如何在ASP.NET MVC控制器中获取Identity PasswordOptions

Question

我想读取MVC PasswordOptions中配置的Identity .我的配置如下:Startup.csControllerPasswordOptions

services.AddIdentity<ApplicationUser, IdentityRole>(config => {
        config.Password.RequireDigit = true;
        config.Password.RequiredLength = 8;
        config.Password.RequireNonAlphanumeric = true;
});

然后RequireDigit,我如何读取应用程序中的某个或其他位置的PasswordLength,和RequireNonAlphanumeric属性Controller？

使用ASP.NET Core 1.0.1.

只需将IOptions<IdentityOptions>接口注入任何类或控制器的构造函数,如下所示:

 public class MyController : Controller
 {
     private readonly IOptions<IdentityOptions> _identityOptions;
     public MyContoller(IOptions<IdentityOptions> identityOptions)
     {
         _identityOptions=identityOptions?.Value ?? new IdentityOptions();         
     }

     public MyAction()
     {
         var length=_identityOptions.Value.Password.RequiredLength;
     }
 }
