How do I convert C# characters to their hexadecimal code representation

问题:

What I need to do is convert a C# character to an escaped unicode string:

So, 'A' - > "\x0041".

Is there a better way to do this than:

char ch = 'A'; string strOut = String.Format("\\x{0}", Convert.ToUInt16(ch).ToString("x4")); 

回答1:

Cast and use composite formatting:

char ch = 'A'; string strOut = String.Format(@"\x{0:x4}", (ushort)ch);
