ProcessBar窗口类

一、设计器

二、设计器源码

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using System.Threading;

namespace OPCClientDemo
{
    public partial class ProcessFrom : Form
    {
        public ProcessFrom(int _Minimum, int _Maximum)
        {
            InitializeComponent();
            progressBar1.Maximum = _Maximum;
            progressBar1.Value = progressBar1.Minimum = _Minimum;
        }
        public void setPos(int iValue, string sTip = "系统启动中...")
        {
            if (iValue < this.progressBar1.Maximum)
            {
                progressBar1.Value = iValue;
                lbl_status.Text = sTip;
                lbl_percent.Text = (iValue * 100 / progressBar1.Maximum).ToString() + "%";
                Thread.Sleep(1);
            }
            Application.DoEvents();
        }

        private void ProcessFrom_Load(object sender, EventArgs e)
        {
            this.Owner.Enabled = false;

        }

        private void ProcessFrom_FormClosed(object sender, FormClosedEventArgs e)
        {
            this.Owner.Enabled = true;
        }
    }
}

三、应用
1、主程序

int nProcessValue = 0;
ProcessFrom processForm;

1、窗体加载中

processForm = new ProcessFrom(10, 100);
processForm.StartPosition = FormStartPosition.CenterScreen;
InitiaSys();

2、InitiaSys方法

 private void InitiaSys()
        {
            try
            {
                this.Show();
                //this.WindowState = FormWindowState.Maximized;窗体最大化
                this.Hide();
                processForm.Show(this);
                nProcessValue = 10;
                SetPos(nProcessValue, "上位机启动中...");
                nProcessValue = 15;
                SetPos(nProcessValue, "加载配置文件...");
                nProcessValue = 80;
                SetPos(nProcessValue, "上位机加载成功...");
                nProcessValue = 95;
                SetPos(nProcessValue, "启动系统成功...");      

            }
            catch (Exception ex)
            {

            }
            finally
            {
                processForm.Close();
                this.Show();
            }
        }
