推荐答案

using System;
using System.Text.RegularExpressions;

/// <summary>
/// Methods to remove HTML from strings.
/// </summary>
public static class HtmlRemoval
{
    /// <summary>
    /// Remove HTML from string with Regex.
    /// </summary>
    public static string StripTagsRegex(string source)
    {
	return Regex.Replace(source, "<.*?>", string.Empty);
    }

    /// <summary>
    /// Compiled regular expression for performance.
    /// </summary>
    static Regex _htmlRegex = new Regex("<.*?>", RegexOptions.Compiled);

    /// <summary>
    /// Remove HTML from string with compiled Regex.
    /// </summary>
    public static string StripTagsRegexCompiled(string source)
    {
	return _htmlRegex.Replace(source, string.Empty);
    }

    /// <summary>
    /// Remove HTML tags from string using char array.
    /// </summary>
    public static string StripTagsCharArray(string source)
    {
	char[] array = new char[source.Length];
	int arrayIndex = 0;
	bool inside = false;

	for (int i = 0; i < source.Length; i++)
	{
	    char let = source[i];
	    if (let == ''<'')
	    {
		inside = true;
		continue;
	    }
	    if (let == ''>'')
	    {
		inside = false;
		continue;
	    }
	    if (!inside)
	    {
		array[arrayIndex] = let;
		arrayIndex++;
	    }
	}
	return new string(array, 0, arrayIndex);
    }
}

using System;
using System.Text.RegularExpressions;

class Program
{
    static void Main()
    {
	const string html = "<p>There was a .NET programmer " +
	    "and he stripped the HTML tags.</p>";

	Console.WriteLine(HtmlRemoval.StripTagsRegex(html));
	Console.WriteLine(HtmlRemoval.StripTagsRegexCompiled(html));
	Console.WriteLine(HtmlRemoval.StripTagsCharArray(html));
    }
}

这给出了

This gives

<p>There was a <b>.NET</b> programmer " +
        "and he stripped the <i>HTML</i> tags.</p>

有一个.NET程序员，他剥离了HTML标记.

There was a .NET programmer and he stripped the HTML tags.
