C# convert a string to unicode encoding

Question

I need to convert a string i.e. "hi" to & #104;& #105; is there a simple way of doing this? Here is a website that does what I need. http://unicode-table.com/en/tools/encoder/

You want the HTML hex values for the string, or do you actually want to switch from one encoding to another? — Ron Beyer, Sep 18 '15 at 01:56
@Andy you may want to put your code (even in JS) in the post to show what you've tried. (Also converting the JS you've added in comment to C# should be trivial - you may as well explain what problem you've faced when converting). — Alexei Levenkov, Sep 18 '15 at 02:06
sorry had a hard time explaining this. I appreciate the help! — Andy, Sep 18 '15 at 02:14

Try this:

var s = "hi";
var ss = String.Join("", s.Select(c => "&#" + (int)c + ";"));

Try this:

string myString = "Hi there!";
string encodedString = myString.Aggregate("", (current, c) => current + string.Format("&#{0};", Convert.ToInt32(c)));

Fancy, but one should not build long string with string concatenation... If rebuilding `String.Join` with `Enumerable.Aggregate` you should still use `StringBuilder`... – Alexei Levenkov Sep 18 '15 at 02:07

Based on the answer to this question:

    static string EncodeNonAsciiCharacters(string value)
    {
        StringBuilder sb = new StringBuilder();
        foreach (char c in value)
        {
            string encodedValue = "&#" + ((int)c).ToString("d4"); // <------- changed
            sb.Append(encodedValue);
        }
        return sb.ToString();
    }
