如何比较两个字符串然后打印差异 [英] How to compare two string and then print the difference

问题描述

代表。 string s1 = jersey;



string s2 = jry;



使用asterisk打印j * r ** y $ / $


是否有任何算法比较两个字符串然后写差异。

btw我正在使用VS C＃ASP.net web应用



谢谢

for ex. string s1=jersey;

string s2=jry;

print using asterisk j*r**y

is there any algorithm to compare two string and then write the diff.
btw I'm using VS C# ASP.net web application

thanks

推荐答案

使用LINQ你可以使用EXCEPT。

这里给出一个例子 Enumerable.Except（TSource）方法（IEnumerable（TSource）） ，IEnumerable（TSource））（System.Linq） [ ^ ]

从每个字符串（或2个char数组）中生成两个enumarables与exCEPT进行比较。



示例CONSOLE APP：

With LINQ you can use EXCEPT.
An example is given here Enumerable.Except(TSource) Method (IEnumerable(TSource), IEnumerable(TSource)) (System.Linq)[^]
Make two enumarables from each string (or 2 arrays of char) compare those with EXCEPT.

Example CONSOLE APP:

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

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

            string s1 = "jersey";
            string s2 = "jry";

            char[] c1 = s1.ToCharArray();
            char[] c2 = s2.ToCharArray();

            var diff = s1.Except(s2);
            string newS1 = s1;
            foreach(var value in diff)
            {
                newS1 = newS1.Replace(value, '*');
                Console.WriteLine(value);
            }
            Console.WriteLine(newS1);
            Console.Read();
        }
    }
}

我想以下代码嘻嘻你

I think below code hip you

string s1 = "jersey";
            string s2 = "jry";
            string final = string.Empty;
            char[] aa = s1.ToCharArray();
            foreach (char aaa in aa)
            {
                final = final + "*";
            }
            char[] bb = s2.ToCharArray();
            int startindex=0;
            foreach (char bbb in bb)
            {
                foreach (char aaa in aa)
                {
                    if (s1.IndexOf(bbb, startindex) > -1)
                    {
                        final = final.Remove(s1.IndexOf(bbb, startindex), 1);
                        final = final.Insert(s1.IndexOf(bbb, startindex), bbb.ToString());
                        startindex = s1.IndexOf(bbb, startindex) + 1;
                    }
                    
                }

            }
            Response.Write(final);
