Constructors

	Name	Description
	HostProtectionException()	Initializes a new instance of the HostProtectionException class with default values.
	HostProtectionException(SerializationInfo^, StreamingContext)	Initializes a new instance of the HostProtectionException class using the provided serialization information and streaming context.
	HostProtectionException(String^)	Initializes a new instance of the HostProtectionException class with a specified error message.
	HostProtectionException(String^, Exception^)	Initializes a new instance of the HostProtectionException class with a specified error message and a reference to the inner exception that is the cause of this exception.
	HostProtectionException(String^, HostProtectionResource, HostProtectionResource)	Initializes a new instance of the HostProtectionException class with a specified error message, the protected host resources, and the host resources that caused the exception to be thrown.

Methods

	Name	Description
	Equals(Object^)	Determines whether the specified object is equal to the current object.(Inherited from Object.)

	GetBaseException()	When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions.(Inherited from Exception.)
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetObjectData(SerializationInfo^, StreamingContext)	Sets the specified SerializationInfo object with information about the host protection exception.(Overrides Exception::GetObjectData(SerializationInfo^, StreamingContext).)
	GetType()	Gets the runtime type of the current instance.(Inherited from Exception.)
	MemberwiseClone()	Creates a shallow copy of the current Object.(Inherited from Object.)
	ToString()	Returns a string representation of the current host protection exception.(Overrides Exception::ToString().)

Events

	Name	Description
	SerializeObjectState	Occurs when an exception is serialized to create an exception state object that contains serialized data about the exception.(Inherited from Exception.)

A HostProtectionAttribute attribute is used to determine if a type or member can be loaded, based on the host’s protection preferences established when the common language runtime is started. If a type or member with an active HostProtectionAttribute is called, a link demand occurs for that protection attribute. If the caller does not meet the demand for host protection, a HostProtectionException is thrown.

Note
A HostProtectionAttribute is not a permission, even though it is the target of a link demand. Because a HostProtectionException is thrown for a link demand, it cannot be handled, and therefore it cannot be trapped and processed in code.
