Use System.Net.WebClient.DownloadFileand you are doing bulk downloads then do use WebClient.DownloadProgressChangedEvent. Sometimes we do bulk download but user get the impression that system stuck or fail somewhere and start hitting refresh. Avoid that!
使用System.Net.WebClient.DownloadFile并且您正在进行批量下载，然后使用WebClient.DownloadProgressChangedEvent。有时我们进行批量下载，但用户会觉得系统卡住或在某处失败并开始点击refresh。避免这种情况！
