使用哈希集删除重复的字符。
这是字符串-
string myStr = "kkllmmnnoo";
现在,使用HashSet将字符串映射到char。这将从字符串中删除重复的字符。
var unique = new HashSet<char>(myStr);
让我们看完整的例子-
using System;
using System.Linq;
using System.Collections.Generic;
namespace Demo {
class Program {
static void Main(string[] args) {
string myStr = "kkllmmnnoo";
Console.WriteLine("Initial String: "+myStr);
var unique = new HashSet<char>(myStr);
Console.Write("New String after removing duplicates: ");
foreach (char c in unique)
Console.Write(c);
}
}
}输出结果
Initial String: kkllmmnnoo New String after removing duplicates: klmno
