The System.Char datatype in the CLR is unicode. You can define your ascii
character variable as a byte and assign initialize it like so:

<codeSnippet language="C#">
byte asciiA = (byte)'A';
</codeSnippet>

The value of asciiA will be 65. Also, you can also convert characters and
strings to ASCII at runtime using
System.Encoding.ASCII.GetBytes/GetString().
