Which is faster if-else or ? :

Which is faster in c# either

int a = 10;
bool _IsEven;
if(a%2 == 0)
{
   _IsEven = true;
}
else
{
   _IsEven = false;
}

Or

int a = 10;
bool _IsEven = a%2 == 0 ? true : false;

UPDATE

I know here I can optimize my code just writing

bool _IsEven = a%2 == 0;

But my question is not about code optimization rather it is regarding about performance of these two statements???

Can you please help me to improve my coding knowledge?
