Efficiently Generating All Possible Integer List Combinations in C#

Generating all possible combinations from a C# integer list can be challenging, particularly when the list's size is variable. This approach uses bit manipulation and recursion for an efficient solution.

The core function, GetCombination, accepts an integer list as input. It calculates the total number of combinations (2 raised to the power of the list's count) and iterates through each combination using a bitwise representation.

Each iteration converts the binary representation of the iteration index into a string. The string is then parsed: if a character is '1', the corresponding list element is included in the current combination. These combinations are then output.

This method offers a robust and efficient way to generate all combinations, regardless of list size, optimizing performance through bitwise operations and handling dynamic list lengths effectively.
