C# 中的BackgroundWorker 问题

我的组件“BackgroundWorker”有问题

当我单击按钮时，我必须执行 n 次迭代，这需要时间，并且我必须将此操作委托给

我遵循本教程的另一个线程：教程（在french)

这是我的代码：

    private void btnIterate_Click(object sender, EventArgs e)
    {
        bgwIterer.RunWorkerAsync();                
    }

    private void bgwIterer_DoWork(object sender, DoWorkEventArgs e)
    {
        BackgroundWorker worker = sender as BackgroundWorker;
        e.Result = new Iterate(btnIterate, btnReinit, txtInput, lblState, entree, worker, e);
    }

    private void bgwIterer_ProgressChanged(object sender, ProgressChangedEventArgs e)
    {
        this.lblState.Text = e.ProgressPercentage;
    }

bgwIterer 是我的 BackgroundWorker 组件这是我想要委托的方法：

类迭代
{
    // 迭代类的附加构造函数：
    公共迭代（按钮 mybtnIterate，按钮 mybtnReinit，
    文本框 mytxtInput，标签 mylblState，
    int myentree，BackgroundWorker工人，
    DoWorkEventArgs e)
    {
        int 倾角 = 0;
        int var0 = 0, var1;
        mybtnIterate.Enabled = false;
        mytxtInput.Focus();
        做
        {
            变量1=0；
            做
            {
                ++var1；
            }
            while (var1 < myentree);
            ++var0；
            浇注=（var0 / myentree）* 100；
            工人.ReportProgress(pourcent);
        }
        while (var0 < myentre);
        mylblState.Text = "终止！";
        mytxtInput.Enabled = false;
    }

}

就是问题所在：

找不到类型或命名空间名称“BackGroundWorker”（您是否缺少 using 指令或程序集引用？）

有人有想法吗？

原文

I have a problem with a component "BackgroundWorker"

When I click on a button I have to perform n iterations that take time and I have to delegate this operation to another thread

I followed this tutorial: tutorial (in french)

Here is my code:

    private void btnIterate_Click(object sender, EventArgs e)
    {
        bgwIterer.RunWorkerAsync();                
    }

    private void bgwIterer_DoWork(object sender, DoWorkEventArgs e)
    {
        BackgroundWorker worker = sender as BackgroundWorker;
        e.Result = new Iterate(btnIterate, btnReinit, txtInput, lblState, entree, worker, e);
    }

    private void bgwIterer_ProgressChanged(object sender, ProgressChangedEventArgs e)
    {
        this.lblState.Text = e.ProgressPercentage;
    }

bgwIterer is my BackgroundWorker component
and here is the method I would like to delegate:

class Iterate
{
    // Constructeur surchargé de la classe Iterate:
    public Iterate(Button mybtnIterate, Button mybtnReinit,
    TextBox mytxtInput, Label mylblState,
    int myentree, BackgroundWorker worker,
    DoWorkEventArgs e)
    {
        int pourcent = 0;
        int var0 = 0, var1;
        mybtnIterate.Enabled = false;
        mytxtInput.Focus();
        do
        {
            var1 = 0;
            do
            {
                ++var1;
            }
            while (var1 < myentree);
            ++var0;
            pourcent = (var0 / myentree) * 100;
            worker.ReportProgress(pourcent);
        }
        while (var0 < myentree);
        mylblState.Text = "Terminé !";
        mytxtInput.Enabled = false;
    }

}

and this is the problem:

The type or namespace name 'BackGroundWorker' could not be found (are you missing a using directive or an assembly reference?)

Does someone have an idea?
