C# 由于button.performClick（）的原因，跨线程操作无效

您好，我正在研究一个禁忌搜索算法，我需要访问许多函数以使其可读性和易用性。我使用了按钮和button.performClick（）

有人能告诉我我做错了什么，以及我如何解决这个问题吗？ 多谢各位

    struct DataParameter
    {
        public int Process;
        public int Delay;
    }

    private void backgroundWorker_ProgressChanged(object sender, ProgressChangedEventArgs e)
    {
        progressBar1.Value = e.ProgressPercentage;
        lblBackGroundWorker.Text = string.Format("Processing...{0}%", e.ProgressPercentage);
        progressBar1.Update();

将此代码添加到while循环的末尾（循环内）

DateTime timeout=DateTime.Now.add毫秒（50）；
while（DateTime.Now

它应该会起作用

祝你好运

请查看的指南。特别是-正在发生的事情与你期望发生的事情。你收到错误信息了吗？如果是，是什么？什么是

按钮。performClick

-它不会出现在您的代码中？此外，这很可能是的重复-这是一个非常常见的问题…不要尝试在

DoWork

中显示消息框。此方法在与UI线程不同的线程上执行。传递信息并处理

RunWorkerCompleted

事件中的错误，该错误将在UI线程上执行。当您在单击处理程序中测试它只应在backgroundworker未运行时执行某项操作时，为什么要从DoWork调用cmd\u Start\u Scheduling.PerformClick（）？看起来很荒谬。因为那个按钮连接到一个函数，为什么我得到了-1？我只是在帮助那个家伙，这可能不是最好的答案，但它works@TimJones如果你知道这是一个糟糕的答案，那么你为什么要把它放在首位？如果你知道一个答案是错误的，而你却得到了反对票，那你为什么会感到惊讶呢？你刚刚带领OP走上了一条可能会给他带来更多问题的道路，并且可能很难调试这些问题！

DateTime timeout = DateTime.Now.AddMilliseconds(50);
while (DateTime.Now < timeout) Application.doEvents;
