C#类库: public class YZM { public string YZMcode = String.Empty; public byte[] load() { Bitmap bit = , );//画布大小 Graphics g = Graphics.FromImage(bit);//创建绘制对象,告诉它往哪张图片上绘制 try { Random r = new Random(); Color color1 = Color.FromArgb(r.Next(, ), r.Next(,…
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&…
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"; ; , , )…
1.生成验证码类 using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Web.Mvc; using System.IO; using System.Drawing; using System.Web; namespace SimpleNews.FrontEnd { public class ToolController : MyControllerBa…
