asp.net将图片转成二进制存入数据库

一、代码如下

  int code = int.Parse(this.TextBox1.Text);//图片编码
         string value = this.FileUpload1.PostedFile.FileName.ToString();//图片路径
         string type = value.Substring(value.LastIndexOf(".") + );
         FileStream fs = File.OpenRead(value);
         byte[] content = new byte[fs.Length];
         fs.Read(content, , content.Length);
         fs.Close();

         string sqlconfrom = System.Web.Configuration.WebConfigurationManager.ConnectionStrings["sqlConnectionStrings"].ToString();
         SqlConnection con = new SqlConnection(sqlconfrom);
         string sql = " insert into Image_Table values ( '1',@content,@code ) ";

         SqlCommand cmd = new SqlCommand(sql, con);
         cmd.Parameters.Add(new SqlParameter("@content", SqlDbType.Image));
         cmd.Parameters["@content"].Value = content;

         cmd.Parameters.Add(new SqlParameter("@code", SqlDbType.Int));
         cmd.Parameters["@code"].Value = code;
         con.Open();
         int result = cmd.ExecuteNonQuery();
         if (result > )
         {
             Response.Write("插入成功！");
         }
         con.Close();
