Remarks

Caution

Code Access Security (CAS) has been deprecated across all versions of .NET Framework and .NET. Recent versions of .NET do not honor CAS annotations and produce errors if CAS-related APIs are used. Developers should seek alternative means of accomplishing security tasks.

Note

The ResourcePermissionBase class compares strings using ordinal sort rules and ignores the case of the strings being compared.

Notes to Implementers

When you inherit from ResourcePermissionBase, you must provide at least three constructors, set two properties, and provide a third property. The required constructors are: a parameterless constructor, one that takes a PermissionState as a parameter, and as many as needed that take values for the properties. The properties that need to be set are PermissionAccessType and TagNames. The third property that is needed is one that returns the permission entries. For an example of an implementation of this class, see PerformanceCounterPermission. In PerformanceCounterPermission, the TagNames property is set privately to "Machine" and "Category", the PermissionAccessType property is privately set to the type of PerformanceCounterPermissionAccess, and the PermissionEntries property returns the permission entries.

Constructors

ResourcePermissionBase()	Initializes a new instance of the ResourcePermissionBase class.
ResourcePermissionBase(PermissionState)	Initializes a new instance of the ResourcePermissionBase class with the specified level of access to resources at creation.

Fields

Any	Specifies the character to be used to represent the any wildcard character.
Local	Specifies the character to be used to represent a local reference.

Properties

PermissionAccessType	Gets or sets an enumeration value that describes the types of access that you are giving the resource.
TagNames	Gets or sets an array of strings that identify the resource you are protecting.

Methods

AddPermissionAccess(ResourcePermissionBaseEntry)	Adds a permission entry to the permission.
Assert()	Declares 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)
Clear()	Clears the permission of the added permission entries.
Copy()	Creates and returns an identical copy of the current permission object.
Demand()	Forces 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)
Deny()	Obsolete. Obsolete. 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)
Equals(Object)	Determines whether the specified CodeAccessPermission object is equal to the current CodeAccessPermission. (Inherited from CodeAccessPermission)
FromXml(SecurityElement)	Reconstructs a security object with a specified state from an XML encoding.
GetHashCode()	Gets 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)
GetPermissionEntries()	Returns an array of the ResourcePermissionBaseEntry objects added to this permission.
GetType()	Gets the Type of the current instance. (Inherited from Object)
Intersect(IPermission)	Creates and returns a permission object that is the intersection of the current permission object and a target permission object.
IsSubsetOf(IPermission)	Determines whether the current permission object is a subset of the specified permission.
IsUnrestricted()	Gets a value indicating whether the permission is unrestricted.
MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
PermitOnly()	Prevents 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)
RemovePermissionAccess(ResourcePermissionBaseEntry)	Removes a permission entry from the permission.
ToString()	Creates and returns a string representation of the current permission object. (Inherited from CodeAccessPermission)
ToXml()	Creates and returns an XML encoding of the security object and its current state.
Union(IPermission)	Creates a permission object that combines the current permission object and the target permission object.
