Convert from string ascii to string Hex

Question

Suppose I have this string

string str = \"1234\"

I need a function that convert this string to this string:

\"0x31 0x32 0x33          


        

Answer 1

A nice declarative way to solve this would be:

var str = "1234"

string.Join(" ", str.Select(c => $"0x{(int)c:X}"))

// Outputs "0x31 0x32 0x33 0x34"
