F#继承接口

Question

我在 F# 中有以下 class 继承 Microsoft.AspNet.Identity.IIdentityValidator 接口：

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

我收到这个错误：

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

为什么以及如何解决？

Answer 1

关键字 inherit 仅用于派生类。您需要使用 interface:

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

F#继承接口
