call system dll method csharp

call system dll method in csharp application.

in this example we are using User32.dll file.

What is difference between AND & and Logical AND &&?

1. Logical AND Sign is && and AND Sign is  &.

2. Both work is same but Operation Method is Different

for example

if(a==10 && b==10)

here if a =10 then only it going for  checking b value

if a !=10 then condition is not satisfied.

Moral One Operation for checking second values decrases

and in AND & operation

if(a==10 & b==10)

here if a !=10 then also it is checking B value it is not necessary.

Logical AND(&&) is Best.
