Short-circuit evaluation in C# is a programming concept where the compiler skips the evaluation of some sub-expressions in a logical expression as soon as the value of the expression is determined[1][2][3]. This happens when using the logical AND (&&) and OR (||) operators.
Here's how it works:
For the && operator, if the first operand evaluates to false, the second operand is not evaluated because the entire expression will be false regardless of the second operand's value[1][2][3].
For the || operator, if the first operand evaluates to true, the second operand is not evaluated because the entire expression will be true regardless of the second operand's value[1][2][3].
In contrast, the bitwise AND (&) and OR (|) operators always evaluate both operands, even if the result can be determined from the first operand alone[3].
Short-circuit evaluation can be useful in several scenarios[1][2][3]:
Avoiding unexpected behavior or runtime errors: If an expression could cause an error (e.g., dividing by zero) in the second operand, ...
