如何在ASP.NET中使用具有多个文件上载控制器（如fileupload1，fileupload2，fileupload3）的多个文件上载（任何文件） [英] How to use multiple files uploading(any files) with multiple file upload controllers(like fileupload1, fileupload2, fileupload3) in ASP.NET
问题描述
我想保存文件上载控制器各自的数据库中的所有文件路径。我的意思是当我从fileupload1中选择3个文件时，这些文件作为带有文件路径的记录存储在一个表中，id.Same就像存储的fileupload2文件一样另一种形式与Path，id.I is usinf 7文件上传控制器单击按钮。
我尝试过：

试试这个
< pre lang =C＃> protected void Fileupload（）
{
< span class =code-keyword> if （fileUpload.HasFile） // 如果有任何文件，请检查BEEN SELECTED。
{
List< HttpPostedFile> files = new List< HttpPostedFile>（）;
dynamic fileUploadControlDynamic = fileUpload;
foreach （HttpPostedFile文件 in fileUploadControlDynamic.PostedFiles）
{
files.Add（file） ;
}
int countInControl2 = files.Count;
使用HttpPostedFile你可以做任何对象..
I want to save all file paths in Database respective of fileupload controllers.I mean When i select 3 files from fileupload1..these files are stored in one table as record with file path,id.Same like that fileupload2 files stored in another form with Path,id.I am usinf 7 File upload controllers in single button click.
What I have tried:
