问题描述

和显示如何映射

从第一个链接:

    public void ConfigureServices(IServiceCollection services)
    {
        services.Configure<AppSettings>(Configuration.GetConfigurationSection("AppSettings"));
        services.AddMvc();
    }

但是,我没有得到 Configure )方法服务。所以我缺少一个包,或者API已经改变。这是什么?

However, I'm not getting the Configure() method on services. So either I'm missing a package, or the API has changed. Which is it?

我使用的是RC1。我相信这篇文章是基于beta 4.

推荐答案

这个例子应该给你你需要的。我有这个类:

This example should give you what you need. I have this class:

public class UIOptions
{
    public UIOptions()
    { }

    public int DefaultPageSize_SiteList { get; set; } = 10;
    public int DefaultPageSize_CountryList { get; set; } = 10;
    public int DefaultPageSize_StateList { get; set; } = 10;
    public int DefaultPageSize_RoleList { get; set; } = 10;
    public int DefaultPageSize_RoleMemberList { get; set; } = 10;
    public int DefaultPageSize_UserList { get; set; } = 10;
    public int DefaultPageSize_LogView { get; set; } = 10;

}

如果我想覆盖任何默认值将它添加到我的appsettings.json中:

If I want to override any of the default values I can add this in my appsettings.json:

"UIOptions": {
"DefaultPageSize_SiteList" : "5"
}

但是如果我不改变任何东西, appsettings.json文件。

But if I'm not changing anything it doesn't matter if this exists in the appsettings.json file.

在启动时,我有:

services.Configure<UIOptions>(Configuration.GetSection("UIOptions"));

在需要注入选项的控制器中,我对

In a controller where I need the options injected I have a constructor dependency on

IOptions<UIOptions>

注意,我从IOptions的.Value属性获取UIOptions实例

Note that I get my UIOptions instance from the .Value property of the IOptions

using Microsoft.Extensions.OptionsModel;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.DependencyInjection.Extensions;

public class CoreDataController : Controller
{
    public CoreDataController(
        IOptions<UIOptions> uiOptionsAccessor
        )
    {

        uiOptions = uiOptionsAccessor.Value;
    }

    private UIOptions uiOptions;

}
