Convert.FromBase64String dotnet bug?

[GeezerButler]

string s = "Hello";
byte[] abc = Convert.FromBase64String(s);

This throws error
"Invalid length for a Base-64 char array."??

Does anybody have any idea about how/why this happens?

Becase s is not a base64-encoded string.

Try Convert.ToBase64... instead.

Put cursor in FromBase64String. Hit F1. Help page says:
Exceptions

FormatException
The length of s, ignoring white space characters, is not zero or a
multiple of 4.
What are you actually trying to do?

Yes - it's like saving a file with the word "Hello" in and then opening
it up in Paintshop Pro as if it were a JPEG: "Hello" is not a valid
Base64-encoded lump of data.
