使用listview和fileupload在db中存储映像路径

Question

我想将图像存储在带有列标题，新闻，图像的表格的数据库中。任何人都可以帮我在哪里放置c＃代码，即在什么处理程序中，以便它上传到新闻和标题所属的同一列。

请帮助，将是一个真正的大帮助。请

ASPX：

            <asp:Parameter Name="Id" Type="Int32" />
        </UpdateParameters>
    </asp:SqlDataSource>

代码隐藏：

  protected void SqlDataSource1_Inserting(object sender, SqlDataSourceCommandEventArgs e)
{
FileUpload FileUpload1 = (FileUpload)ListView1.InsertItem.FindControl("FileUpload1");
string virtualFolder = "~/NewsPics/";
string physicalFolder = Server.MapPath(virtualFolder);
string fileName = Guid.NewGuid().ToString();
string extension = System.IO.Path.GetExtension(FileUpload1.FileName);
FileUpload1.SaveAs(System.IO.Path.Combine(physicalFolder, fileName + extension));
string ImageUrl = virtualFolder + fileName + extension;

SqlDataSource1.InsertParameters["ImageUrl"].DefaultValue = ImageUrl;

}

我试过这个但没有结果。该文件被转移到文件系统[“NewsPics”]，但路径未保存在数据库中。
