如何从c#中的字符串中删除任何重复的子字符串?例如,在此字符串中:
This is a test test string
将删除重复的“测试”,创建结果:
This is a test string
或
shift+shift+shift+shift+d
“shift + shift + shift +”将被移除,导致
shift+d
答案 0 :(得分:0)
我希望你的问题本身可以通过不同的句子来删除重复的单词,并删除单词重复的字符。
using System;
using System.Collections.Generic;
using System.Linq;
namespace ConsoleApp
{
internal class Program
{
private static void Main()
{
var input = new[] {"This is TEST TEST string", "shift+shift+shift+D"};
foreach (string data in input)
{
bool contains = data.Contains((char)0x20);
Console.WriteLine(contains ? StripFromSentence(data.TrimEnd(new[] {(char) 0x20})) : StripFromWord(data));
}
Console.ReadLine();
}
private static string StripFromWord(string word)
{
char[] chr = word.ToCharArray();
var ap = new HashSet<char>();
foreach (char s in chr)
ap.Add(s);
return ap.Aggregate(string.Empty, (current, c) => current + c);
}
private static string StripFromSentence(string sentence)
{
string[] strings = sentence.Split(new[] {(char) 0x20});
var ap = new HashSet<string>();
foreach (string s in strings)
ap.Add(s);
return ap.Aggregate(string.Empty, (current, word) => current + (word + (char)0x20));
}
}
}
我希望这可以解决你的问题。
