感谢您的帮助！



很抱歉没有发布确切的错误，但是它用德语发布，所以它不会帮助大多数人，但如果我翻译它就像：未处理的WebException - 在Web提示要求期间出现异常错误。

thanks for help!

Sorry for not posting the exact error but its in german so it wont help most of you, but if i translate it it''s like: Unhandled WebException - Exceptional Error During a Web cleint demand.

推荐答案

webClient.DownloadFile（http://www.spadille.net/ aos075install.msi，@C：\ aos075install.msi）;



确保此路径正确且文件实际存在存在于那条路上。

webClient.DownloadFile("http://www.spadille.net/aos075install.msi", @"C:\aos075install.msi");

Make sure this path is correct and a file actually exists at that path.
