IPAddress creation

[MG]

Hello,

I try to create IPAddress object from array of bytes and it always throws
exception,
even when array of bytes is taken from proper IPAddress object:

IPAddress lAddress=IPAddr ess.Parse("1.2. 3.4");
byte[] lBytes=lAddress .GetAddressByte s();
IPAddress lNewAddress=new IPAddress(lByte s);

Has anyone encountered the problem?
Am I doing something wrong ??
(Im usingFramework 1.1)

MG,

What is the exception that is thrown? Also, what are the contents of
the byte array that you are passing in? You should have a 16-element byte
array. The reason for this is to account for the fact that IP addresses are
being widened at some point in time.

Hope this helps.

Re: IPAddress creation

Nicholas,

Thanks for help - passing array with 16 elements works.
Is there any info about this topic - I looked at online MSDN at

http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemnetipaddressclassctortopic1.asp

but found no info on format of the passed array.

Thought that GetAddressBytes () method returns data that is sufficient to
create another object.
I will work it out with my own conversion.

Thanks.
