您尝试使用与您读取的路径不同的路径保存它：
Server.MapPath（“~/upload Images”+fu.FileName）！= 当使用FileUpload控件选择文件时，然后在postback上，使用文件的HttpPostedFile
对象初始化PostedFile
属性。由于http请求
无法维护状态，因此它会释放其状态

希望这对您有所帮助。在aspx页面中，使用updatepanel控件保存生成的ID。

根据您的gridview进行更新
**clientmode=“Static”在此处删除everiwhere**
**不删除编辑模式**
--%>
**使用上传。删除错误属性**
**AutoPostBack=“True”CommandArgument=''ClientIDMode=“Static”**
**将“更新”按钮置于外部以更新所有列**
//.aspx.cs
受保护的void b更新\u单击（对象发送方，事件参数e）
{
foreach（gvaricle.rows中的GridViewRow行）
{
文件上传fu=
row.FindControl（“fileupload”）作为fileupload；
bool ok=false；
if（fu！=null&&fu.HasFile）
{
尝试
{
//这里可能有问题。
//进程需要权限才能写入此文件夹
//此外，建议使用fu.PostedFile进行一些检查
SaveAs（Server.MapPath（“~/images/”+fu.FileName））；
ok=正确；
}
捕获（例外情况除外）
{
ok=假；
}
}
如果（确定）
{
//更新数据库表和GridViewRow图像字段。
}
}
}
我认为在foreach
循环中的CreateDetailSave
方法中，您正在将filename
保存为fileupload.Hasfile
，它将始终返回true或false。这就是为什么它总是返回false：

正如@Ruban.J所说，“FileUpload
控件将无法与异步回发一起工作”
这意味着每当发生回发文件上载丢失它的状态[其文件]时，它总是会遇到更新面板

您可以匹配键值来决定哪一个文件是哪一行的，并将其保存到数据库。给定的代码有一些严重错误，而且还不完整。在我这边真的很难复制。无论如何，t
