HI all,
I am a newbie to C#....
I have a byte[] of variable length. Starting from byte[15] the array, i
have the following content in the array:

[username\0password\0info\01234]

How can I extract those string from the byte[]?

Hope someone can give me some advice.

Thanks.

There are several ways to accomplish this. U can use StringBuilder to append
bytes u read from the array.

Or you can convert byte array to a string.
System.Text.Encoding.Default.GetString method...

or too much solutions...
 
Hi,

you can use one of the XXXEncoding ( ASCIIEncoding , UTF8Encoding )
GetString method.


Cheers,
 
But since the string comes in at the 15 bytes of the array and end by a
\0...and the other string start right after the prior \0, how could i
effectively pass the content between those into a stringbuilder?
