F＃等同于析构函数 [英] F# Equivalent of Destructor

问题描述

我正在翻译将非托管库包装为F＃的C＃类。我遇到了重写以下析构函数的看似简单的问题。

I am translating a C# class that wraps an unmanaged library to F#. I have run into the seemingly simple problem of rewriting the destructor that follows.

class Wrapper {

    // P/Invoke ellided

    private SomeType x;

    public Wrapper() {
        x = new SomeType();
        Begin();
    }

    public ~Wrapper() {
        End();
    }

我现在拥有的简化F＃代码如下：

The simplified F# code I have at this point is as follows:

type Wrapper() =
  [<Literal>]
  static let wrappedDll = "Library.dll"

  [<DllImport(wrappedDll , EntryPoint = "Begin")>]
  static extern void Begin()

  [<DllImport(wrappedDll , EntryPoint = "End")>]
  static extern void End()

  let x = new SomeType()

  do
    Begin()

如何修改此F＃代码以具有相同的行为？我对F＃析构函数的搜索未在我拥有或在网络上的书中找到任何结果。

How can I modify this F# code to have the same behaviour? My search for F# destructor turned up no results in the books I have or on the web.

谢谢。

推荐答案

是否尝试过查找F＃终结器？

Have you tried looking for F# finalizer?

override x.Finalize() = ...
