HttpUtility encode vs WebUtility encode

#csharp #asp #aspnet #webapi

Hello guys, Today I have learned a difference between HttpUtility.HtmlEncode and WebUtility.HtmlEncode. If you use dot net version less than 4.7 then HttpUtility.HtmlEncode encodes the regional languages. If you want to only html tags need to encode then use WebUtility.HtmlEncode.

var regionalText = "தமிழ்";
        var htmlText = "<script>alert('OK')";

        var httpUtilityRegionalText = HttpUtility.HtmlEncode(regionalText); //&#2980;&#2990;&#3007;&#2996;&#3021;
        var httpUtilityHtmlText = HttpUtility.HtmlEncode(htmlText); //&lt;script&gt;alert(&#39;OK&#39;)

        regionalText = "தமிழ்";
        htmlText = "<script>alert('OK')";

        var webUtilityRegionalText = WebUtility.HtmlEncode(regionalText); //தமிழ்
        var webUtilityHtmlText = WebUtility.HtmlEncode(htmlText); //&lt;script&gt;alert(&#39;OK&#39;)
