| Description |
|
A new BitArray is created that has all of the Source elements, but inverted. 1 values become 0, 0 values become 1.
|
| | Notes | IMPORTANT : you must prefix the method name Not with an & to avoid a compiler error, where the method name is confused with the native Delphi operator.

| A simple example |
program Project1;
{$APPTYPE CONSOLE}
uses
System.Collections;
var
Source, Target : System.Collections.BitArray;
i : Integer;
begin
// Create our bit arrays
Source := System.Collections.BitArray.Create(4);
Target := System.Collections.BitArray.Create(4);
// Set the values in both arrays
Source[0] := false; // 0
Source[1] := false; // 0
Source[2] := true; // 1
Source[3] := true; // 1
for i := 0 to Source.Count-1 do
if Source[i]
then Console.WriteLine('Source [{0}] = 1', i.ToString)
else Console.WriteLine('Source [{0}] = 0', i.ToString);
// Perform a logical NOT of Source into Target :
Target := Source.⫬ // Note the &
Console.WriteLine;
for i := 0 to Target.Count-1 do
if Target[i]
then Console.WriteLine('Target [{0}] = 1', i.ToString)
else Console.WriteLine('Target [{0}] = 0', i.ToString);
Console.ReadLine;
end.
