Asp.net多个文件上传

问题描述：

您好

我从ASP.Net网络表单上传多个文件。我们有一个页面有多个面板

来自面板2我附加5个文件，我从5个面板提交页面

i我在会话中保存文件信息并在Ispostback中分配给FileUpload

ObjFileUploader1 =（FileUpload）Session [FileUpload1];

ObjFileUploader2 =（FileUpload）Session [FileUpload2];

ObjFileUploader3 =（FileUpload）Session [FileUpload3];

ObjFileUploader4 =（FileUpload）会话[FileUpload4];

ObjFileUploader5 =（FileUpload）会话[FileUpload5];

提交按钮我要迭代通过ObjFileUploader1，ObjFileUploader2，ObjFileUploader3，ObjFileUploader4，ObjFileUploader5

保存在数据库和服务器中

请求。由于我在第5小组，文件无法正常工作

目前我在做什么下面，重复的代码

if（temp！= 0&& ObjFileUploader1！= null&& ObjFileUploader1.HasFile）

{

保存数据库和上传文件

}

if（temp！= 0&& ObjFileUploader2！= null&& ObjFileUploader2.HasFile）

{

保存数据库和上传文件

}

if（temp！= 0&& ObjFileUploader3！= null&& ObjFileUploader3.HasFile）

{

保存数据库和上传文件

}

请帮帮我

我尝试过：

Request.file集合不工作

ObjFileUploader1 = (FileUpload)Session["FileUpload1"];
ObjFileUploader2 = (FileUpload)Session["FileUpload2"];
ObjFileUploader3 = (FileUpload)Session["FileUpload3"];
ObjFileUploader4 = (FileUpload)Session["FileUpload4"];
ObjFileUploader5 = (FileUpload)Session["FileUpload5"];

to save in DB and Server

request.files not working because of i am in panel 5

Currently i am doing like below , repetitive code

{
Save DB and upload file
}

Please help me

答

我不完全理解这个问题，但我认为你正在寻找循环上传控件。把它们放在占位符中

I don't fully understand the question but I think you are looking to loop through your upload controls. Put them in a placeholder

<asp:PlaceHolder ID="placeUplode" runat="server">
    <asp:FileUpload ID="ObjFileUploader1" runat="server" />
    <asp:FileUpload ID="ObjFileUploader2" runat="server" />
    <asp:FileUpload ID="ObjFileUploader3" runat="server" />
    <asp:FileUpload ID="ObjFileUploader4" runat="server" />
    <asp:FileUpload ID="ObjFileUploader5" runat="server" />
</asp:PlaceHolder>

然后在您的代码中访问它们

then in your code access them like this

foreach(FileUpload uploader in placeUplode.Controls.OfType<FileUpload>())
{
    System.Diagnostics.Debug.WriteLine(uploader.ID);
    if (uploader.HasFile)
    {
        // your code here
    }
}
