I need to convert the following code snippet into C#, how is this possible?

C++

char south=ais_binary[89];
    temp_s=ais_binary.substr(89,27);
    bitset<27> ii(temp_s);
    if (south=='1') {ii.flip();}
    double ais_latitude=ii.to_ulong();
    ais_latitude=ais_latitude/10000/60;
    if (south=='1') {ais_latitude *= -1;}

Thanks in advance

You need to have more specific questions, "do it for me" is not the right attitude.

First of all, the code is not so good even as C++:
1) use of all those immediate constants (89, 27, '1', etc.) makes the code very hard to maintain; 2) comparison with character '1' is bad way to represent pure logic, 3) some declarations are not shown: where is ais_binary (could be an instance of some class implementing indexing), temp_s?

The lack of some declarations makes literal translation uncertain, but you only need some ideas:

To represent bit set, use System.Collections.BitArray,
see http://msdn.microsoft.com/en-us/library/system.collections.bitarray.aspx[^].
To get a slice of some array use the static methods <copy>System.Array.Copy. See: http://msdn.microsoft.com/en-us/library/system.array.aspx[^],
http://msdn.microsoft.com/en-us/library/z50k9bft.aspx[^].
Everything else looks the same: if statement, block…

Probably that's it.
