C# winform壓縮文件夾帶進度條

注意：用了開源的CL.IO.Zip庫

pbYSJD是進度條的控件名

btnImport是按鈕控件名，當壓縮結束之后，使按鈕處於激活狀態，否則無法點擊按鈕。

/// <summary>
        /// 壓縮文件夾並復制到制定目錄

        /// <param name="strPath">待壓縮的文件夾路徑</param>
        /// <param name="strZipPath">需要復制到的目錄路徑（該路徑需要帶壓縮文件名）</param>
        private void ImportZip(string strPath,string strZipPath)
        {
            ZipHandler handler = ZipHandler.GetInstance();
            TaskFactory fastory = new TaskFactory();
            Task[] tasks = new Task[]

                    pbYSJD.Value = Convert.ToInt32(num);
                });
                })
            };
            fastory.ContinueWhenAll(tasks, TasksEnded);

        }
        private void TasksEnded(Task[] tasks)
        {
            MessageBox.Show("壓縮完成", "提示");
            btnImport.Enabled = true;
        }
