Answer 2

设计里拖一个FileUpload和以个Button
然后在Button_Click事件里写
string FileName = FileUpload1.PostedFile.FileName.Substring(FileUpload1.PostedFile.FileName.LastIndexOf(@"/")+1);//获取文件名字，前面的盘符路径省略；
FileUpload1.PostedFile.SaveAs(Server.MapPath("要上传的盘符名" + FileName));

Answer 3

FileUpload1.SaveAs(绝对路径)

Answer 4

别人回答了，怎么不给分。

Answer 5

前台托一个fileUpload控件 后台就是楼上的写的
