Use validation on critical user inputs to prevent zero values.

Set guards on functions that throw errors in the event of a zero value.

Use Try/Catch blocks to catch the exception.

Ways to fix/prevent DivideByZeroException:

To handle it gracefully, protect any code that does arithmetic division within try-catch blocks that look for that specific exception. The DivideByZeroException error gets thrown whenever a program tries to divide by zero.

See examples for avoiding the NullReferenceException.

Use Debug.Assert to catch the problem before the exception occurs.

Build null checking into the code and set default values.

The second line above will throw a NullReferenceException because we can’t call the method on a string that points to null. In the very simple example below, the string “foo” is set to null. NET exception gets thrown whenever we try to use a class reference that’s set to null/Nothing, when the code expects otherwise. ("C:\Program Files\Internet Explorer\IEXPLORE.This.
