Remarks
In languages that detect overflow, OverflowException is the exception that gets thrown. For example, in C#, the checked keyword is used to detect overflow conditions. An OverflowException exception occurs only in a checked context.
The following Microsoft intermediate language ( MSIL ) instructions throw OverflowException:
- add.ovf.<signed>
- conv.ovf.<to type>
- mul.ovf.<type>
- sub.ovf.<type>
For a result from an integral or decimal-type arithmetic operation or conversion that is outside the range of the destination type:
- In a checked context, a compile-time error occurs if the operation is a constant expression. Otherwise, an OverflowException is thrown if the operation is performed at run-time.
- In an unchecked context, the result is truncated by discarding any high-order bits that do not fit in the destination type.
OverflowException uses the HRESULT COR_E_OVERFLOW, that has the value 0x80131516.
For a list of initial property values for an instance of OverflowException, see the OverflowException constructors.
