F#一种扩展方法引用另一种扩展方法 [] 静态成员ToOrganizationRequest OrganizationRequest>（实体：实体）= let request=Activator.CreateInstance（typeof（））

第二个extensionmethod无法引用第一个，因此

|>Seq.map（fun x->x.ToOrganizationRequest如果您不需要在C#中显示扩展方法，您可以（也可能应该）像这样扩展

实体

类型：

[<Extension>]
static member ToOrganizationRequest<'T when 'T :> OrganizationRequest> (entity: Entity) =
    let request = Activator.CreateInstance(typeof<'T>) :?> OrganizationRequest
    request.Parameters.Item "Target" <- entity
    request

[<Extension>]
static member ToOrganizationRequest<'T when 'T :> OrganizationRequest> (entities: seq<Entity>) = 
    entities
    |> Seq.map (fun x -> x.ToOrganizationRequest<'T>())

使用
成员this.ToOrganizationRequest OrganizationRequest>（）=
let request=Activator.CreateInstance（typeof（））

如果在C#中确实需要它们，则必须在定义扩展方法的类型中静态调用其他扩展方法

[<Extension>]
type Ext =
    [<Extension>]
    static member ToOrganizationRequest<'T when 'T :> OrganizationRequest> (entities: seq<Entity>) = 
        entities
        |> Seq.map (fun x -> x.ToOrganizationRequest<'T>())

[]
类型Ext=
[]
静态成员ToOrganizationRequest OrganizationRequest>（实体：实体）=
让请求=Activator.CreateInstance（typeofstatic成员可以通过
TypeName.StaticMember
，所以试着用它来代替
this.StaticMember
你是什么意思？我应该可以做一些类似实体的事情。ToOrganizationRequest我从C#调用代码。工作得很好，非常感谢！实际上@TheInnerLight F#风格的扩展方法不会对于第二种方法来说，这是不允许的，因为
这个
应该是
seq
；你需要用…
写
键入seq，这是不允许的。@Tarmil谢谢，我认为这个故事的寓意是不要匆忙写答案：）
