Invalid Length for Base-64 string problem

[Guest]

I have list of name separated by comm like this
name1,name2,name3,...etc
i converted then to Base-64 using Convert.ToBase64String() then pass them to
webmethod then i when try to get data back to original using
Convert.FromBase64String a crash generated with following error:

Invalid Lenght for Base-64 char array

what is the reason? the problem sometime code work and sometime it is crashed?
Is this a bug or what???

It sounds like it's probably a bug in your code. If it's not, you
should be able to produce a string x such that

Convert.FromBase64String(Convert.ToBase64String(x));

throws an exception. I'm sure if you can find such a string, MS would
be very keen on hearing about it.

actually the string is a URL containg query strings such

http://www.domain.com/Page.aspx?status=2&id=4

Well, you can convert that to and from base 64 with no problems, so it
must be something else going wrong.

Are you by any chance putting the base64-encoded string on a URL
afterwards? Base64 isn't "websafe" from what I remember.

Oh, and I meant to say - how are you converting the strings to a byte
array to start with?

Could you post a short but complete program which demonstrates the
problem?

what I mean by that.
