difference between Convert & Int32

[luigi40]

reading a value in with Console.ReadLine i noticed there are two different methods i can use from the FCL

n=Convert.ToInt32(Console.ReadLine());

n=Int32.Parse(Console.ReadLine());

is there any difference in the value n ? (ie the range)

or are they 2 methods that do the same thing?

I believe they are different, as Int32.Parse can convert "1,000" to 1000, while I don't believe Convert.ToInt32 does. If it does, it would call Int32.Parse anyway, so it will be a little bit slower, so I'd call Int32.Parse myself.

Convert.ToInt32(string) and Int32.Parse(string) are two different methods that you can use to accomplish the same thing. The Convert method is there for completeness (you can convert from just about every other data type too), and the Parse method has overloads that are useful if you need to specify an IFormatProvider (which you probably don't if you're not worrying about internationalization) or a NumberStyles enumeration. The NumberStyles enumeration is pretty handy; it lets you decide what extra characters are allowed inside the number. For instance, you might want to allow a currency symbol, but you might want to disallow exponents.

In general, I'd use Int32.Parse. It allows more flexibility than Convert.ToInt32.
