c# - 创建的进度条类上的线程 - 使用 C# 的 Windows 应用程序

Question

我有Class创建进度条。但我的问题是，我不想Application.DoEvents()只显示实际事件。我还观察到，填充记录会消耗大量时间Application.DoEvents()，Threading但我无法理解它是如何工作的，以及如何在我的 created 上实现它Class。谁能帮我这样做。

以下是我的代码。

class LoadProgressBar
    {
    public ProgressBar pBar = null;
    public Label lblProgress = null;
    public Label lblTitle = null;

    public Form createProgressBar(int maxValue)
    {
        //create form
        Form pForm = new Form();
        pForm.Size = new Size(260, 70);
        pForm.FormBorderStyle = FormBorderStyle.None;
        pForm.StartPosition = FormStartPosition.CenterScreen;
        pForm.TopMost = true;
        pForm.ShowInTaskbar = false;

        //create label control
        this.lblTitle = new Label();
        this.lblTitle.Location = new Point(5, 5);
        this.lblTitle.Size = new Size(250, 20);
        this.lblTitle.Text = "Processing";

        //create progress bar control
        this.pBar = new ProgressBar();
        this.pBar.Size = new Size(250, 20);
        this.pBar.Maximum = maxValue;
        this.pBar.Minimum = 0;
        this.pBar.Location = new Point(5, 25);

        //create label control
        this.lblProgress = new Label();
        this.lblProgress.Size = new Size(250, 15);
        this.lblProgress.Location = new Point(5, 50);

        //add controls on form
        pForm.Controls.Add(this.pBar);
        pForm.Controls.Add(this.lblProgress);
        pForm.Controls.Add(this.lblTitle);

        return pForm;
    }

    public void overrideMaxValue(int maxValue)
    {
        this.pBar.Maximum = maxValue;
    }

    public void upldateProgress(int step, string caption)
    {
        if (this.pBar.Value + step <= this.pBar.Maximum)
        {
            this.pBar.Value += step;
        }
        this.lblProgress.Text = caption;
        Application.DoEvents();
    }

}



//Main Sub

static void Main()
{
    //create instance of progressbar class
    LoadProgressBar progBar = new LoadProgressBar();

    //create form for progress bar
    Form loadBar = progBar.createProgressBar(0);

    List<MasterList> empList = new List<MasterList>();

    loadBar.Show(); //show progressbar

    progBar.upldateProgress(0, "Reading File Content..."); //update current progress state

    empList = readFileContent(); //get the data on csv file

    //populate content
    foreach (MasterList empInfo in empList)
    {
        progBar.upldateProgress(1, "Populating : " + empInfo.EmpNo); //update current progress state

        list = lvList.Items.Add(empInfo.EmpNo);
        list.SubItems.Add(empInfo.LastName);
        ...
    }

}
