What are the two keywords used to pass a variable by reference in c#?..

Answer / pramod singh

A variable of a reference type does not contain its data
directly; it contains a reference to its data. When you pass
a reference-type parameter by value, it is possible to
change the data pointed to by the reference, such as the
value of a class member. You cannot change the value of the
reference itself; that is, you cannot use the same reference
to allocate memory for a new class and have it persist
outside the block. To do that, pass the parameter using the
ref (or out) keyword. For simplicity, the following examples
use ref.
