C#将图片存放到SQL SERVER数据库中的方法

//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));

//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);

//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;if (reader.Read()){  byte[] bytes = (byte[])reader["pic"];  mss = new MemoryStream(bytes);}this.pictureBox2.Image = Image.FromStream(mss);
