Question

我有一个CopyFile和目录项目。但是当我开始复制Gui时，它会冻结。文件复制我无能为力。所以我在BackgroundWorker Component找到了我的解决方案。但我也有这个组件的问题。

有3个单选按钮和命令按钮。当我单击命令按钮时，它会检查是否已选中radiobutton1，或者是否选中了radiobutton2，或者是否选中了radiobutton3。如果检查radiobutton1，做了很多事情，或者如果radiobutton2检查了，那么做另外的事情等等。有3个背光工作者用于3个无线电按钮。当我检查radiobutton1时，backgroundworker1 dowork事件正在运行。当我检查radiobutton2时，backgroundworker2 dowork事件正在运行。等...

我的问题是当我选中radiobutton1并单击“命令”按钮时。从backgroundworker1开始做工作事件，但它也会继续控制是否选中radiobutton2。它没有停止，所以我得到错误。我的代码如下：

private void button1_Click(object sender, EventArgs e)
{
    if (radioButton1.Checked)
    {
        backgroundWorker1.RunWorkerAsync();
    }

    if (radioButton2.Checked)
    {
        StreamReader sr = new StreamReader(Application.StartupPath + @"\hakimler.txt");

        while ((satir = sr.ReadLine()) != null)
        {
            try
            {
                bool copy = CopyDirectory(DosyaYolu.kaynak, @"\\" + satir + @"" + DosyaYolu.hedef, true);
                if (copy)
                {
                    kopya += 1;
                }
                else
                {
                    sw.WriteLine(satir);
                }
            }
            catch (Exception)
            {

            }
        }

        sw.Close();
        MessageBox.Show("İşlem tamamlandı", "İşlem Sonu", MessageBoxButtons.OK, MessageBoxIcon.Information);
        lblkopya.Text = "Başarıyla tamamlanan iş sayısı : " + kopya.ToString();
        return;
    }

    if (chkPersonel.Checked == true)
    {
        StreamReader sr = new StreamReader(Application.StartupPath + @"\personel.txt");

        while ((satir = sr.ReadLine()) != null)
        {
            try
            {
                bool copy = CopyDirectory(DosyaYolu.kaynak, @"\\ab04500-" + satir + @"" + DosyaYolu.hedef, true);
                //bool copy = CopyDirectory(Application.StartupPath + @"\TELEFON REHBERİ", @"\\" + satir + @"\c$\Documents and Settings\All Users\Start Menu", true);
                if (copy)
                {
                    kopya += 1;
                }
                else
                {
                    sw.WriteLine(satir);
                }
            }
            catch (Exception)
            {

            }
        }

        sw.Close();

        MessageBox.Show("İşlem tamamlandı", "İşlem Sonu", MessageBoxButtons.OK, MessageBoxIcon.Information);
        lblkopya.Text = "Başarıyla tamamlanan iş sayısı : " + kopya.ToString();
        return;
    }
    else
    {
        if (txtBilgisayar.Text == "" && txtDongu.Text == "")
        {
            MessageBox.Show("Boşlukları dolduralım bi zahmet :@", "Bilgisayar Kodlarını girelim lütfen!", MessageBoxButtons.OK, MessageBoxIcon.Warning);
            return;
        }

        bilgisayar = Convert.ToInt32(txtBilgisayar.Text);
        dongu = Convert.ToInt32(txtDongu.Text);

        for (int i = bilgisayar; i <= dongu; i++)
        {
            try
            {
                bool copy = CopyDirectory(DosyaYolu.kaynak, @"\\ab04500-" + bilgisayar + @"" + DosyaYolu.hedef, true);
                if (copy)
                {
                    kopya += 1;
                }
                else
                {
                sw.WriteLine(satir);
                }
            }
            catch (Exception)
            {

            }

            if (i == dongu)
            {
                sw.Close();
                MessageBox.Show("İşlem tamamlandı", "İşlem Sonu", MessageBoxButtons.OK, MessageBoxIcon.Information);
                lblkopya.Text = "Başarıyla tamamlanan iş sayısı : " + kopya.ToString();
            }

            bilgisayar += 1;
        }

}


private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
    sw = new StreamWriter(DateTime.Today.ToShortDateString().ToString() + "_ulasmayanlar.txt", true);
    StreamReader sr = new StreamReader(Application.StartupPath + @"\savcilar.txt");

    while ((satir = sr.ReadLine()) != null)
    {
        try
        {
            bool copy = CopyDirectory(DosyaYolu.kaynak, @"\\" + satir + @"" + DosyaYolu.hedef, true);
            //bool copy = CopyDirectory(Application.StartupPath + @"\TELEFON REHBERİ", @"\\" + satir + @"\c$\Documents and Settings\All Users\Start Menu", true);
            if (copy)
            {
                kopya += 1;
            }
            else
            {
                sw.WriteLine(satir);
            }
        }

    }
}

private void backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
    sw.Close();

    MessageBox.Show("İşlem tamamlandı", "İşlem Sonu", MessageBoxButtons.OK, MessageBoxIcon.Information);
    lblkopya.Text = "Başarıyla tamamlanan iş sayısı : " + kopya.ToString();
}

如果radiobutton1的检查是否正确，如果检查是真的，它的开始bgworkers是否正常工作，如果radiobutton2检查是否继续，如果radiobutton3检查或者不检查，当它看到radiobutton1检查为真时，它不会停止。

是的，我想停止控制另一个radiobutton的chechked true或not。如果 radiobutton1的chechked是真的只做背景工作者的事件并停止。

我不太确定您的问题究竟是什么，但在您的代码中radioButton1是然后检查后台工作人员会做的事情，否则它不会。这不是你想要的吗？

我没有看到你提到的其他单选按钮的代码。

啊，所以你想在检查antoher单选按钮时停止后台工作人员？在dowork()方法中，您必须检查是否bg.CancellationPending == true并退出方法。

初始化BG工作人员后，您还必须将WorkerSupportsCancellation设置为true。

如何在C＃中解决涉及BackgroundWorkers的这个问题？
