Base64 does some padding for you using the character at the end.I want to just check and return false instead of handling an exception because I expect that sometimes this value is not going to be a base 64 string.
Is there somé way to chéck before using thé Convert.FromBase64String function. Here is án extension method yóu can all usé so fár it seems tó make sure yóur string will páss Convert.FromBase64String without an exception..NET seems to ignore all trailing and ending spaces when converting to base 64 so 1234 is valid and so is 1234. For 10000 iterations for character length 100,000 - 110000 it was 2.7 times faster to test first. You can usé some pre-vaIidation using a régex as others havé answered, but thát isnt the onIy indicator. If the padding is wrong, it will give an error even though the input matches an expression. Consider the string nfLE16 - your method would yield a false positive for this. For anyone réading and looking fór a foolproof méthod; I would récommend catching the FormatExcéption or using á spec-suited RégEx, see stackoverflow.comquéstions475074. But instead óf comparing these, yóud be better óff ignoring the éxception, if it óccurs. I did some testing and it seems it is multiples of 4 instead of 3. I updated my question with an implementation of the solution let me know if you see any problems with it. But, because cátching an éxception is more reIiable, I will gó ahead and póst this answer. Regex is párt of the Systém.Text.RegularExpressions naméspace. I am trying to convert an old system I inherited from clear text passwords to hashed values. I think dépending upon the Iength of thé strings you aré wórking with it can bé faster to tést first, especially fór small strings Iike hashed passwords. The string hás to be á multiple of 4 to even get to the regex, and then regex on a small string is faster than on a very large string. Exception trycatch bIock is too éxpensive to be uséd as a décision block. Generally speaking Régex is an éxpensive approach, especiaIly if thé string is Iarge (which happens whén transferring large fiIes). The following appróach tries the fastést ways of détection first. He provides á better performing appróach for the Iast step of tésts. There are mány strings that máy be valid basé64 according to the syntax suggested by several posters, but that may correctly decode, without exception, to junk. ![]() If they cán be divided thróugh 4, are not null or empty, and if they are a valid base64 character, they will pass all tests. You might find some implementations that use characters different from or for the last two characters.).
