C# XOR（它是如何为开发者工作的）

byte a = 0b10101010; // 170 in decimal
byte b = 0b11001100; // 204 in decimal
byte result = (byte)(a ^ b); // XOR operation
Console.WriteLine(Convert.ToString(result, 2)); // Output: 01100110

Dim a As Byte = &B10101010 ' 170 in decimal
Dim b As Byte = &B11001100 ' 204 in decimal
Dim result As Byte = CByte(a Xor b) ' XOR operation
Console.WriteLine(Convert.ToString(result, 2)) ' Output: 01100110

bool a = true;
bool b = false;
bool result = a ^ b; // Logical XOR operator
Console.WriteLine(result); // Output: True

Dim a As Boolean = True
Dim b As Boolean = False
Dim result As Boolean = a Xor b ' Logical XOR operator
Console.WriteLine(result) ' Output: True

int x = 5 ^ 2 + 3; 
Console.WriteLine(x); // Output: 0

CONVERTER NOT RUNNING

int x = 5 ^ (2 + 3); // Equivalent to 5 ^ 5

Dim x As Integer = 5 Xor (2 + 3) ' Equivalent to 5 ^ 5

5  = 00000101  
    5  = 00000101
