check if string is base64 encoded

hey all
currently i use the following piece of code to check if the string passed to me can be converted to base64, it is not very efficient and bad, can someone please suggest another of doing this

private string ConvertBase64ToString(string[] content)
StringBuilder sb = new StringBuilder();
int i = content.GetUpperBound(0);
for (int j=0; j<i; j++)
// if successful in converting base64 append it.
catch (Exception)
// cannot be decoded so append the original string
return sb.ToString();

content passed to be looks like:
some string not containing base64
another strign without base64

some more strings without base64

is it possible to somehow find out if a line is base64 without attempting to covert it and catching the exception?

getting base64 encoded string using IdHttp
yes hello good to be back... so i have written a REST server in PHP to talk to my IdHttp client that base64 encodes a jpeg in order to send the data in a record "packet" of my own design. I then use a TStringList.delimitedText to read the received packet and parse the results into key/value pairs (kind of a homestyle JSON format). this is working well for all the other data, but it seems that the base64 field is being limited to 4096 bytes when i call the RawByteString thumb64 := tsServerReply.Values['base64field']; the original 'base64field' i...

NET::LDAP, somewhere the new userPassword gets base64 encoded
I'am using the Perl Net::LDAP Module with openldap-2.3.24 (uses LDAP protocol Version 3). I need to update the userPassword field, the problem is that somewhere in the middle the new password i'am giving gets base64 encoded. As to my understanding i'am preparing the whole password. In the password i'am putting first the encoding type: {MD5}, {SSHA}, etc and then the hash. No matter what i do, even the supposed encoding type gets base64 encoded once in the Server. I'am not sure if it is Net::LDAP or the server itself who is doing this: I've tried ...

To Encode String or to Not Encode String... Answer?
I am importing a CSV file from a Unix server as a string, and then saving the string into a new file for later processing.  However, this process does not always work.  As this CSV file is VERY, VERY large, I am unable to immediately tell if the fault lies with my code, or the CSV file provider (very possible).  The only time I can tell that this happened is when the data is not populated the next morning.  The fault appears to lie in there being extra or missing commas, as when I try to run the data import manually, STRINGs are attempted to be inserted into INT...
