022集—— 字符串按ascii码转数字——C#学习笔记

字符串分解为字符，字符分别转为ascii对应数字，最后数字连接起来转为字符串，具体如下：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;namespace ConsoleApp1
{public  class b{public static string StringTInt(string input){char[] values = input.ToCharArray();string newtext = "";foreach (char letter in values){// Get the integral value of the character.int value = Convert.ToInt32(letter);// Convert the decimal value to a hexadecimal value in string form.string hexOutput = String.Format("{0:X}", value);Console.WriteLine("Hexadecimal value of {0} is {1}", letter, hexOutput);newtext= newtext + Convert.ToString(value);   }Console.WriteLine(newtext);//Console.ReadLine(); return newtext; }}class c { static void Main(){ string a = "abc";string c = b.StringTInt(a);Console.WriteLine($"\"{a}\"转为数字为：{c}");Console.ReadLine();}}}
