Remarks

The Action property contains the security action that caused the security check failure. Many of the security actions can cause a security exception to be thrown. For example, a demand on a permission set checks that all callers on the call stack have the necessary permissions in the permission set. If any caller on the call stack lacks a required permission, the security check fails. Alternatively, a method in the call chain can modify the outcome of the stack walk by placing a stack walk modifier, such as Deny or PermitOnly, on the stack to limit the allowed permissions. For example, a method on the call stack might deny all of its callers a set of permissions named PSET1, such that any demand for a permission that is part of PSET1 fails for those callers. The Action property contains the security action that caused the exception to be thrown.

SecurityAction is an enumeration in the SecurityAction namespace that provides the security action value for the Action property. Typically this property contains one of the values shown in the following table.

Security action	Description
Demand	A full stack walk failed due to a demand made against the assembly identified by the FailedAssemblyInfo property.
LinkDemand	A link demand against the assembly identified by the FailedAssemblyInfo property failed.
InheritanceDemand	An assembly identified by the FailedAssemblyInfo property failed to meet an inheritance demand.
PermitOnly	A demanded permission did not match any permission in the PermitOnly permission set. The method that placed the PermitOnly on the call stack is identified by the Method property.
Deny	A demanded permission matched a permission in the deny permission set on the call stack. The method that placed the Deny on the call stack is identified by the Method property.
