一步一步学习Winform系列3：新增记录——DataGridView的属性和数据banding

FileStream fs = new FileStream(pathName, System.IO.FileMode.Open, System.IO.FileAccess.Read);

byte[] buffByte = new byte[fs.Length];

fs.Read(buffByte, 0, (int)fs.Length);

fs.Close();                                        //数据库字段为image类型，将图片转化为byte[]，保存到数据库

SqlConnection   db   =   new   SqlConnection(strConn);

db.Open();

string   strSQL   =   "INSERT   INTO   shujuktable (name)   values   (@name) ";

SqlCommand   cmd   =   new   SqlCommand(strSQL,   db);

cmd.Parameters.Add( "@name",   SqlDbType.Image);

cmd.Parameters[ "@name"].Value   =   buffByte;

cmd.ExecuteNonQuery();                                       //保存图片的过程
