The exception that is thrown when a denied host resource is detected.


Namespace:  System.Security
Assembly:  mscorlib (in mscorlib.dll)

<SerializableAttribute> _
<ComVisibleAttribute(True)> _
Public Class HostProtectionException _
	Inherits SystemException

The HostProtectionException type exposes the following members.

Public methodHostProtectionExceptionInitializes a new instance of the HostProtectionException class with default values.
Public methodHostProtectionException(String)Initializes a new instance of the HostProtectionException class with a specified error message.
Protected methodHostProtectionException(SerializationInfo, StreamingContext)Initializes a new instance of the HostProtectionException class using the provided serialization information and streaming context.
Public methodHostProtectionException(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.
Public methodHostProtectionException(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.

Public propertyDataGets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception.)
Public propertyDemandedResourcesGets or sets the demanded host protection resources that caused the exception to be thrown.
Public propertyHelpLinkGets or sets a link to the help file associated with this exception. (Inherited from Exception.)
Public 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 a message that describes the current exception. (Inherited from Exception.)
Public propertyProtectedResourcesGets or sets the host protection resources that are inaccessible to partially trusted code.
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 the default hash function. (Inherited from Object.)
Public methodGetObjectDataSets the specified SerializationInfo object with information about the host protection exception. (Overrides Exception.GetObjectData(SerializationInfo, StreamingContext).)
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 methodToStringReturns a string representation of the current host protection exception. (Overrides Exception.ToString.)

Protected eventSerializeObjectStateOccurs 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.


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.
