BitArray Class:-
BitArray Class:-
  • The BitArray class manages a compact array of bit values, which are represented as Booleans, where true indicates that the bit is on (1) and false indicates the bit is off (0).
  • It is used when you need to store the bits but do not know the number of bits in advance.
  • You can access items from the BitArray collection by using an integer index, which starts from zero.

 


Methods and Properties of the BitArray Class:-

Methods of the BitArray Class:-

Sr.No. Methods
1 public BitArray And(BitArray value);

Performs the bitwise AND operation on the elements in the current BitArray against the corresponding elements in the specified BitArray.
2 public bool Get(int index);

Gets the value of the bit at a specific position in the BitArray.
3 public BitArray Not();

Inverts all the bit values in the current BitArray, so that elements set to true are changed to false, and elements set to false are changed to true.
4 public BitArray Or(BitArray value);

Performs the bitwise OR operation on the elements in the current BitArray against the corresponding elements in the specified BitArray.
5 public void Set(int index, bool value);

Sets the bit at a specific position in the BitArray to the specified value.
6 public void SetAll(bool value);

Sets all bits in the BitArray to the specified value.
7 public BitArray Xor(BitArray value);

Performs the bitwise eXclusive OR operation on the elements in the current BitArray against the corresponding elements in the specified BitArray.


Properties of the BitArray Class:-

Property Description
Count Gets the number of elements contained in the BitArray.
IsReadOnly Gets a value indicating whether the BitArray is read-only.
Item Gets or sets the value of the bit at a specific position in the BitArray.
Length Gets or sets the number of elements in the BitArray.
