实现winform进度条？

[zkvistor]

WinForm窗体中发短信要实现一个进度条，找了一个是用循环做的，进度条的速度太快了，效果不好，怎么实现效果会好一些？用backgroundWorker，具体怎么实现，能否附上一些代码？

后台类：
public class PublishHelper
{
private static PublishHelper helper;
public static PublishHelper Instance
{
get
{
if ( helper == null )
{
helper = new PublishHelper();
}
return helper;
}
}


/// <summary>
/// 获取文件列表
/// </summary>
/// <param name="BaseDir">APP地址</param>
/// <returns>List列表</returns>
public AssemblyInfoFileList GetFileList( string BaseDir )
{
AssemblyInfoFileList afl = GetClientUpdateList( BaseDir );
return afl;
}

/// <summary>
/// 私有方法，递归数据给上面客户端列表
/// </summary>
/// <param name="BaseDir">APP地址</param>
/// <returns>List列表</returns>
private AssemblyInfoFileList GetClientUpdateList( string BaseDir )
{
if ( String.IsNullOrEmpty( BaseDir ) )
{
BaseDir = Path.Combine( AppDomain.CurrentDomain.BaseDirectory, "UpdateClient" );
}

return AssemblyHelper.GetAssemblyList( BaseDir );
}


/// <summary>
/// 进行文件COPY的方法[线程回调]
/// </summary>
/// <param name="filelist">文件列表</param>
/// <param name="UserPath">用户选择的路径</param>
/// <param name="bar">进度条</param>
/// <param name="lab">标签条</param>
public void ShareSession( AssemblyInfoFileList filelist, string UserPath, string publishPath,ProgressBar bar, Label lab )
{
int cm = 100 / filelist.Count;

if ( File.Exists( AssemblyHelper.AssemblyListFileName ) ) File.Delete( AssemblyHelper.AssemblyListFileName );
//string AppPath =Path.Combine( System.AppDomain.CurrentDomain.BaseDirectory, "UpdateClient" );
string AppPath = Path.Combine(publishPath, "UpdateClient");
if (!Directory.Exists(AppPath))
{
Directory.CreateDirectory(AppPath);
}
foreach ( AssemblyInfoFile temp in filelist )
{
if ( bar.Value < 100 ) { bar.Value += cm; }
lab.Text = "正在下载:" + temp.RelativePath;
string remoteFileName = temp.RelativePath;
if ( remoteFileName.IndexOf( "\\" ) > 0 )
{
string file = remoteFileName.Substring( remoteFileName.LastIndexOf( "\\" ) + 1, remoteFileName.Length - remoteFileName.LastIndexOf( "\\" ) - 1 );
string[] spli = { "\\" + file };
string path = remoteFileName.Split( spli, StringSplitOptions.RemoveEmptyEntries )[ 0 ];
if ( !Directory.Exists( Path.Combine( AppPath, path ) ) )
{
Directory.CreateDirectory( Path.Combine( AppPath, path ) );
}
}
File.Copy( Path.Combine( UserPath, remoteFileName ), Path.Combine( AppPath, remoteFileName ), true );
}
bar.Value = 100;
lab.Text = "文件更新成功完成";
}

}


界面调用：

string strAppCode = this.tslAppCode.Text;

if ( this.UpdatedFile.Count == 0 || String.IsNullOrEmpty( strAppCode ) || strAppCode == "应用系统" )
{
return;
}

try
{
if ( MessageBox.Show( String.Format( "您确定要更新文件夹{0}下的{1}个文件到{2}系统么? ", this.LocalRootDirectory.FullName,
this.UpdatedFile.Count, strAppCode ), "提示", MessageBoxButtons.YesNo, MessageBoxIcon.Question )
== DialogResult.No )
return;

tsbUpdate.Enabled = false;
ProgressBarStatus.Visible = true;
ProgressBarStatus.Maximum = UpdatedFile.Count;
ProgressBarStatus.Value = 0;

helper.UploadWholeDir = false;
helper.UploadFile( this.UpdatedFile, strAppCode );

MessageBox.Show( "更新服务完成", "提示", MessageBoxButtons.OK, MessageBoxIcon.Information );
}
catch ( Exception ex )
{
MessageBox.Show( "更新失败" + ex.Message, "提示", MessageBoxButtons.OK, MessageBoxIcon.Error );
LogManager.WriteError( ex );
}
finally
{
ProgressBarStatus.Visible = false;
this.labelInfo.Text = "就绪";
tsbUpdate.Enabled = true;
}

这里。都是多线程的，看看吧

怎么实现效果会好一些?我觉得贴个图片效果就很好了 呵呵

多线程。

效果不好是因为用循环做，进度条加载的速度太快了，和图片没关系

那就用多线程吧，这个比较好

winform用BackgroudWoker异步显示进度条

[优途科技]

例子参考：http://blog.csdn.net/gisfarmer/archive/2009/01/09/3742019.aspx

我也在找这个问题难道大家爱没有很好的解答吗？？？

[快乐小子飞]

这个效果是从100线程减到0，进度条的显示。

public Thread th1;

delegate void SetValues(int i);
delegate void ShowProBar(int i);

private void button1_Click(object sender, EventArgs e)
{
  th1 = new Thread(new ThreadStart(test1));
  th1.Start();
}
private void test1()
{
  int i = 100;
  while (i > -1)
  {
  setvalue1(i);
  ShowProgress1(i);
  i--;
  Thread.Sleep(1000);
  }
}
private void setvalue1(int i)
{
  if (this.InvokeRequired)
  {
  this.Invoke(new SetValues(setvalue1), new object[] {i});
  }
  else
  {
  自己的操作
  }
}
private void ShowProgress1(int i)
  {
  if (this.progressBar1.InvokeRequired)
  {
  this.Invoke(new ShowProBar(ShowProgress1), new object[] { i });
  }
  else
  {
  progressBar1.Value = 100-i;
  progressBar1.Visible=true;
  }
  }

帮顶，呵呵...

额，大家可能想复杂了哦！！

lz在创体力拖一个Lable，一个button，一个progressBar1

具体code如下：去不铁给你，直接用

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

namespace WinTestUrl
{
    public delegate void SetPos(int ipos);
    public partial class Form2 : Form
    {
        public Form2()
        {
            InitializeComponent();
        }

        public void SetTextMessage(int ipos)
        {
            if (this.InvokeRequired)
            {
                SetPos setpos = new SetPos(SetTextMessage);
                this.Invoke(setpos, new object[] { ipos });
            }
            else
            {
                this.label1.Text = ipos.ToString() + "/10";
                this.progressBar1.Value = Convert.ToInt32(ipos);
            }
        }

        public void button2_Click(object sender, EventArgs e)
        {
            Thread fThread = new Thread(new ThreadStart(SleepT));//开辟一个新的线程 
            fThread.Start();
        }

        public void SleepT()
        {
            for (int i = 1; i <= 100; i++)
            {
                System.Threading.Thread.Sleep(100);//没什么意思，单纯的执行延时 
                SetTextMessage(10 * i / 100);
            }
        }

       
    }
}
