tutorial you displayed related data. In this tutorial you'll update related data. For most relationships, this can be done by updating either foreign key fields or navigation properties. For many-to-many relationships, the Entity Framework doesn't expose the join table directly, so you add and remove entities to and from the. AutoMapper is simple a dependency injection that is used to map one object type to another object type. As you know, before Automapper, when we would map the view model object to the domain model object, then we would manually do for each property. This is not only time consuming, but also error-prone. If you observe here, the null property is returning in response. So, the solution to avoid null properties in response is add a piece of code inside ConfigureServices method of Startup.cs file like below. .AddJsonOptions (options => options.SerializerSettings.NullValueHandling = Newtonsoft.Json.NullValueHandling.Ignore);. 1. 2. CreateMap < Source, Destination >() .AddTransform<string>( s => string.IsNullOrEmpty( s) ? null : s); 此构造将转换所有"字符串"类型成员,如果它们为null或为空,则替换为null. 取决于您要执行的操作-如果有一些字符串字段想要保留空字符串而不转换为null,或者您想威胁所有相同. AutoMapper AfterMap | Test your C# code online with .NET Fiddle code editor. . The AutoMapper in C# allows us to add conditions to the properties of the source object that must be met before that property going to be mapped to the property of the destination object. For example, if we want to map a property only if its value is greater than 0, then in such a situation we need to use C# AutoMapper Conditional Mapping. . This is more rare if you are using Entity Framework (EF) because it requires to have parameterless constructor. However, if the scenario occurs, remember that AutoMapper does not have this constrain.

REST : 具象状态传输 (Representational State Transfer,简称REST) ,是Roy Thomas Fielding博士于2000年在他的博士论文 "Architectural Styles and the Design of Network-based Software Architectures" 中提出来的一种万维网软件架构风格。. 目前在三种主流的Web服务实现方案中,因为 REST 模式与复杂的.

To make this demo simple, here we created both the classes with the same property names. But the thing that we need to keep in mind here is, we created the address property as a complex type. Then we are creating a static method i.e. InitializeAutomapper where we write the mapping code as shown in the below image. Below is the complete code. The AddTransform method modifies the <Transform> element and associated subelements of an XML digital signature. Transforms are applied in the order in which they were added. If no transforms are specified, the minimum required transforms are added automatically. For more information about XML digital signatures, see the W3C specification. Eine Alternative zur Verwendung von AutoMapper wäre die Verwendung von Reflektionen. (Beachten Sie, dass der Code im Link eine flache Kopie ist!) In AutoMapper Version 0.2 wurde die Unterstützung für das Befüllen eines vorhandenen Objekts anstelle des AutoMappers, das Zielobjekt selbst erstellt, hinzugefügt. When AutoMapper comes across the same property name on the source and destination classes with different types, it will helpfully automatically attempt to map from one type to the other. This means that you can map entire object hierarchies in a single Map call, which is extremely powerful. How to convert UTC time to local time INTRODUCTION .

最佳答案. 考虑映射器配置文件的值转换构造. CreateMap<Source, Destination> () .AddTransform< string > ( s => string .IsNullOrEmpty (s) ? null : s); 此构造将转换所有"字符串"类型成员,如果它们为 null 或为空,则替换为 null. 关于c# - 使用 AutoMapper 用空值替换空字符串,我们在Stack. Step by step walkthroughs. Will see step by step how we can integrate Automapper to a project. Step 1. Add the AutoMapper.Extensions.Microsoft.DependencyInjection Package to your solution via NuGet. Step 2. Create two files as Customer.cs and CustomerModel.cs and add class Customer and CustomerModel. public class Customer {.
