本文实例为大家分享了C#使用winform实现进度条效果的具体代码，供大家参考，具体内容如下

1.例子

2.点击查询按钮代码

private void button8_Click(object sender, EventArgs e)
    {
      string orgid = string.Empty;
      string scbz = string.Empty;
      if (comboBox7.SelectedIndex == -1)
      {
        orgid = "";
      }
      else
      {
        orgid = comboBox7.SelectedItem.ToString().Substring(0, 6);
      }
      if (comboBox8.SelectedIndex == -1)
      {
        scbz = "";
      }
      else
      {
        scbz = comboBox8.SelectedItem.ToString().Substring(0, 1);
      }
      Det_SummaryDataContext org = new Det_SummaryDataContext();
      var query = from item in org.Peo_EmployeeInfo
            orderby item.StaID
            where (string.IsNullOrEmpty(orgid) || item.StaID == orgid)
              && (string.IsNullOrEmpty(scbz) || item.SCBZ == scbz)
            select item;
      dataGridView4.DataSource = query.ToList();
      label16.Text = "共" + dataGridView4.RowCount + "条数据";
      progressBar1.Value = 0;//初始化进度条的值
      progressBar1.Minimum = 0;
      progressBar1.Maximum = dataGridView4.RowCount;//设置进度条范围
    }

3.点击手动上传按钮代码

private void button7_Click(object sender, EventArgs e)
    {
      if (dataGridView4.DataSource == null)
      {
        MessageBox.Show("没有需要上传的数据", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
      }
      else
      {
        int sumcout = 0;
        int upcount = 0;
        foreach (DataGridViewRow row in dataGridView4.SelectedRows)
        {
          sumcout += 1;
          progressBar1.Valpythonue++;//动态显示进度条进度
          Application.DoEvents();//处理当前在消息队列中的所有Windows消息

          string orgid = row.Cells["StaID"].Value.ToString();
          string empid = row.Cells["EmpID"].Value.ToString();

          Det_SummaryDataContext det = new Det_SummaryDataContext();
          string cityid = (from sys in det.Base_SystemParameter
                  select sys.CityID).ToList()[0];

          root r = new root();
          head h = new head();
          body b = new body();
          string strXML = string.Empty;
          string restr = string.Empty;
          ServiceReference1.VeptsServiceImplClient vsc = new ServiceReference1.VeptsServiceImplClient();
          int evl = 0;

          var query1 = from ur in det.Peo_TUserRole
                join ri in det.Peo_RoleInfo on ur.RoleID equals ri.RoleID into A
                from urri in A.DefaultIfEmpty()
                select new
                {
                  UADID = ur.UADID,
                  RoleID = ur.RoleID,
                  RoleName = urri.RoleName
                };
          var query2 = from q in query1
                join tu in det.Peo_TUserRightRelation on q.UADID equals tu.UADID into B
                from qtu in B.DefaultIfEmpty()
                select new
                {
                  UADID = q.UADID,
                  RoleID = q.RoleID,
                  RoleName = q.RoleName,
                  EmpID = qtu.EmpID
                };
          var query = from q in query2
                join ei in det.Peo_EmployeeInfo on q.EmpID equals ei.EmpID into C
                from qei in C.DefaultIfEmpty()
                where qei.EmpID == empid
                select new JCZ03
                {
                  idcardno = qei.IDNumber,
                  tsno = cityid + qei.StaID.Substring(4, 2),
                  personname = qei.EmpName,
                  culturegrade = qei.Educational,
                  workdate = qei.DivisionTime,
                  //1站长 2技术负责人 3质量负责人 4外检员 5登录员 6驾控员 7尾气操作员 8其他
                  jobduty = q.RoleID == "130100002" ? "5" : q.RoleID == "130100003" ? "7" : q.RoleID == "130100004" ? "7" : q.RoleID == "130100005" ? "6" : q.RoleID == "130100006" ? "1" : "8",
                  //状态（0：未审；1：在岗；2：离职，3 锁止）
                  state = qei.EmpState == "0" ? "1" : "2"
                };

          List<JCZ03> jcz033 = query.ToList<JCZ03>();
          h.organ = Properties.Settings.Default.JKBH;
          h.jkxlh = Properties.Settings.Default.JKXLH;
          h.jkid = "JCZ03";
          b.vehispara = jcz033[0];
          r.head = h;
          r.body = b;
          strxml = Other.XmlSerialize<root>(r);
          Other.WriteLwLog(strxml);//打印发送日志
          restr = System.Web.HttpUtility.UrlDecode(vsc.write(strxml));
          Other.WriteLwLog(restr,false);//打印接受日志
          if (!restr.Contains(@"<code>php1</code>"))
          {
            evl += 1;
          }
          if (evl == 0)
          {
            var query3 = from item in det.Peo_EmployeeInfo
                  where item.StaID == orgid && item.EmpID == empid
                  select item;
            foreach (var item in query3)
            {
              item.SCBZ = "O";
            }
      编程      det.SubmitChanges();
            upcount += 1;//上传数量 成功上传一条就自增1
          }
          else
          {
            var query3 = from item in det.Peo_EmployeeInfo
                  where item.StaID == orgid && item.EmpID == empid
                  select item;
            foreach (var item in query3)
            {
              item.SCBZ = "E";
            }
            det.SubmitChanges();
          }
        }
        MessageBox.Show(string.Format("选中{0}条数据，成功上传{1}条！", sumcout, upcount), "提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
      }
}

4.思路

首先设置processBar的范围，该范围就是要动态处理数据js集的大小。

然后在foreach循环里设置进度条值自增，即processBar.Value++;

最后加上一句Application.DoEvents(); 用来刷新UI显示进度条进度。
