1.引用Zxing.Net
2.控制器代码
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.Mvc; using ZXing; using ZXing.Common;//一维码 using ZXing.QrCode;//二维码 using System.Drawing.Imaging;//图片保存 using System.Drawing; namespace WebApplication8.Controllers { public class DefaultController : Controller { // GET: Default public ActionResult Index() { return View(); } /// <summary> /// 生成条形码 /// </summary> /// <param name="Name"></param> /// <returns></returns> public string Code(string Name) { //设置条形码规格 EncodingOptions encod = new EncodingOptions(); //设置高 encod.Height = 120; //设置宽 encod.Width = 200; //生成条形码的图片并保存 BarcodeWriter wr = new BarcodeWriter(); //指定规格 wr.Options = encod; //指定条形码规格为EAN_13 wr.Format = BarcodeFormat.EAN_13; //生成图片 Bitmap img = wr.Write(Name); //获取文件夹的绝对路径 string filepath = Server.MapPath("/image/"); //获取当前时间 string datime = DateTime.Now.ToString("yyMMddHHmmss"); //进行图片保存 img.Save(filepath + datime + ".jpg", System.Drawing.Imaging.ImageFormat.Jpeg); //返回生成一维码图片的路径 return "/image/" + datime + ".jpg"; } /// <summary> /// 生成二维码 /// </summary> /// <param name="Name"></param> /// <returns></returns> public string QRcode(string Name) { //设置二维码规格 QrCodeEncodingOptions qr = new QrCodeEncodingOptions(); //设置编码格式,否则会乱码 qr.CharacterSet = "UTF-8"; qr.Height = 200; qr.Width = 200; //设置二维码图片周围空白边距 qr.Margin = 1; //生成条形码图片保存 BarcodeWriter wr = new BarcodeWriter(); //二维码 wr.Format = BarcodeFormat.QR_CODE; wr.Options = qr; Bitmap bit = wr.Write(Name); string filepath = Server.MapPath("/image/"); //获取当前时间 string datime = DateTime.Now.ToString("yyMMddHHmmss"); //进行图片保存 bit.Save(filepath + datime + ".jpg", System.Drawing.Imaging.ImageFormat.Jpeg); //返回生成一维码图片的路径 return "/image/" + datime + ".jpg"; } } }
3.视图代码（前台）
<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>
</head>
<body>
<div id="img1">
@*实现图片的盒子*@
</div>
<p>
显示文本<input type="text" id="text1" name="name1" value="" /> @*文本框*@
<input type="button" onclick="qqq()" name="name11" value="一维码生成" />@*一维码生成按钮*@
<input type="button" onclick="www()" name="name12" value="二维码生成" />@*二维码生成按钮*@
</p>
<script>
function qqq() {
var name1 = $("#text1").val();//获取文本框的值
$.ajax({//进行Ajax 提交到控制器 (下面有控制器方法的图片)
url: '/Default/yi?name=' + name1,//路径传参
type: 'post',
success: function (rese) {//收到返回的一维码图片地址
$("#imge1").remove();//清空盒子中图片
$("#img1").append("<img id='images' src=" + rese + " />");//在盒子中最加二维码图片显示
}
})
}
function www() {
var name2 = $("#text1").val();
$.ajax({
url: '/Default/er?name=' + name2,
type: 'post',
success: function (rese) {
$("#imge1").remove();
$("#img1").append("<img id='images' src=" + rese + " />");
}
})
}
</script>
</body>
</html>
