Question

我正在尝试为类项目构建一个网络钓鱼扫描程序，我一直试图将一个电子邮件保存在一个文本文件中，以便正确地复制到一个数组中以便以后处理。我想要的是每个单词都在其自己的数组索引中。

以下是我的示例电子邮件：

Subject: Insufficient Funds Notice
Date: September 25, 2013

我不想要任何标点符号，只需要单词和数字。

这是我到目前为止编写的代码。

    StreamReader sr1 = new StreamReader(lblDisplaySelectedFilePath.Text);
    string line = sr1.ReadToEnd();
    words = line.Split(' ');
    int wordslowercount = 0;
    foreach (string word in words)
    {
        words[wordslowercount] = word.ToLower();
        wordslowercount = wordslowercount + 1;   
    }

上述代码的问题在于我不断收到串在一起的文字和/或有＆＃34; \ r＆＃34;或＆＃34; \ n＆＃34;他们在阵列中。这是一个我不想要的数组中的例子。

"notice\r\ndate:"不想要\ r，\ n或者：\ n。这两个词也应该在不同的索引中。

Answer 1

正则表达式\W将允许您拆分字符串并创建单词列表。这使用了单词边界，因此它不包括标点符号。

Regex.Split(inputString, "\\W").Where(x => !string.IsNullOrWhiteSpace(x));

Answer 2

using System;
using System.Text.RegularExpressions;

public class Example
{
    static string CleanInput(string strIn)
    {
        // Replace invalid characters with empty strings. 
        try {
           return Regex.Replace(strIn, @"[^\w\.@-]", "", 
                                RegexOptions.None, TimeSpan.FromSeconds(1.5)); 
        }
        // If we timeout when replacing invalid characters,  
        // we should return Empty. 
        catch (RegexMatchTimeoutException) {
           return String.Empty;   
        }
    }
}

Answer 3

使用line.Split(null)会在空白处分开。来自C# String.Split method documentation：

如果separator参数为null或不包含字符，则假定空格字符为分隔符。空格字符由Unicode标准定义，如果将它们传递给Char.IsWhiteSpace方法，则返回true。
