一，上传并存入sqlserver
 数据库结构
  create table test
  {
     id identity(1,1),
     FImage image
  }
  相关的存储过程
  Create proc UpdateImage
  (
     @UpdateImage Image
  )
  As
  Insert Into test(FImage) values(@UpdateImage)
  GO

在upphoto.aspx文件中添加如下:
<input id="UpPhoto" name="UpPhoto" runat="server" type="file">
<asp:Button id="btnAdd" name="btnAdd" runat="server" Text="上传"></asp:Button>

然后在后置代码文件upphoto.aspx.cs添加btnadd按钮的单击事件处理代码:
private void btnAdd_Click(object sender, System.EventArgs e)
{
        //获得图象并把图象转换为byte[]
        HttpPostedFile upPhoto=UpPhoto.PostedFile;
        int upPhotoLength=upPhoto.ContentLength;
        byte[] PhotoArray=new Byte[upPhotoLength];
        Stream PhotoStream=upPhoto.InputStream;
        PhotoStream.Read(PhotoArray,0,upPhotoLength);

        //连接数据库
        SqlConnection conn=new SqlConnection();
