ASP.Net Example

1. Logical OR 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 condition is Satisfied and not going checking values of B. 

Moral One Operation for checking second i.e B values decrasesand in AND & operation 

if(a==10 | b==10)

here if a ==10 then also it is checking B value i.e  it is not necessary.    
    
Logical OR(||) is Best.
