请教怎么将图片更新到sql的image字段中

Answer 1

转为byte类型后存入Image字段。
byte[] imagebytes=null;
FileStream fs=new FileStream(Image_path,FileMode.Open);
BinaryReader br=new BinaryReader(fs);
imagebytes=br.ReadBytes(br.Length);
SqlParameter parInput22=cmd.Parameters.Add( "@员工图片 ",SqlDbType.Image);
parInput22.Direction=ParameterDirection.Input;
cmd.Parameters[ "@员工图片 "].Value=imagebytes;
cmd.ExecuteNonQuery();
