SetBits(int, bool, int)

Sets a range of bits to 0 or 1.
public void SetBits(int pos, bool value, int numBits)

Parameters

pos

int
Index of the first bit to set.

value

bool
True for 1, false for 0.

numBits

int
Number of bits to set.

Remarks

The range runs from index 
pos
up to (but not including) 
pos + numBits
. No exception is thrown if 
pos + numBits
exceeds the length.

SetBits(int, ulong, int)

Copies bits of a ulong to bits in this array.
public void SetBits(int pos, ulong value, int numBits = 1)

Parameters

pos

int
Index of the first bit to set.

value

ulong
Unsigned long from which to copy bits.

numBits

int
Number of bits to set (must be between 1 and 64).

Remarks

The destination bits in this array run from index pos up to (but not including) 
pos + numBits
. No exception is thrown if 
pos + numBits
exceeds the length.
The lowest bit of the ulong is copied to the first destination bit; the second-lowest bit of the ulong is copied to the second destination bit; and so forth.
