OverflowException: Value was either too large or too small for an Int32

Question: How do you solve for the error that says "OverflowException: Value was either too large or too small for an Int32" when trying to parse a string into an Int32.

Answer: This means that the string value you are trying to parse is over the limit of an Int32 since an Int32 can only store values between 2,147,483,647 and - 2,147,483,648. Which represents values that range from 0 to 4,294,967,295 The best solution is to use TryParse see the code below:

int.TryParse(myValue,out SomeInterger);

However, on the other side, if you used a UInt64 the values might have fitted because the UInt64 stores' values between 0, 18,446,744,073,709,551,615 but the memory allocation for this data type might exceed what is needed to store values in the memory slot. I guess it depends on your scenario, if Memory is not the issue here and are worried you might run into an Int32 Exceptions then go for UInt64.

The Memory Allocation for Integers is going to be allocated on the Stack, instead of on the Heap. This makes retrieving Integers faster than Strings. So the Speed/Time Complexity of retrieving an Integer vs a String is O(1), since there is no Boxing and UnBoxing of the value and the compiler stores the Pointer to the Memory Address holding the Integer value.
