Asp.net无法将图像从浏览器保存到本地计算机

Question

我有一个项目网站使用我的CodeFile从本地浏览器照片然后保存路径文件图像数据库成功。但在我的开发人员项目主机，你不能插入路径文件图像到我的数据库。虽然本地机器上的项目运行得很好。 有人能帮我吗。 谢谢你们 这是我的大块代码：

HTML CODE：

<%@ Page Title="" Language="C#" MasterPageFile="~/ad/Admin.Master" AutoEventWireup="true" CodeFile="EditProduct.aspx.cs" Inherits="EditProduct" %>

<asp:Image ID="Image1" runat="server" Height="91px" Width="96px" />
<asp:FileUpload ID="FileUpload1" runat="server" /></td>
