在网格视图中上传文件 [英] file uploading in grid view

问题描述

hi
我正在使用网格视图编辑模板来上传文件
我将路径存储在数据库中，并将图像存储在本地文件夹"images"中
我编写以下代码将图像保存在本地文件夹中.

hi
i am using grid view edit template for file uploading
i am storing path in database and images in local folder "images"
i write the following code to save image in local folder.

string FileName = Path.GetFileName(FileUpload1.PostedFile.FileName);
                  FileUpload1.SaveAs(Server.MapPath("images/" + FileName));

和网格视图中的代码

and code in grid viewis

<asp:TemplateField HeaderText="Image">
                    <ItemTemplate>
                       <asp:Image Width="100px" Height="100px" ImageUrl='<%# Eval("Photo") %>' runat="server" ID="image" />
                     </ItemTemplate>
                    <EditItemTemplate>
                       <asp:FileUpload ID="FileUpload1" runat="server" />
                    </EditItemTemplate>
                </asp:TemplateField>

如果我浏览了图像，则更新时效果很好
反之则显示错误


System.IO.DirectoryNotFoundException:找不到路径"D:\ EmsApp \ EmsApp \ EmsUI \ images \"的一部分.

it is working well when i updating if image is browsed
other wise it shows error


System.IO.DirectoryNotFoundException: Could not find a part of the path ''D:\EmsApp\EmsApp\EmsUI\images\''.

<big><big></big><big>i think that this can be solved by seeting path to image''s path 
how can i set this.</big></big>

请任何人帮助我.


谢谢

推荐答案

它看起来像是路径引用的问题.尝试使用此技巧:解析多文件夹WebSite中的路径 [ ^ ]

确保正确引用了路径，并且错误应该消失了.

It looks like an issue of path reference. Try using this tip: Resolving Paths in a Multi-Folder WebSite[^]

Make sure the path is correctly referred and the error should go away.
