推荐答案

您不能.即使默认情况下，Upload控件也不会让您知道用户的环境，这包括原始路径.无论如何，这对您来说并没有太多用处，因为您将无法控制下载它的去向...

You can''t. The Upload control does not let you know - even by default - about the user''s environment, and this includes the original path. It wouldn''t be a lot of use to you anyway as you will have no control over where the goes when it is downloaded either...

看看:
Silverlight文件上传 [ ^ ]-您显然需要在第二次上传时更新数据库中的信息:)

最好的问候

Have a look at:
Silverlight File Upload[^] - you obviously need to update the information in the database on the second upload :)
