The InvalidCastException type exposes the following members.
Constructors
Name | Description | |
---|---|---|
InvalidCastException() () () () | Initializes a new instance of the InvalidCastException class. | |
InvalidCastException(String) | Initializes a new instance of the InvalidCastException class with a specified error message. | |
InvalidCastException(String, Exception) | Initializes a new instance of the InvalidCastException class with a specified error message and a reference to the inner exception that is the cause of this exception. |

---|---|---|
Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) | |
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) | |
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) | |
GetType | Gets the Type of the current instance. (Inherited from Object.) | |
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) | |

Remarks
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 null Nothing nullptr unit a null reference (Nothing in Visual Basic) , or the object type referenced by the source argument must be convertible to the destination type by an implicit reference conversion.
Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
