如何将C#中不同的单词保存到.txt中

using System;
using System.IO;
using System.Text.RegularExpressions;

string inputText = "这是一段文本，包含不同的单词。";

string[] words = Regex.Matches(inputText, @"\b\w+\b")
                    .Cast<Match>()
                    .Select(m => m.Value)
                    .ToArray();

using (StreamWriter writer = new StreamWriter("words.txt"))
{
    foreach (string word in words)
    {
        writer.WriteLine(word);
    }
}

writer.Close();

using System;
using System.IO;
using System.Text.RegularExpressions;

class Program
{
    static void Main(string[] args)
    {
        string inputText = "这是一段文本，包含不同的单词。";

        string[] words = Regex.Matches(inputText, @"\b\w+\b")
                            .Cast<Match>()
                            .Select(m => m.Value)
                            .ToArray();

        using (StreamWriter writer = new StreamWriter("words.txt"))
        {
            foreach (string word in words)
            {
                writer.WriteLine(word);
            }
        }
    }
}
