The exception that is thrown for invalid casting or explicit conversion.

InvalidCastException is thrown if:

• For a conversion from a Single or a Double to a Decimal, the source value is infinity, Not-a-Number ( NaN ), or too large to be represented as the destination type.
• A failure occurs during an explicit reference conversion.

For an explicit reference conversion to be successful, the source value must be a null reference ( Nothing in Visual Basic ), or that the object type referenced by the source argument is convertible to the destination type by an implicit reference conversion.

InvalidCastException uses the HRESULT COR_E_INVALIDCAST, which has the value 0x80004002.

For a list of initial property values for an instance of InvalidCastException, see the InvalidCastException constructors.
