Property Value

Int32

The number of elements in the BitArray.

Exceptions

ArgumentOutOfRangeException

The property is set to a value that is less than zero.

Remarks

Length and Count return the same value. Length can be set to a specific value, but Count is read-only.

If Length is set to a value that is less than Count, the BitArray is truncated and the elements after the index value -1 are deleted.

If Length is set to a value that is greater than Count, the new elements are set to false.

Retrieving the value of this property is an O(1) operation. Setting this property is an O(n) operation.
