The BitArray class manages a compact array of bit values, which are represented as Booleans, where true indicates that the bit is on i.e, 1 and false indicates the bit is off i.e, 0. This class is contained in System.Collections namespace.
BitArray.And(BitArray) method is used to perform the bitwise AND operation between the elements of the current BitArray object and the corresponding elements in the specified array.
The current BitArray object will be modified to store the result of the bitwise AND operation.
- The BitArray class is a collection class in which the capacity is always the same as the count.
- Elements are added to a BitArray by increasing the Length property.
- Elements are deleted by decreasing the Length property.
- The BitArray class provides methods like And, Or, Xor, Not, and SetAll.
- Elements in this collection can be accessed using an integer index. Indexes in this collection are zero-based.
public System.Collections.BitArray And (System.Collections.BitArray value);
Here, value is the array with which to perform the bitwise AND operation.
Return Value: It returns an array containing the result of the bitwise AND operation, which is a reference to the current BitArray object.
- ArgumentNullException : If the value is null.
- ArgumentException : If the value and the current BitArray do not have the same number of elements.
Below given are some examples to understand the implementation in a better way:
False False False True
System.ArgumentException: Array lengths must be the same.
- The bitwise AND operation returns true if both operands are true, and returns false if one or both operands are false.
- This method is an O(n) operation, where n is Count.
