从文件夹中删除图像时出错 [英] I have an error when I delete an image from folder

问题描述

protected void LinkButtondelete_Command(object sender, CommandEventArgs e)
        {
foreach(DataListItem item in DataListAttachfile.Items)
            {
                    string vitualpath = System.Configuration.ConfigurationManager.AppSettings["UploadPath"].ToString() + DateTime.Now.Year.ToString() + "/" + DateTime.Now.Month.ToString() + "/" + DateTime.Now.Day.ToString() + "/" + att.Duongdanfile;
                    string savepath = HttpContext.Current.Server.MapPath("/" + vitualpath);                    
                    File.Delete(MapPath(vitualpath));
            }
}

我的尝试：

What I have tried:

<asp:LinkButton ID="LinkButtondelete" runat="server" CommandArgument='<%# Eval("id") %>' CommandName="Select" CausesValidation="false"
                                         OnCommand="LinkButtondelete_Command">Delete</asp:LinkButton>

推荐答案

您需要设置要删除的文件夹的权限，以便用于运行Web服务的身份可以删除那里的文件。

You need to set the permissions on the folder you're deleting from so, that identity used for running your webservice is allowed to delete files there.
