Bitwise XOR. In VB.NET the keywords XOr, Or and And perform bitwise manipulations. When we use these operators on 2 Integers, a third Integer is returned.
These operators are the same as the punctuation-based operators in C-like languages. But in the VB.NET language, we use more descriptive keywords.
Example. This program uses 3 bitwise operators, the XOr, Or and And operators. It uses these operators and calls a function GetIntBinaryString to display the bits in an Integer.
Part 1 We use the XOr operator. The resulting Integer has a 1 in each place where either number has a 1, but not both.
Part 2 With Or, either number must have a 1 or both numbers can have a 1. If both numbers have a 0, the result is 0.
Part 3 With And, both numbers must have a 1 for the result to be 1. Otherwise the result is 0.

' Part 1: use XOR with 2 integers.
Dim a0 = 100
Dim b0 = 33
Dim result0 = a0 XOr b0
Console.WriteLine($"XOr: {GetIntBinaryString(a0)}")
Console.WriteLine($"XOr: {GetIntBinaryString(b0)}")
Console.WriteLine($"XOr: {GetIntBinaryString(result0)}")
' Part 2: use OR with 2 integers.
Dim a1 = 77
Dim b1 = 100
Dim result1 = a1 Or b1
Console.WriteLine($" Or: {GetIntBinaryString(a1)}")
Console.WriteLine($" Or: {GetIntBinaryString(b1)}")
Console.WriteLine($" Or: {GetIntBinaryString(result1)}")
' Part 3: use AND with 2 integers.
Dim a2 = 555
Dim b2 = 7777
Dim result2 = a2 And b2
Console.WriteLine($"And: {GetIntBinaryString(a2)}")
Console.WriteLine($"And: {GetIntBinaryString(b2)}")
Console.WriteLine($"And: {GetIntBinaryString(result2)}")

With VB.NET, we have access to all the bitwise operators found in other languages, but we must specify them in a different way. We use keywords like XOr, Or and And for bitwise manipulation.
