Convert.ToInt32(float) fails when trying to convert float to Int32

Question

No exception is thrown, function just halts at this statement:

int productQuantity = Convert.ToInt32(\"1.00\");

and returns.

What

Answer 1

An exception is being thrown in this case it's just not being surfaced in the debugger. This string is not in a format that is convertible to an Int32 type and hence throws and exception. You can verify this by wrapping it in a try/catch block if the IDE isn't cooperating.

The best approach here is probably to convert the string to a double and then manually cast it down to an int. This does open the door for data loss due to precision differences. But given your input is in a float style format this is unavoidable if you want the final product to be an int
