The SecurityPermission type exposes the following members.

Constructors
  NameDescription
Public method SecurityPermission(PermissionState)Initializes a new instance of the SecurityPermission class with either restricted or unrestricted permission as specified.
Public method SecurityPermission(SecurityPermissionFlag)Initializes a new instance of the SecurityPermission class with the specified initial set state of the flags.
Top
Properties
  NameDescription
Public property FlagsGets or sets the security permission flags.
Top
Methods
  NameDescription
Public method AssertDeclares that the calling code can access the resource protected by a permission demand through the code that calls this method, even if callers higher in the stack have not been granted permission to access the resource. Using Assert can create security issues. (Inherited from CodeAccessPermission.)
Public method CopyCreates and returns an identical copy of the current permission. (Overrides CodeAccessPermissionCopy.)
Public method DemandForces a SecurityException at run time if all callers higher in the call stack have not been granted the permission specified by the current instance. (Inherited from CodeAccessPermission.)
Public method DenyObsolete. Prevents callers higher in the call stack from using the code that calls this method to access the resource specified by the current instance. (Inherited from CodeAccessPermission.)
Public method EqualsDetermines whether the specified CodeAccessPermission object is equal to the current CodeAccessPermission. (Inherited from CodeAccessPermission.)
Public method FromXmlReconstructs a permission with a specified state from an XML encoding. (Overrides CodeAccessPermissionFromXml(SecurityElement).)
Public method GetHashCodeGets a hash code for the CodeAccessPermission object that is suitable for use in hashing algorithms and data structures such as a hash table. (Inherited from CodeAccessPermission.)
Public method GetTypeGets the Type of the current instance. (Inherited from Object.)
Public method IntersectCreates and returns a permission that is the intersection of the current permission and the specified permission. (Overrides CodeAccessPermissionIntersect(IPermission).)
Public method IsSubsetOfDetermines whether the current permission is a subset of the specified permission. (Overrides CodeAccessPermissionIsSubsetOf(IPermission).)
Public method IsUnrestrictedReturns a value indicating whether the current permission is unrestricted.
Public method PermitOnlyPrevents callers higher in the call stack from using the code that calls this method to access all resources except for the resource specified by the current instance. (Inherited from CodeAccessPermission.)
Public method ToStringCreates and returns a string representation of the current permission object. (Inherited from CodeAccessPermission.)
Public method ToXmlCreates an XML encoding of the permission and its current state. (Overrides CodeAccessPermissionToXml.)
Public method UnionCreates a permission that is the union of the current permission and the specified permission. (Overrides CodeAccessPermissionUnion(IPermission).)
