C# 使用fileupload控件在数据库中上载文件

我在asp.net页面上有一个FileUpload控件和一个image控件，如下所示：

<tr>
                <td>&nbsp;</td>
                <td align="left">
                     <asp:Image ID="profileimage" runat="server" ImageUrl="~/Images /images2.jpg" 
                     Width="150px" Height="150px" />
                </td>
                <td>&nbsp;</td>
                <td colspan="2" align="left">
                    <asp:FileUpload ID="Fu" runat="server" Width="550px" />
                </td>
            </tr>

现在，如何使用代码隐藏访问fileupload控件中上载的文件路径并将其存储在数据库中，请尝试：

protected void btnSubmit_Click(object sender, EventArgs e) 
 {
  if (Fu.HasFile) {
  string filepath = Fu.PostedFile.FileName;
  //save the file to the server
  Fu.PostedFile.SaveAs(Server.MapPath(".\\") + file);
  lblStatus.Text = "File Saved to: " + Server.MapPath(".\\") + file;

 }
} 

尝试：

使用此代码：

protected void btnSubmit_Click(object sender, EventArgs e) 
{
   foreach (UploadedFile upload in Fu.UploadedFiles)
                {
                    Fu.TargetFolder = "/Attachment/ClientProfile";

                    path = Server.MapPath(Fu.TargetFolder) + "\\" + upload.GetName();
                    upload.SaveAs(path);

                }
//Here give ImageName=path to save in database.
}

使用此代码：

protected void btnSubmit_Click(object sender, EventArgs e) 
{
   foreach (UploadedFile upload in Fu.UploadedFiles)
                {
                    Fu.TargetFolder = "/Attachment/ClientProfile";

                    path = Server.MapPath(Fu.TargetFolder) + "\\" + upload.GetName();
                    upload.SaveAs(path);

                }
//Here give ImageName=path to save in database.
}
