real newbie question on c#

[Raymond Du]

Hi,

//The following c# code:
for (int i = 0; i<args.Length;i++)
{
int var1 = SomeFunction();
if (args > var1)
break;
}
//Question: will i and var1 still be available outside the for loop, say
from here?

Thanks in Advance

No, as I understand it. They are declared (created) in the for loop and
that is their scope.

No they will not be available outside the for loop. You would need to
create the variables outside the loop

int var = 0;
int i = 0;

for(i = 0; i<args.Length;i++))
{
var1 = SomeFunction();
if (args > var1)
break;
}

do something with var or i blah blah
