C#.NET GB2312编码转化为中文

代码：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;

namespace GB2312ConvertChinese
{
    class Program
    {
        static void Main(string[] args)
        {
            string content = "/HTC Butterfly X920e是刚刚推出不久的一款智能手机，该机的5.0英寸大屏&";
            Console.WriteLine(GBKToChinese(content));
            Console.ReadKey();
        }
        static string GBKToChinese(string content)
        {
            string pattern = "&#(.+?);";          
            if (!Regex.IsMatch(content, pattern))
                return content;
            MatchCollection collection = Regex.Matches(content, pattern);
            foreach (Match item in collection)
            {
                string GBK_Code = item.Value;
                string GBK_Value = item.Groups[1].Value;
                string chinese = ((char)Convert.ToInt32(GBK_Value, 10)).ToString();
                content = content.Replace(GBK_Code, chinese);
            }
            return content;
        }
    }
}

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    class Program
    {
        //获得GB2312编码。
        static void Main(string[] args)
        {
            string str = "研究中心";
            StringBuilder sb = new StringBuilder();
            foreach (char c in str)
                sb.AppendFormat("&#{0};", Convert.ToString((int)c, 10));
            Console.WriteLine(sb.ToString());
            Console.ReadKey();
        }
    }
}

 

参考：请问关于\u开头的汉字编码是什么类型的编码，c#怎样转换

URL：http://www.phpfans.net/ask/MTcyNzYzNw.html 

unicode字符
如果是这样的string str = "\u5317\u4eac";
那直接输出就可以了
如果这个字符串是从其它地方得到的话，就这样：

C# code

    
    
    
    

     
     
     
      
     
     
     
     string
     
     
     
      str 
     
     
     
     =
     
     
     
      
     
     
     
     "
     
     
     
     \\u5317\\u4eac
     
     
     
     "
     
     
     
     ; 
     
     
     
     string
     
     
     
     [] temp 
     
     
     
     =
     
     
     
      str.Split(
     
     
     
     new
     
     
     
      
     
     
     
     string
     
     
     
     [] { 
     
     
     
     "
     
     
     
     \\u
     
     
     
     "
     
     
     
      }, StringSplitOptions.RemoveEmptyEntries); 
     
     
     
     for
     
     
     
      (
     
     
     
     int
     
     
     
      i 
     
     
     
     =
     
     
     
      
     
     
     
     0
     
     
     
     ; i 
     
     
     
     <
     
     
     
      temp.Length; i
     
     
     
     ++
     
     
     
     ) temp[i] 
     
     
     
     =
     
     
     
      ((
     
     
     
     char
     
     
     
     )Convert.ToInt32(temp[i], 
     
     
     
     16
     
     
     
     )).ToString(); 
     
     
     
     string
     
     
     
      result 
     
     
     
     =
     
     
     
      
     
     
     
     string
     
     
     
     .Join(
     
     
     
     ""
     
     
     
     , temp); Console.WriteLine(result); 
    
    
    
    

 

要从汉字转成unicode编码：

C# code

    
    
    
    

     
     
     
      
     
     
     
     string
     
     
     
      str 
     
     
     
     =
     
     
     
      
     
     
     
     "
     
     
     
     北京
     
     
     
     "
     
     
     
     ; StringBuilder sb 
     
     
     
     =
     
     
     
      
     
     
     
     new
     
     
     
      StringBuilder(); 
     
     
     
     foreach
     
     
     
      (
     
     
     
     char
     
     
     
      c 
     
     
     
     in
     
     
     
      str) sb.AppendFormat(
     
     
     
     "
     
     
     
     \\u{0}
     
     
     
     "
     
     
     
     , Convert.ToString((
     
     
     
     int
     
     
     
     )c, 
     
     
     
     16
     
     
     
     )); Response.Write(sb.ToString());
