Constructors
NameDescription
System_CAPS_pubmethod SecurityPermission

Initializes a new instance of the SecurityPermission class with either restricted or unrestricted permission as specified.

System_CAPS_pubmethod SecurityPermission

Initializes a new instance of the SecurityPermission class with the specified initial set state of the flags.

Properties
NameDescription
System_CAPS_pubproperty

Gets or sets the security permission flags.

Methods
NameDescription
System_CAPS_pubmethod 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.)

System_CAPS_pubmethod Copy

Creates and returns an identical copy of the current permission.(Overrides CodeAccessPermissionCopy.)

System_CAPS_pubmethod 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.)

System_CAPS_pubmethod Deny

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.)

System_CAPS_pubmethod Equals

Determines whether the specified CodeAccessPermission object is equal to the current CodeAccessPermission.(Inherited from CodeAccessPermission.)

System_CAPS_pubmethod FromXml

Reconstructs a permission with a specified state from an XML encoding.(Overrides CodeAccessPermissionFromXml.)

System_CAPS_pubmethod 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.)

System_CAPS_pubmethod GetType

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethod Intersect

Creates and returns a permission that is the intersection of the current permission and the specified permission.(Overrides CodeAccessPermissionIntersect.)

System_CAPS_pubmethod IsSubsetOf

Determines whether the current permission is a subset of the specified permission.(Overrides CodeAccessPermissionIsSubsetOf.)

System_CAPS_pubmethod IsUnrestricted

Returns a value indicating whether the current permission is unrestricted.

System_CAPS_pubmethod 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.)

System_CAPS_pubmethod ToString

Creates and returns a string representation of the current permission object.(Inherited from CodeAccessPermission.)

System_CAPS_pubmethod ToXml

Creates an XML encoding of the permission and its current state.(Overrides CodeAccessPermissionToXml.)

System_CAPS_pubmethod Union

Creates a permission that is the union of the current permission and the specified permission.(Overrides CodeAccessPermissionUnion.)

Remarks

This permission uses the SecurityPermissionFlag enumeration. The values for this enumeration can be found in its documentation.
