推荐答案
试试这个
try this
HttpFileCollection hfc = Request.Files;
for (int i = 0; i < hfc.Count; i++)
{
HttpPostedFile hpf = hfc[i];
if (hpf.ContentLength > 0)
{
string FileName = hpf.FileName;
hpf.SaveAs(SavePath + "\\" + Path.GetFileName(FileName));
}
}
HttpFileCollection提供对客户上传的文件的访问和组织。
HttpFileCollection Provides access to and organizes files uploaded by a client.
