BitArray.Length Property

Gets or sets the number of elements in the BitArray.

Namespace:  System.Collections
Assembly:  mscorlib (in mscorlib.dll)

public int Length { get; set; }

Property Value

Type: System.Int32
The number of elements in the BitArray.

ExceptionCondition
ArgumentOutOfRangeException

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

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.
