ASCII values

[Drew]

I need to display the ASCII numeric values of each letter in a string.

I think strings are stored in unicode in C# (?)

I can convert the string to a char array but how do I get the ascii values
of each character?

Thanks,

Drew

Oh, it looks like I can just cast the char to an int.

Is that the best way to do this?

Convert.ToInt32();

Yes, that's fine. Bear in mind that that will give you the Unicode
value, which will be the same as the ASCII value for all ASCII
characters. If you want to check whether or not it was actually an
ASCII character to start with, just check whether or not the value is
< 128.

Convert.ToInt32();

Why call a method when a simple cast (which could even be implicit)
works fine?

Sure, just remember that many chars are not ASCII. So if you happen to get
any data above 127, then it's not ASCII.

The implicit cast works great.

I didn't know it was that easy.
