Convert string to unicode in C#?

Question

How can I get the unicode values (from the code column) if I have the string? For example, for passing the empty space " " I would like to get the value U+0020. I found this approach:

byte[] asciiBytes1 = Encoding.ASCII.GetBytes(" ");

But this returns me the value from the decimal column.

A string consists of chars, which you can cast to a short (or int). This will give you more characters than ASCII (which has codes from 0 to just 127). But then you may run into "surrogate pairs" ... — Hans Keﬆing

If value is your decimal value:

string code = $"U+{value.ToString ("X4")}";

will give you what you want.

(X means hex, 4 means pad to 4 digits)
