WinForm程序进度条：ProcessBar －一个实例应用

设计过程:

ProcessBar窗体:

在窗体中央放一个progressBar1控件与label1,label2

声明访问类型改为public:

(即)

public System.Windows.Forms.ProgressBar progressBar1;

public System.Windows.Forms.Label label1;

public System.Windows.Forms.Label label2;

 

Form1窗体:

放置按钮button1

        private void button1_Click(object sender, EventArgs e)

        {

            ProcessBar pj = new ProcessBar();

            pj.Show();

            //开始处理工作

            for (int i = 0; i < 200000; i++)

            {

                if (i % 2000 == 0)

                {

                    if (pj.progressBar1.Value == 100)

                        pj.progressBar1.Value = 0;

                    pj.progressBar1.Value++;

                    pj.label1.Text = "已完成：" + string.Format("{0:p}", (double)pj.progressBar1.Value / 100);

                    pj.label2.Text = "正在处理:第" + i + "程序";

                    Application.DoEvents();

                }

            }

            pj.Close();

        }

 

呵呵，简单吧   

应用程序好少做呢!
