[HostProtectionAttribute(SecurityAction.LinkDemand, SharedState = true)]
public class InvalidEnumArgumentException : ArgumentException

The InvalidEnumArgumentException type exposes the following members.

Public methodInvalidEnumArgumentException()Initializes a new instance of the InvalidEnumArgumentException class without a message.
Public methodInvalidEnumArgumentException(String)Initializes a new instance of the InvalidEnumArgumentException class with the specified message.
Protected methodInvalidEnumArgumentException(SerializationInfo, StreamingContext)Initializes a new instance of the InvalidEnumArgumentException class using the specified serialization data and context.
Public methodInvalidEnumArgumentException(String, Exception)Initializes a new instance of the InvalidEnumArgumentException class with the specified detailed description and the specified exception.
Public methodInvalidEnumArgumentException(String, Int32, Type)Initializes a new instance of the InvalidEnumArgumentException class with a message generated from the argument, the invalid value, and an enumeration class.

Public propertyDataGets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception.)
Public propertyHelpLinkGets or sets a link to the help file associated with this exception. (Inherited from Exception.)
Protected propertyHResultGets or sets HRESULT, a coded numerical value that is assigned to a specific exception. (Inherited from Exception.)
Public propertyInnerExceptionGets the Exception instance that caused the current exception. (Inherited from Exception.)
Public propertyMessageGets the error message and the parameter name, or only the error message if no parameter name is set. (Inherited from ArgumentException.)
Public propertyParamNameGets the name of the parameter that causes this exception. (Inherited from ArgumentException.)
Public propertySourceGets or sets the name of the application or the object that causes the error. (Inherited from Exception.)
Public propertyStackTraceGets a string representation of the immediate frames on the call stack. (Inherited from Exception.)
Public propertyTargetSiteGets the method that throws the current exception. (Inherited from Exception.)

Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetBaseExceptionWhen overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions. (Inherited from Exception.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetObjectDataSets the SerializationInfo object with the parameter name and additional exception information. (Inherited from ArgumentException.)
Public methodGetTypeGets the runtime type of the current instance. (Inherited from Exception.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringCreates and returns a string representation of the current exception. (Inherited from Exception.)

Protected eventSerializeObjectStateOccurs when an exception is serialized to create an exception state object that contains serialized data about the exception. (Inherited from Exception.)

This exception is thrown if you pass an invalid enumeration value to a method or when setting a property.


The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: SharedState. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.

The following code example shows how to catch an InvalidEnumArgumentException exception and interpret its content. The example attempts to pass an invalid enumeration value (MessageBoxButtons) through casting, as the MessageBox.Show method's third argument. Upon catching the exception, the example fetches the respective error message, the invalid parameter, stack trace, and origin of the exception.

		// Attempts to pass an invalid enum value (MessageBoxButtons) to the Show method
		    MessageBoxButtons myButton= (MessageBoxButtons) 123;
		    MessageBox.Show("This is a message","This is the Caption",myButton);
		catch(InvalidEnumArgumentException invE)
