Input string was not in a correct format #2

Question

double temp;
temp = (double)Convert.ToDouble(\"1234.5678\");

Hey Lads and Ladies, I can\'t for the life of me figure out why the above line isn\'t

Answer 1

first solution (as mentioned in other posts):

double temp = double.Parse("1234.5678", CultureInfo.InvariantCulture);

second solution - make it default to current thread:

Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;
double temp = double.Parse("1234.5678");

third solution - make it default to block of code:

var prevCurrentCulture = Thread.CurrentThread.CurrentCulture;
Thread.CurrentThread.CurrentCulture = CultureInfo.InvariantCulture;
...
double temp = double.Parse("1234.5678");
...
Thread.CurrentThread.CurrentCulture = prevCurrentCulture;
