	Name	Description
	AuthenticateUserToModify	Permission assignment that allows anonymous users to view and authenticated users to view and modify.
	Comparer	Gets the generic equality comparer that is used to determine equality of keys in the collection. (Inherited from System.Collections.ObjectModel.KeyedCollection<TKey,TItem>)
	Count	Gets the number of elements actually contained in the Collection. (Inherited from System.Collections.ObjectModel.Collection<TItem>)
	Empty	An empty permission assignment with no role permissions.
	EveryoneFullAccess	Permission assignment that gives full access to everyone (anonymous users).
	Item	Overloaded. Gets the element with the specified key. (Inherited from System.Collections.ObjectModel.KeyedCollection<TKey,TItem>)
	RoleBasis	Permission assignment based on the standard OPC UA roles with their base permissions.
	TrustApplicationToModify	Permission assignment that allows anonymous users to view and trusted applications to view and modify.

	Name	Description
	Dictionary	Gets the lookup dictionary of the KeyedCollection. (Inherited from System.Collections.ObjectModel.KeyedCollection<TKey,TItem>)
	Items	Gets a IList wrapper around the Collection. (Inherited from System.Collections.ObjectModel.Collection<TItem>)

	Name	Description
	Add	Overloaded. Adds a role with the specified permissions to the permission assignment.
	Clear	Removes all elements from the Collection. (Inherited from System.Collections.ObjectModel.Collection<TItem>)
	Clone	Overridden.
	Contains	Overloaded. Determines whether an element is in the Collection. (Inherited from System.Collections.ObjectModel.KeyedCollection<TKey,TItem>)
	CopyTo	Copies the entire Collection to a compatible one-dimensional System.Array, starting at the specified index of the target array. (Inherited from System.Collections.ObjectModel.Collection<TItem>)
	Equals	Overloaded. Overridden. Determines whether the current object is the same as other object.
	FilteredBy	Overloaded. Returns a filtered permission assignment containing only roles that the security principal has.
	FindPermissions	Finds the permissions assigned to the specified role.
	GetEnumerator	Returns an enumerator that iterates through the Collection. (Inherited from System.Collections.ObjectModel.Collection<TItem>)
	GetHashCode	Overridden.
	GetPermissionRoleIds	Gets Ids of roles that provide the specified permissions.
	GetPermissions	Overloaded. Gets the combined permissions for all roles that the security principal has.
	GetType	Gets the System.Type of the current instance. (Inherited from object)
	IndexOf	Searches for the specified object and returns the zero-based index of the first occurrence within the entire Collection. (Inherited from System.Collections.ObjectModel.Collection<TItem>)
	Insert	Inserts an element into the Collection at the specified index. (Inherited from System.Collections.ObjectModel.Collection<TItem>)
	IntersectWith	Intersects this permission assignment with another, keeping only the roles that are common between the two assignments. For each common role, the permissions are combined using a bitwise AND operation, ensuring that only permissions present in both assignments are retained. This operation modifies the current permission assignment in place.
	Remove	Overloaded. Removes the first occurrence of a specific object from the Collection. (Inherited from System.Collections.ObjectModel.KeyedCollection<TKey,TItem>)
	RemoveAt	Removes the element at the specified index of the Collection. (Inherited from System.Collections.ObjectModel.Collection<TItem>)
	RemoveEmptyPermissions	Removes all role permissions that have no permissions set (i.e., permissions equal to OpcLabs.EasyOpc.UA.UAPermissions.None).
	ToString	Overridden.
	UnionWith	Combines this permission assignment with another, combining permissions for common roles with a bitwise OR operation.

	Name	Description
	ChangeItemKey	Changes the key associated with the specified element in the lookup dictionary. (Inherited from System.Collections.ObjectModel.KeyedCollection<TKey,TItem>)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from object)
	MemberwiseClone	Creates a shallow copy of the current System.Object. (Inherited from object)

Equality	Determines whether the two objects are equal.
Inequality	Determines whether the two objects are not equal.
