Converting & to & etc

问题:

I want to convert & to &, " to " etc. Is there a function in c# that could do that without writing all the options manually?

回答1:

System.Web.HttpUtility.HtmlDecode()

Edit: Note from here that "To encode or decode values outside of a web application, use..."

System.Net.WebUtility.HtmlDecode()

回答2:

Use the static method

HttpUtility.HtmlEncode

to change & to & and " to ". Use

HttpUtility.HtmlDecode

to do the reverse.

For .NET < 4 simple encoder

    public static string HtmlEncode(string value)
    {
        return value.Replace("&", "&amp;").Replace("<", "&lt;").Replace(">", "&gt;").Replace("\"", "&quot;").Replace("'", "&apos;");
    }
