F＃等同于析构函数

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。

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：

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＃代码以使其具有相同的行为？我对F＃析构函数的搜索未在我所拥有的书或网络上的书中找到任何结果。 谢谢。     

解决方法

您是否尝试过寻找F＃终结器？

override x.Finalize() = ...

    ,

namespace FSharp.Library  

type MyClass() as self = 

    let mutable disposed = false;

    // TODO define your variables including disposable objects

    do // TODO perform initialization code
        ()

    // internal method to cleanup resources
    let cleanup(disposing:bool) = 
        if not disposed then
            disposed <- true

            if disposing then
                // TODO dispose of managed resources
                ()

            // TODO cleanup unmanaged resources
            ()

    // implementation of IDisposable
    interface IDisposable with
        member self.Dispose() =
            cleanup(true)
            GC.SuppressFinalize(self)

    // override of finalizer
    override self.Finalize() = 
        cleanup(false)
