    C# bitwise operations.

    In the code
    Code:
    UInt64 mask = (UInt64)((message[4] << 48) | (message[5] << 40) | (message[6] << 32) | (message[7] << 24) |
                                      (message[8] << 16) | (message[9] << 8) | message[10]);
    
    for (UInt64 i = 0; i < 64; i++)
    {
        UInt64 c = mask & ((UInt64)(1) << i);
    }
    I get
    Error CS0019 Operator '<<' cannot be applied to operands of type 'ulong' and 'ulong'

    Should I split UInt64 for two UInt32 or is there any way around?

    Overkill much?
    You can count to 64 in a byte ffs.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
