In C#/.NET type can be converted to byte in few ways.

1. Convert.ToByte example

int input = 123;
byte output = Convert.ToByte(input);
Console.WriteLine(output);

Output:

123
Note: Convert.ToByte prevents value overflowing (min value 0, max value 255).

2. Explicit conversion

int input = 1234;
byte output = (byte)input;
Console.WriteLine(output);

Output:

123
Note: This kind of conversion cuts most significant bits!
For conversion int 1234 to byte cutting behaves like in this example:
______________________________________________________      ___________
Bit index: 31        23        15        7       0    |    |           |
Bit value: 0000 0000 0000 0000 0000 0100 1101 0010 (2)| ‬=> | 1234 (10) |
Bit value:    ‭                           1101 0010‬ (2)| => | 210  (10) |
