In a recent discussion these code snippets were developed to replace Convert.ToInt32 and Convert.ToDouble. The person I was helping had a very large number of conversions to do. In our tests, using these 2 routines we were able to do over 1 million conversions in less than half the time. I thought it would be nice to share these with others. I found them quite useful as a class library.
Caveats: There is no validation or exception trapping. I figured that each person using these can decide on their own if they need it.
