推荐答案

关闭时，您无需对当前正在运行的进程执行任何特殊操作即可从文件的一部分开始继续下载相同的文件之前已下载.使用HTTP下载时，您可以跳过其中的一部分，然后开始下载下一个块，将其附加到具有已下载数据的文件中.

如果查看我为CodeProject提供的应用程序HttpDownloader(包含完整的源代码)，则可以找到如何使用此简单技术的信息，请参阅

You don''t need to do anything special to a currently running process at shutdown to continue downloading of the same file starting from the part of the file which was downloaded before. With HTTP downloads, you can skip part of it and start to download next block appending it to the file with already downloaded data.

You can find out how to use this simple technique if you look at my application HttpDownloader I provided for CodeProject with complete source code, please see how to download a file from internet[^]. (This is C#. Too bad you did not indicate your language.)
