Question

Confusion in a really a basic question:
I have seen in many books, they use use Console.WriteLine as:

int i = 12;
Console.WriteLine("MyVariable value is {0}", i);

Instead of

int i = 12;
Console.WriteLine("MyVariable value is" + i);

Is there any difference between them?

Answer 1

in your example, practically not. However, the first case can easily be extended to do

Console.WriteLine("MyVariable value is {0} and myothervar is {1}", i, j);

which could be a little cumbersom with the second approach.
