Question

difference between & and && in .Net?

Jignesh Trivedi · Answer

hi && is also called short-circuiting logical operators. && is used to perform AND operation.it is generally used with IF condition. In this case of && if the first operand condition is false then it doesn't bother evaluating the second operand condition. & is called bitwise logical operation. in this case both Conditions are always execute. hope this will help you.

There's an important difference between the & operator when used with bool operands and the && operator namely that: 1. In the case of the & operator both operands are always evaluated. 2. In the case of the && operator the second operand is only evaluated if the first operand evaluates to 'true'. For this reason && is known as a 'short-circuiting' operator because it avoids a potentially unnecessary step and is nearly always preferred in practice. However on rare occasions evaluating the second operand may have a side effect which will not take place if the first operand is false. This can occur if the second operand involves a method call or property access. So if you're relying on this side effect you should use & rather than && though such programming is generally regarded as poor practice in a high level language such as C#.

Hello myat mon & is a bitwise operator where as && is a logical operator. Bitwise operators can operate on both -Integer & Boolean arguments where as Logical operators can operate only on Boolean arguments. Hope you got the point. Mark it as answer if it helps. Cheers!
