Access same string in different methods

[Radical]

If I have a situation like this:

protected override void OnStartUp()
{
string a = "pie";
}

protected override void OnBarUpdate()
{
Print(a);
} 

It seems that the string "a", which was declared in OnStartUp, produces an error ("The name 'a' does not exist in the current context") when referenced in OnBarUpdate. Is there a way to get around this? Thanks.

Radical, it must be declared outside the scope of the method:

string a
OnStartUp()
{
  a = "pie";
}
OnBarUpdate()
{
   Print(a);
}

Thanks, that worked.
