第一步://获取当前选择的图片 this.pictureBox1.Image = Image.FromStream(this.openFileDialog1.OpenFile()); //获取当前图片的路径 string path = openFileDialog1.FileName.ToString(); //将制定路径的图片添加到FileStream类中 FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read); //通过FileStream对象实例化BinaryReader对象 BinaryReader br = new BinaryReader(fs); //通过BinaryReader类对象的ReadBytes()方法将FileStream类对象转化为二进制数组 byte[] imgBytesIn = br.ReadBytes(Convert.ToInt32(fs.Length));第二步://将图片添加到数据库中 string sql="insert into pic values(@pic)"; SqlParameter[] param = new SqlParameter[] { new SqlParameter("@pic", imgBytesIn) }; DBHelper.GetExecuteQuery(sql, param);第三步://将图片从数据库中取出 string sql="select * from pic where id=0"; SqlDataReader reader = DBHelper.GetExecuteReader(sql, null); MemoryStream mss = null; 参考下面三篇,如果不会也没有什么好说了:http://www.cnblogs.com/insus/p/4620420.htmlhttp://www.cnblogs.com/insus/p/4623507.htmlhttp://www.cnblogs.com/insus/p/4632889.html
