Use   amp  amp   for AND and use      for OR  for example   bool A  bool B   bool resultOfAnd   A  amp  amp  B     Returns the result of an AND bool resultOfOr   A    B     Returns the result of an OR

I m not sure if this answers your question  but for example   if  A    B        Console WriteLine  Or       if  A  amp  amp  B        Console WriteLine  And

If what interests you is bitwise operations look here for a brief tutorial   http   weblogs asp net alessandro archive 2007 10 02 bitwise-operators-in-c-or-xor-and-amp-amp-not aspx  bitwise operation perform the same operations like the ones exemplified above they just work with binary representation  the operation applies to each individual bit of the value   If you want logical operation answers are already given

There is a distinction between the conditional operators  amp  amp  and    and the boolean operators  amp  and    Mainly it is a difference of precendence  which operators get evaluated first  and also the  amp  amp  and    are  escaping   This means that is a sequence such as     cond1  amp  amp  cond2  amp  amp  cond3   If cond1 is false  neither cond2 or cond3 are evaluated as the code rightly assumes that no matter what their value  the expression cannot be true  Likewise     cond1    cond2    cond3   If cond1 is true  neither cond2 or cond3 are evaluated as the expression must be true no matter what their value is   The bitwise counterparts   amp  and   are not escaping   Hope that helps

amp  amp  it s operation return true only if both operand it s true  which implies  bool and bool b1  bool b2      if b1  true        if b2  true      return true      return false         it s operation return true if one or both operand it s true which implies  bool or bool b1 bool b2     if b1  true   return true   if b2  true   return true   return false      if You write  y 45 amp  amp 34  45 binary 101101  35 binary 100010   in result you have   y 32   in binary 100000   Therefore  the which I wrote above is used with respect to every pair of bits

many answers above  i will try a different way   if you are looking for bitwise operations use only one of the marks like   3  amp  1     1 - and 4   1     5 - or

Logical OR is     logical AND is  amp  amp   If you need the negation NOT  prefix your expression with     Example   X    A  amp  amp  B     C     D    Then X will be true when either A and B are true or if C is true or if D is not true  i e  false    If you wanted bit-wise AND OR NOT  you would use  amp     and    But if you are dealing with boolean truth values  you do not want to use those  They do not provide short-circuit evaluation for example due to the way a bitwise operation works
