封装一个进度条

1.首先定义一个处理数据需要产生进度的接口和抽象类

 1 namespace Progress.Core  2 {  3     public interface IProgress  4  {  5         IProgressView m_FrmProgress { get; set; }  6         PosscessCompleted mPosscessCompleted { get; set; }  7         Thread mThread { get; }  8         bool IsStop { get; set; }  9         void Start(); 10  } 11     public delegate void PosscessCompleted(); 12     public class AbstractProgress : IProgress 13  { 14         private Thread m_Thread; 15         public Thread mThread 16  { 17             get

18  { 19                 return m_Thread; 20  } 21  } 22         public IProgressView m_FrmProgress { get; set; } 23         public bool IsStop { get; set; } 24 

25 

26         public PosscessCompleted mPosscessCompleted { get; set; } 27 

28         public AbstractProgress() 29  { 30             m_Thread = new Thread(new ThreadStart(WorkFunc)); 31  } 32         bool isStart = false; 33         public void Start() 34  { 35             if (mThread != null && isStart == false) 36  { 37  mThread.Start(); 38                 isStart = true; 39  } 40  } 41         private void WorkFunc() 42  { 43             if (IsStop) 44  { 45                 return; 46  } 47  ProcessData(); 48             //处理完成

49             if (mPosscessCompleted != null) 50  { 51  mPosscessCompleted(); 52  } 53  } 54         public virtual void ProcessData() 55  { 56             // mFrmProgress.IsFalse = true;

57  } 58  } 59 

60 }

IProgress

看一个子类实现：

 1 class NumCul : AbstractProgress  2  {  3         public override void ProcessData()  4  {  5             int i = 0;  6             while (true)  7  {  8                 if (IsStop)  9  { 10                     break; 11  } 12                 i++; 13  m_FrmProgress.SetTitle(i.ToString()); 14                 m_FrmProgress.SetProcessBar(i / 100); 15                 if (i > 10000) 16  { 17                     break; 18  } 19  } 20  } 21     }

NumCul

2.进度条窗体的抽象接口：

1  public interface IProgressView 2  { 3         void SetTitle(string title); 4 

5         void SetProcessBar(int percent); 6     }

IProgressView

一个进度条窗体实现：

 1  public partial class FrmProgress : Form, IProgressView  2  {  3         private IProgress mProgress = null;  4         //处理进度条

 5         public delegate void ProgressBarState(int per);  6         public ProgressBarState mProgressPorBar;  7         //处理文字说明

 8         public delegate void TitleState(string title);  9         public TitleState mProgressTitle; 10 

11         //处理按钮状态

12         public delegate void ButtonState(); 13         public ButtonState mButtonState; 14 

15         public FrmProgress(IProgress progress) 16  { 17  InitializeComponent(); 18             mProgress = progress; 19             mProgress.m_FrmProgress = this; 20  } 21 

22         private void FrmProgress_Load(object sender, EventArgs e) 23  { 24             mProgressPorBar += new ProgressBarState(SetProgressBarState); 25             mProgressTitle += new TitleState(SetTitleState); 26             mButtonState += new ButtonState(SetButtonState); 27             mProgress.mPosscessCompleted += new PosscessCompleted(IsCompeted); 28  mProgress.Start(); 29  } 30         public bool IsFalse = true; 31         //给处理线程调用的

32         public void SetTitle(string title) 33  { 34  label1.Invoke(mProgressTitle, title); 35 

36  } 37         //给处理线程调用的

38         public void SetProcessBar(int percent) 39  { 40  progressBar1.Invoke(mProgressPorBar, percent); 41  } 42         public void IsCompeted() 43  { 44             this.button1.Invoke(mButtonState); 45  } 46 

47         void SetTitleState(string title) 48  { 49             label1.Text = title; 50  } 51         void SetProgressBarState(int percent) 52  { 53             progressBar1.Value = percent; 54  } 55         void SetButtonState() 56  { 57             Thread.Sleep(100); 58             button1.Text = "关闭"; 59  } 60 

61         private void button1_Click(object sender, EventArgs e) 62  { 63             if (mProgress != null) 64  { 65                 mProgress.IsStop = true; 66  } 67             this.Close(); 68  } 69 

70         private void FrmProgress_FormClosing(object sender, FormClosingEventArgs e) 71  { 72             if (mProgress != null) 73  { 74                 mProgress.IsStop = true; 75  } 76  } 77       

78     }

进度条窗体

3.调用：

1  private void button2_Click(object sender, EventArgs e) 2  { 3             IProgress pros = new NumCul(); 4             Core.FrmProgress frm = new Core.FrmProgress(pros); 5  frm.ShowDialog(); 6         }
