How can you check whether a string is convertible to an int?
Let's say we have data like "House", "50", "Dog", "45.99", I want to know whether I should just use the string or use the parsed int value instead.
In JavaScript we had this parseInt() function. If the string couldn't be parsed, it would get back NaN.
Int32.TryParse(String, Int32) - http://msdn.microsoft.com/en-us/library/f02979c7.aspx
bool result = Int32.TryParse(value, out number);
if (result)
{
Console.WriteLine("Converted '{0}' to {1}.", value, number);
}
Could you not make it a little more elegant by running the tryparse right into the if?
Like so:
if (Int32.TryParse(value, out number))
Console.WriteLine("Converted '{0}' to {1}.", value, number);
