在winform項(xiàng)目中，我們常常需要彈出一個(gè)窗體顯示處理的進(jìn)度，All in one code中的progress不能滿足我們的需求，所以就有了ProgressForm.

ProgressForm對(duì)外開放了一個(gè)DoExecute抽象方法，以便使用者override .

    public abstract class Action<TResult>

        protected abstract TResult DoExecute(ProgressForm<TResult> progressForm);

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

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

ProgressForm繼承自IProgressDelegate，以便通知界面更改進(jìn)度條百分比和Message .

public partial class ProgressForm<TResult> : Form, IProgressDelegate

接口定義：

    /// <summary>

    /// Public interface used to notify progress changes

    /// </summary>

    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, "窗體名稱", "Message", true);

重寫DoExecute

    public class TestClass : DeploymentTools.UserInterface.Actions.Action<string>

        protected override string  DoExecute(ProgressForm<string> progressForm)

            progressForm.NotifyProgressChanged(10);

            progressForm.NotifyProgressMessageChanged("已經(jīng)完成10%");

            Thread.Sleep(2000);

            progressForm.NotifyProgressChanged(20);

            progressForm.NotifyProgressMessageChanged("已經(jīng)完成20%");

            Thread.Sleep(2000);

            progressForm.NotifyProgressChanged(30);

            progressForm.NotifyProgressMessageChanged("已經(jīng)完成30%");

            Thread.Sleep(2000);

            progressForm.NotifyProgressChanged(40);

            progressForm.NotifyProgressMessageChanged("已經(jīng)完成40%");

            Thread.Sleep(2000);

            progressForm.NotifyProgressChanged(50);

            progressForm.NotifyProgressMessageChanged("已經(jīng)完成50%");

            Thread.Sleep(2000);

            progressForm.NotifyProgressChanged(60);

            progressForm.NotifyProgressMessageChanged("已經(jīng)完成60%");

            Thread.Sleep(2000);

            progressForm.NotifyProgressChanged(70);

            progressForm.NotifyProgressMessageChanged("已經(jīng)完成70%");

            Thread.Sleep(2000);

            progressForm.NotifyProgressChanged(80);

            progressForm.NotifyProgressMessageChanged("已經(jīng)完成80%");

            Thread.Sleep(2000);

            progressForm.NotifyProgressChanged(90);

            progressForm.NotifyProgressMessageChanged("已經(jīng)完成90%");

            Thread.Sleep(2000);

            progressForm.NotifyProgressChanged(100);

            progressForm.NotifyProgressMessageChanged("全部處理完成！");

            Thread.Sleep(2000);

            return string.Empty;

這里返回值是string,我們可以返回任何類型TResult，以便兩個(gè)窗體之間的交互。
