首先,在项目模型(Model)层中建立一个生成图片验证码的类ValidationCodeHelper,代码如下: public class ValidationCodeHelper { //用户存取验证码字符串 public string validationCode = String.Empty; Random ram = new Random(); Graphics g = null; ; ; public string FontFace = "Consolas"; ; , , )
本着简洁直接,我们就直奔主题吧! 下面是一个生成数字和字母随机组合的验证码类源代码: using System; using System.Drawing; using System.Drawing.Imaging; using System.Web.UI; using System.Drawing.Drawing2D; using System.IO; namespace Forcheng.Code { /// <summary> /// 生成验证码的类 /// </summary&
适用于自定义的验证码类! <?php/* * To change this license header, choose License Headers in Project Properties.* To change this template file, choose Tools | Templates* and open the template in the editor.*/Class Image{private $img;public $width = 85;public $hei
一般处理程序生成简单的图片验证码并通过html验证用户输入的验证码是否正确 最近没事研究了下验证码的的动态生成及通过cookie实现HTML页面对用户输入的验证码的校验,简要如下: 1.写了一个简单的验证码后台生成页面,代码如下: using System;using System.Collections.Generic;using System.Drawing;using System.Linq;using System.Text;using System.Web; using S
1. 新建一个Validate.aspx,然后在Validate.aspx.cs编写代码: using System; using System.Collections; using System.ComponentModel; using System.Data; using System.Web; using System.Drawing; using System.Web.SessionState; using System.Web.UI; using System.Web.UI.WebC
