Q：对SQL   server数据库里取image类型怎么取???

A：把aspx的html元素去掉，然后页面中调用以下函数。这个页面返回的就是图片

private void DownloadImage(string FileID)
        ...{
            using (System.Data.SqlClient.SqlConnection conn = new System.Data.SqlClient.SqlConnection())
            ...{
                conn.ConnectionString = ".....";
                conn.Open();

                using(System.Data.SqlClient.SqlCommand command=conn.CreateCommand())
                ...{

                    command.CommandText=string.Format("select ImageSize,Image from tablexxx where id='{0}'", FileID);

                    System.Data.SqlClient.SqlDataReader reader=command.ExecuteReader();

                    try
                    ...{
                        if(reader.Read())
                        ...{
                   
                            int size=reader.GetInt32(0);
                            byte[] buffer=new byte[size];

                            reader.GetBytes(1,0,buffer,0,size);

                            this.Response.BinaryWrite(buffer);
                        }
                    }
                    catch(Exception  ex)
                    ...{
                        this.Response.Write(ex.Message);
                    }
                    finally
                    ...{
                        reader.Close();
                    }
                }
                conn.Close();
            }
        }
