HtmlEncode仅查找一些特殊字符，并将其替换为硬编码值，此外，还另一些其他高ASCII字符(160-255)作为在此处中进行了描述.编码为实体名称的唯一方法是手动指定它们.我试了一下，围绕System.Net.WebUtility类构建了一个包装器，同时利用了.NET使用的现有Html实体数据集进行解码，从而使解码继续适用于此解决方案.我已将其托管在github上: WebUtilityWrapper .您可以按如下所示使用它:

HtmlEncode only looks for a few special characters and replaces them with hard-coded values, and additionally a few more high ASCII characters (160 - 255) as described here. The only way to encode into entity names is by specifying them manually. I gave it a shot and built a wrapper around the System.Net.WebUtility class while leveraging the existing Html entities dataset used by .NET to decode as well so that decoding continues to work with this solution. I've hosted it on github: WebUtilityWrapper. You can use it as shown below:

WebUtilityWrapper.HtmlEncode("€"); // Returns €
WebUtilityWrapper.HtmlEncode("Δ"); // Returns Δ
WebUtilityWrapper.HtmlEncode("&"); // Returns &
WebUtilityWrapper.HtmlEncode("$"); // Returns $ 
WebUtilityWrapper.HtmlEncode("€¢£¥"); // Returns €¢£¥

我已经通过编码和解码回去，然后验证我们是否获得了针对大量Unicode字符的原始字符串进行了测试.分享更多测试:

I've tested it out by encoding and decoding back and then verifying if we get the original string for a large set of unicode characters. Sharing some more tests:
