You can use the Convert class or the Parse method of the built-in type you are casting to. i.e.
string myStr = “123”;
int myParsedInt = Int32.Parse(myStr);
int myConvertedInt = Convert.ToInt32(myStr);
This example uses the int type, but you can also use the same techniques for any of the other integral or floating point types.
