generics - F#独特的重载方法

Question

如何以这种类型调用 send(a:'T []) ？

type Test() =
  member o.send(value:'T) = 4
  member o.send(values:'T []) = 5

let test = Test()
let b = test.send [|4|]

当我这样做时，我得到

A unique overload for method 'Send' could not be determined based on type information 
prior to this program point. The available overloads are shown below...

重点是 MPI.NET 已经有了这个名为 Send 的方法，但我无法将数组发送到其中。

谢谢，

Answer 1

type Test() =
  member o.send(a:'T) = 4
  member o.send(a:'T []) = 5

let test = Test()
let b = test.send<int>([|4|] : _[]) // 5
