| Exception | Condition |
|---|---|
| NullReferenceException | The address of location1 is a null pointer. |
This method handles an overflow condition by wrapping: if the value at location1 is Int32::MaxValue and value is 1, the result is Int32::MinValue; if value is 2, the result is (Int32::MinValue + 1); and so on. No exception is thrown.
