F＃继承接口

Question

我在F＃以下的类继承Microsoft.AspNet.Identity.IIdentityValidator接口：

type MyValidation() = 
    inherit IIdentityValidator<string> with 
     member x.ValidateAsync (value:string) : Task<IdentityResult> = 
     ..... 

我收到此错误：

This 'inherit' declaration specifies the inherited type but no arguments. Consider supplying arguments, e.g. 'inherit BaseType(args)'. 

为什么和如何解决它？

关键字inherit只适用于派生类。您需要使用interface：

type MyValidation() = 
    interface IIdentityValidator<string> with 
     member x.ValidateAsync (value:string) : Task<IdentityResult> = 
      ...
