C# reading certain digits from binary data

[sbjv]

Hi ,
I have one python script which i am trying to convert and stuck in one place and unable to proceed. any help would be appreciated

Python script:----------------
import hashlib
meid = raw_input("Enter an MEID: ").upper()
s = hashlib.sha1(meid.decode('hex'))
#decode the hex MEID (convert it to binary!)
pesn = "80" + s.hexdigest()[-6:].upper()
#put the last 6 digits of the hash after 80
print "pESN: " + pesn
My C# conversion:*************************************** **

UInt64 EsnDec = 2161133276;
string EsnHex=string.Format("{0:x}", EsnDec);
string m = Convert.ToString(Convert.ToUInt32(EsnHex, 16), 2);
/*---------------------------------------------
Stuck here. Now m got complete binary data
and i need to take last 6 digits as per python
script and prefix "80".
---------------------------------------------*/
Console.WriteLine(m);
Console.Read();


Any help would be appreciated
