So better choose the following UTF8:

String baseS = System.Convert.ToBase64String(System.Text.ASCIIEncoding.UTF8.GetBytes(“Glück”));
String back = System.Text.ASCIIEncoding.UTF8.GetString(System.Convert.FromBase64String(baseS));

I require an expert on this area to unravel my problem. Maybe that is you! Having a look ahead to look you.

Arcane – It’s still a great post. Thanks

im on my android…
by the way, the final program compiled can have the same size with or without uses, but the size of the file with the code will change…
but you all may be right:
we usually use 4kb as the default size of atribution unit…
so, those codes will result in 4kb of space on disk…
am i wrong???

Using Convert;
Using UTF8Encoding.Unicode;

Are internal clases and functions of “System.Text” and “System”, By this, it cannot be declared from “using”, what means that the code will not work.

At the final, if you debug the software, you can see that the program do the same callings to the .NET Classes, so… wherever you put the class names, the code will do the same thing, with the same size.

Don’t matter if have or not more chars, the callings will be the same, and that is what really matter when the program is compiled.

acording to http://www.charcounter.com/ the version with useless uses have 187 chars…
this was the “given” text:
Using Convert;
Using UTF8Encoding.Unicode;
private static string EDCode(string Text, bool Encode)
{
return (Encode) ? ToBase64String(GetBytes(Text)) : GetString(FromBase64String(Text));
}

without those uses, the size is 202 chars…
the text used was this:
private static string EDCode(string Text, bool Encode)
{
return (Encode) ? Convert.ToBase64String(UTF8Encoding.Unicode.GetBytes(Text)) : UTF8Encoding.Unicode.GetString(Convert.FromBase64String(Text));
}

so, is less size is not compression, what is compression then???

check by yourself…
but there is one thing that i agree with you: “same shit, diferent smell”
“same work, less space”

Dude, no offense, but… the fact of add “uses” don’t make it more compressed.

However, it is a valid code, but with unnecessarily “uses” added.

under “Using System;”, add this:
Using Convert;
Using UTF8Encoding.Unicode;
(…)

the function will look like this:

(…)
private static string EDCode(string Text, bool Encode)
{
return (Encode) ? ToBase64String(GetBytes(Text)) : GetString(FromBase64String(Text));
}
(…)

i hope it works…

private static string EDCode(string Text, bool Encode)
{
return (Encode) ? Convert.ToBase64String(UTF8Encoding.Unicode.GetBytes(Text)) : UTF8Encoding.Unicode.GetString(Convert.FromBase64String(Text));
}

Here’s a very compressed snippet:

public static string EDCode(string Text, bool Encode)
{
return (Encode) ? Convert.ToBase64String(ASCIIEncoding.UTF8.GetBytes(Text)) : ASCIIEncoding.UTF8.GetString(Convert.FromBase64String(Text)); //It returns the string deciphered or ciphered, depending on the value of variable “X.”
}

Regards.

{
return System.Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes(text));
}

this is the shortest way to encode…
it’s the same but WAY much small and WAY much optimized…
question: why optimized???
answer: because i’m saving 2 huge vars (one array of strings and one string) and there is only one step with 5 instructions… the original has 3 steps with 7 instructions…

private string decode(string text)
{
return System.Text.ASCIIEncoding.ASCII.GetString(System.Convert.FromBase64String(text));
}

this is how looks like the “compressed” function…

jeet, base64 is not for compressing but for encoding…
base64 increases the string size by 50%…
(or something like that)…
if i where you, i would firstlly encode, then compress…
zip compression is based in dictionary, so, as many times a “group” of bytes is repeated, the smaller the size…
try it…

UTF-8 is not a magic trick to cover for “non-ASCII stuff”; there are other ASCII-compatible encodings out there, and if the _reader_ expects one of those, the “non-ASCII stuff” will appear as random characters.

thank you for the post,
well I have different sort of scenario.

I have one big string on which I apply compression. then I apply Base64encoding, but sadly it increases size of the string ( compression :( ), what should I do? I use Zlib for the compression.

pleas suggest
jeet

P.S. do you have idea about iphone programming?

I like code examples that don’t throw in tons of extra stuff like error checking and whatnot. Any savvy developer will know to add this in to their own implementation where needed. Thanks!
