#asp.net core mvc 的视图注入

View injection is the most useful feature introduced in ASP.NET Core.

1.添加一个FruitsService

public class FruitServices
{
    public List<string> GetFruits()
    {
        return new List<string>() { "Mango", "Apple", "Apricot", "Banana", "Grapes" };
    }
}  

2.Inject in View

基本语法：

@inject <service> <name>

@inject 为DI的指令

待注入服务的名称

服务的名字，代表一个服务的实例。

---FruitsInjection.cshtml---

@inject WebAppWithIndividualUserAccounts.Services.FruitServices fruitService

<h3>Fruit List</h3>

<ul>

 @foreach (var name in fruitService.GetFruits())

 {

     <li>@name</li>

 }

</ul>

3.配置IOC

---Startup.cs---中

public void ConfigureServices(IServiceCollection services)

{

// Add framework services.

 services.AddMvc();

 services.AddTransient<FruitServices>();

}
