Initializes a new instance of the BitArray class that contains bit values copied from the specified array of bytes.

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

public BitArray(
	byte[] bytes
)

Parameters

bytes
Type: System.Byte[]

An array of bytes containing the values to copy, where each byte represents eight consecutive bits.

ExceptionCondition
ArgumentNullException

bytes is null.

ArgumentException

The length of bytes is greater than MaxValue.

The first byte in the array represents bits 0 through 7, the second byte represents bits 8 through 15, and so on. The Least Significant Bit of each byte represents the lowest index value: " bytes [0] & 1" represents bit 0, " bytes [0] & 2" represents bit 1, " bytes [0] & 4" represents bit 2, and so on.

This constructor is an O(n) operation, where n is the number of elements in bytes.
