Empty statement in C#

While studying for the C# certification test number 70-483 I was shocked that in C# it is possible to write an empty statement. Perhaps you might think that this is a simple non-important thing. ALLOW ME TO DISAGREE ... during a certification exam you might feel a little bit over confident with your knowledge and overlook the little and small details. So, if you look a question that includes the following code you might believe in a classical Akbarian way that this "It's a trap!"

// empty statement
void SomeFunction()
{
     while(DoSomething())
     ;
}

The semi-colon beneath the while body is an empty statement. It is a simple way of telling the compiler that nothing will happen there. It is a valid C# construct and IT WILL COMPILE. Don't be tricked!

The most common variation of the previous code is:

// empty statement
void SomeFunction()
{
     while(DoSomething())
     {
     }
}
