This comes up regularly from beginners and is nearly always a bad idea! The easy solution is to use a dictionary to store the instances.

A Dictionary is best. The problem is, once you create your new variables none of the rest of your code knows aout them so how can it access them. And what if someone enters a name that is being iused elsewhere in your code? You will overwrite a real variable with this new object! Very tricky to control.
