c# 调用Monitor.Pulse()时抛出对象同步错误

Question

我正在尝试在 GUI 系统中的两个线程之间同步。系统的主要任务是初始化两个同步对象并运行两个线程：private FetcherAPI fetcherAPI { get; set; }private FileReader fileReader { get; set; }private object readerLocker;private object writerLocker;public Form1() {    InitializeComponent();    this.fetcherAPI = new FetcherAPI();    this.fileReader = new FileReader();    readerLocker = new object();    writerLocker = new object();    new Thread(() => {        this.fileReader.run(readerLocker);    });    new Thread(() => {        this.fixerAPI.run(writerLocker, readerLocker);    });}private void button1_Click(object sender, EventArgs e) {    Monitor.Pulse(writerLocker);}读者主题：public void run(object readerLocker) {    while(true) {        Monitor.Wait(readerLocker);        readDataFromFileAndPresent();    }}作者主题：public void run(object writerLocker, object readerLocker) {    while(true) {        Monitor.Wait(writerLocker);        fetchCurrency();        Monitor.Pulse(readerLocker);        Monitor.Wait(readerLocker);       }}当按下按钮时，我收到以下错误：object synchronization method was called from an unsynchronized block of code我究竟做错了什么？

仅当您已经拥有锁时（即您位于语句内，或者您已成功用于获取锁），Wait才Pulse可以调用两者。你还没有做过这两件事，所以：确实，它不会起作用。最简单的修复方法是添加一个.lockMonitor.Enterlock(writerLocker)
