编辑绑定数据库照片分页显示
 // 显示分类及一张照片
      public DataSet ShowCategory()
    {
        SqlConnection conn = new SqlConnection(connstr);
        string sqlstr = "select A.*,"
                    + "(select count(*) from Photo B where B.CategoryID = A.ID) AS p_num,"
                    + "(select top 1 C.url from Photo C where C.CategoryID = A.ID) AS url "
                    + "from Photo_Category AS A "
                    + "where A.C_Status = '公开' "
                    + "and  A.ID in "
                    + "(select CategoryID from Photo)";
        SqlDataAdapter da = new SqlDataAdapter(sqlstr,conn);
        DataSet ds = new DataSet();
        try
        {
            conn.Open();
            da.Fill(ds,"P_Category");
        }
        catch(Exception ex)
        {
            throw new Exception(ex.Message,ex);
        }
        finally
        {
            conn.Close();
        }
        return ds;
    }
  // 显示分类内的相册
      public DataSet ShowPhoto(int Category)
    {
        SqlConnection conn = new SqlConnection(connstr);
        string sqlstr = "select * from Photo where CategoryID = @CategoryID";
        SqlDataAdapter da = new SqlDataAdapter(sqlstr,conn);
        da.SelectCommand.Parameters.Add("@CategoryID",SqlDbType.Int,4).Value = Category;
        DataSet ds = new DataSet();
        try
        {
            conn.Open();
            da.Fill(ds,"Photo");
        }
        catch(Exception ex)
        {
            throw new Exception(ex.Message,ex);
        }
        finally
        {
            conn.Close();
        }
        return ds;
    }
  // 编辑图片信息
    public int EditPhoto(int id, string title, string description)
    {
        SqlConnection conn = new SqlConnection(connstr);
        string sqlstr = "update Photo set Title=@title,Descript=@description where ID=@id";
        SqlCommand cmd = new SqlCommand(sqlstr,conn);
        cmd.Parameters.Add("@id",SqlDbType.Int,4).Value = id;
        cmd.Parameters.Add("@title",SqlDbType.VarChar,50).Value = title;
        cmd.Parameters.Add("@description",SqlDbType.VarChar,100).Value = description;
        int result = -1;
        try
        {
            conn.Open();
            result = cmd.ExecuteNonQuery();
        }
        catch (Exception ex)
        {
            throw new Exception(ex.Message, ex);
        }
        finally
        {
            conn.Close();
        }
        return result;
    }
//分页功能
