//把图片读到pictureBox，再写入数据库

SqlConnection conn=new SqlConnection(@"data source=chenyuming2004\VSdotNET;uid=sa;pwd=cym;database=lhf");
conn.Open();
SqlCommand cmd=new SqlCommand("insert into fuser values ('1a','1b',@i)",conn);
byte[] ib=new Byte[60000];
FileStream fs=new FileStream(@"D:\windows temp\temp\1.jpg",FileMode.Open ,FileAccess.Read );
fs.Read(ib,0,60000);
cmd.Parameters.Add("@i",SqlDbType.Image,(int)fs.Length);
cmd.Parameters["@i"].Value=ib;
cmd.ExecuteNonQuery();
conn.Close();

//从数据库读图片到picturebox

SqlConnection conn=new SqlConnection(@"data source=chenyuming2004\VSdotNET;uid=sa;pwd=cym;database=lhf");
conn.Open();
SqlCommand cmd=new SqlCommand("select 照片 from fuser where password='1b'",conn);
SqlDataReader reader=cmd.ExecuteReader();
reader.Read();
MemoryStream buf=new MemoryStream((byte[])reader[0]);
Image image=Image.FromStream(buf,true);
pictureBox1.Image=image;
