Node.js使用express解析cookie

Node.js、、、、

首先使用cookieParser()解析请求头里的Cookie, 并用cookie名字的键值对形式放在 req.cookies 你也可以通过传递一个secret 字符串激活签名了的cookie 。
app.use(express.cookieParser());
app.use(express.cookieParser('some secret'));

下面是读写cookie的代码


var express = require('express');
var app = express();
app.get('/readcookie',function(req,res){
    res.send('req.cookies.name:' + req.cookies.name);
});
app.get('/writecookie',function(req,res){
    res.cookie('name', 'I'm a cookie', 60000);
    res.send("cookie saved");
});
app.listen(3000);
console.log('listening on port 3000');

.Net mvc自定义字符串截取（考虑全角/半角）

.NET MVC 
public static class HtmlHelpers
{
  public static string Truncate(this HtmlHelper helper, string inputString, int length)
  {
    string tempString = string.Empty;
    for (int i = 0, tempIndex = 0; i < inputString.Length; ++i, ++tempIndex)
    {
      if (System.Text.Encoding.UTF8.GetBytes(new char[] { inputString[i] }).Length > 1)
      {
        ++tempIndex;
      }
      if (tempIndex >= length)
      {
        tempString += "...";
        break;
      }
      tempString += inputString[i];
    }
    return tempString;
  }
}

C#中汉字排序简单示例（拼音/笔划）

C# 

class Program
    {
        static void Main(string[] args)

            string[] arr = { "趙（ZHAO）", "錢（QIAN）", "孫（SUN）", "李（LI）", "周（ZHOU）", "吳（WU）", "鄭（ZHENG）", "王（WANG）"};

            Array.Sort(arr);
            Console.WriteLine("按发音排序:");
            for (int i = arr.GetLowerBound(0); i <= arr.GetUpperBound(0); i++)
                Console.WriteLine("[{0}]:t{1}", i, arr.GetValue(i));
            Console.WriteLine();

            Console.ReadKey();
        }
