    Is it possible to use bitfields in C?
    Not exactly the same as BitFields While your code does help a bit, it's very far removed from the bitfields' usage in C. I wonder it something like [StructLayout(LayoutKind.Explicit)] and [FieldOffset(offset)] could help with that. At least in that case you can have byte fields actually change some other fields' values.

    What is bit field type?
    It is an integer type that determines the bit-field value which is to be interpreted. The type may be int, signed int, or unsigned int. The member name is the name of the bit field. The number of bits in the bit-field. The width must be less than or equal to the bit width of the specified type.

    What is bit-field in encryption?
    When devices transmit status or information encoded into multiple bits for this type of situation bit-field is most efficient. Encryption routines need to access the bits within a byte in that situation bit-field is quite useful. For example, consider the following declaration of date without the use of bit fields.

    How to mimic the functionality of bit field structure in C?
    The goal is to mimic the functionality of a bit field structure in C with an implementation in C#. This is done by writing some custom attributes that can be applied to the C# struct and also some extension methods used to convert to and from an integer value and also to convert the value to a string with the base-2 representation of the value.
