Kind of a newbie question, but I need to be able to convert a string to
an integer in C#, similar to VB's Val(). Anybody know how to do this?
I've tried C-style casting (obviously to no avail).
 
int.Parse("42");

You have to think about "what would provide the functionality?" to know where to look as there are no global functions. So what would know what an int is meant to look like as a string? An int! :-)

Use int.Parse(string) or Convert.ToInt32(string). Various overloads
allow you some different options.
 
If you would like to determine whether the string can be parsed into an int,
take a look at the double.TryParse() method. Otherwise, if your string is
input by the user, you'll want to surround it with a try/catch block.
