如何制作进度条表格？

问题描述

我的代码如下：



我创建一个进度条形式

my code as follow:

I create a progressbarform

public partial class fmDialog : Form
{
    public int Value
    {
        get
        {
            return progressBar1.Value;
        }
        set
        {
            if (value > progressBar1.Maximum)
            {
                progressBar1.Value = progressBar1.Maximum;
            }
            else
            {
                progressBar1.Value = value;
            }

        }
    }
    public string NoteText
    {
        get
        {
            return label1.Text;
        }
        set
        {
            label1.Text = value;
        }
    }
    public bool IsMaxValue
    {
        get
        {
            return progressBar1.Value == progressBar1.Maximum;
        }
    }
    public fmDialog()
    {
        InitializeComponent();
    }
}

来电：

Call it：

fmDialog fm = new fmDialog();
fm.Show(this);
while (!fm.IsMaxValue)
{
    fm.Value += 10;
}
fm.close();

我的问题是：为什么我看不到进度条形码？我做错了什么？我想手动设置进度条的值。我该怎么办？

My question is: Why do not I see my progressbarform?Where I doing wrong?I want to manually set the value of the progressbar.What should I do?

推荐答案

    BackgroundWorker work = new BackgroundWorker();
    work.WorkerReportsProgress = true;
    work.ProgressChanged += new ProgressChangedEventHandler(work_ProgressChanged);
    work.DoWork += new DoWorkEventHandler(work_DoWork);
    work.RunWorkerAsync();
    }

void work_DoWork(object sender, DoWorkEventArgs e)
    {
    BackgroundWorker work = sender as BackgroundWorker;
    if (sender != null)
        {
        for (int i = 0; i < 100; i += 10)
            {
            work.ReportProgress(i);
            Sleep(500);
            }

        }
    }

void work_ProgressChanged(object sender, ProgressChangedEventArgs e)
    {
    progressBar1.Value = e.ProgressPercentage;
    }
