简介

在winform项目中，我们常常需要弹出一个窗体显示处理的进度，All in one code中的progress不能满足我们的需求，所以就有了ProgressForm.

ProgressForm对外开放了一个DoExecute抽象方法，以便使用者override .

public abstract class Action
     

{

protected abstract TResult DoExecute(ProgressForm
     
       progressForm);
     

public TResult Execute(Form ownerForm, string title, string initialMessage, bool customProgress = false)

{

return ProgressForm
     
      .ExecuteAction(ownerForm, new ExecuteActionDelegate
      
       (DoExecute), title, initialMessage, customProgress);
      
     

}

}

ProgressForm继承自IProgressDelegate，以便通知界面更改进度条百分比和Message .

public partial class ProgressForm
     
       : Form, IProgressDelegate
     

接口定义：

/// 

/// Public interface used to notify progress changes

/// 

public interface IProgressDelegate

{

void NotifyProgressMessageChanged(string message);

void NotifyProgressChanged(int percentage);

}

 

使用方式

private void testProgress_Click(object sender, EventArgs e)

{

TestClass t = new TestClass();

t.Execute(this.ParentForm, "窗体名称", "Message", true);

}

 

重写DoExecute

public class TestClass : DeploymentTools.UserInterface.Actions.Action
     

{

protected override string  DoExecute(ProgressForm
     
       progressForm)
     

{

progressForm.NotifyProgressChanged(10);

progressForm.NotifyProgressMessageChanged("已经完成10%");

Thread.Sleep(2000);

progressForm.NotifyProgressChanged(20);

progressForm.NotifyProgressMessageChanged("已经完成20%");

Thread.Sleep(2000);

progressForm.NotifyProgressChanged(30);

progressForm.NotifyProgressMessageChanged("已经完成30%");

Thread.Sleep(2000);

progressForm.NotifyProgressChanged(40);

progressForm.NotifyProgressMessageChanged("已经完成40%");

Thread.Sleep(2000);

progressForm.NotifyProgressChanged(50);

progressForm.NotifyProgressMessageChanged("已经完成50%");

Thread.Sleep(2000);

progressForm.NotifyProgressChanged(60);

progressForm.NotifyProgressMessageChanged("已经完成60%");

Thread.Sleep(2000);

progressForm.NotifyProgressChanged(70);

progressForm.NotifyProgressMessageChanged("已经完成70%");

Thread.Sleep(2000);

progressForm.NotifyProgressChanged(80);

progressForm.NotifyProgressMessageChanged("已经完成80%");

Thread.Sleep(2000);

progressForm.NotifyProgressChanged(90);

progressForm.NotifyProgressMessageChanged("已经完成90%");

Thread.Sleep(2000);

progressForm.NotifyProgressChanged(100);

progressForm.NotifyProgressMessageChanged("全部处理完成！");

Thread.Sleep(2000);

return string.Empty;

}

}

这里返回值是string,我们可以返回任何类型TResult，以便两个窗体之间的交互。
