Converting string to Unicode characters

Question

I'm trying to Convert a string in to a series of unicode characters.
for expample : if I have a string that contains "Ñ", the unicode I want would be this "U+00D1".
Edit
thank you everyone for your time. What I wanted was the hexadecimal representative of the unicode character no the character itself encoded in unicode.

You mean, you want the hexadecimal representation of each unicode character? — maf-soft

If I understand correctly, you are starting from a .NET string instance. That is not "a UTF-8 string". C# and .NET strings are based on char values which represent UTF-16 code units. — Jeppe Stig Nielsen

Try this:

    string input = "nsa";
    var result = input.Select(t => string.Format("U+{0:X4} ", Convert.ToUInt16(t))).ToList();

Or with nicer formatting (C# 6):

    string input = "nsa";
    var result = input.Select(t => $"U+{Convert.ToUInt16(t):X4} ").ToList();

Thank you. I'm using c# 4 and it seems this code needs c# 6 :(

Keep both versions of the string formatting. The future is with the interpolated strings.

Why not simply use (ushort)t instead of Convert.ToUInt16(t)?

That's also an option

Note that if the string contains code points over U+FFFF, like "abc\U00012345def" in C#, then this method will get the hex values of the surrogate pairs, not of the characters themselves. This may be exactly what you want, of course. If not, use the StringInfo class to iterate over the so-called text elements, and use the char.ConvertToUtf32 on the "text element" to get the numeric value(s).

If you are not asking about the algorithm itself, then just use Encoding.Convert.
