CodeGroup Class

Represents a node in a code group. A code group is a collection of security permissions for code that originates from a specific source.

Syntax

public abstract class CodeGroup : ISecurityEncodable, ISecurityIdentity, IPermission, SecurityElement.IElementCreator

Remarks

Code groups are the building blocks of the .NET Framework code access security (CAS) policy. Each code group is associated with a security grant, which is a set of permissions applied to code that matches the criteria of the code group.

The CodeGroup class is an abstract base class that defines the common properties and methods for all code groups. You typically do not instantiate CodeGroup directly, but rather use one of its derived classes to represent specific types of code groups.

The .NET Framework uses a hierarchical structure of code groups to determine the security permissions granted to an assembly. When an assembly is loaded, the runtime traverses this hierarchy, evaluating each code group to see if the assembly's origin matches the group's membership condition. If it matches, the permissions associated with that code group are granted to the assembly.
