difference

[vinnie]

If i write:

double alfa = 10;

Console.WriteLine("The number is {0}", alfa");

it shows on the console: The number is 10.

Now, what the meaning if i write:
Console.WriteLine("The number is {0:xx}", alfa") ?

I know it's incorrect, i just can't figure out what does the colon and
the parameter xx may mean.

Thanks

Hi,

Both lines will giv eyou error, there is an extra " at the end.

Take a look at formatting in MSDN. It can get tricky at the beginning and
the best way to get it is seeing examples.

The string that comes after the colon is a formatting string. You can
for example use {0:N2}, which would format the number with two decimal
places.
