HexToStr转ToStrHex

Question

已有HexToStr 现在在求StrToHex

public static string HexToStr(string HexStr)
{
    string text = string.Empty;
    for (int i = 1; i <= HexStr.Length; i += 2)
    {
        string text2 = Strings.Mid(HexStr, i, 2);
        if (text2.CompareTo("80") > 0)
        {
            i += 2;
            text2 += Strings.Mid(HexStr, i, 2);
        }
        text2 = "0x" + text2;
        int charCode = Convert.ToInt32(text2, 16);
        text += Strings.ChrW(charCode);
    }
    return text;
}

Answer 1

using System;
using System.Text;
namespace HelloWorldApplication
{
   class HelloWorld
   {
       static string StrToHex(string str)
       {
           var b = Encoding.Default.GetBytes(str); //如果是中文，你这里相应用别的编码，比如 GB 或者 UTF8
           return BitConverter.ToString(b).Replace("-", "");
       }
      static void Main(string[] args)
      {
         Console.WriteLine(StrToHex("Hello World!"));
      }
   }
}
