Allows security actions for ZoneIdentityPermission to be applied to code using declarative security. This class cannot be inherited.
Assembly: mscorlib (in mscorlib.dll)
[SerializableAttribute] [AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Constructor|AttributeTargets.Method, AllowMultiple = true, Inherited = false)] [ComVisibleAttribute(true)] public sealed class ZoneIdentityPermissionAttribute : CodeAccessSecurityAttribute
The scope of the declaration that is allowed depends on the SecurityAction that is used.
In the .NET Framework versions 1.0 and 1.1, demands on the identity permissions are effective even when the calling assembly is fully trusted. That is, although the calling assembly has full trust, a demand for an identity permission fails if the assembly does not meet the demanded criteria. In the .NET Framework version 2.0, demands for identity permissions are ineffective if the calling assembly has full trust. This assures consistency for all permissions, eliminating the treatment of identity permissions as a special case.
The security information declared by a security attribute is stored in the metadata of the attribute target and is accessed by the system at run time. Security attributes are used only for declarative security. For imperative security, use the corresponding permission class.
The following example of a declarative attribute shows the correct way to request ZoneIdentityPermission and states that you must have at least this permission to run your code. Code will run only if executed from the local computer.
The following example shows how to demand that the calling code has ZoneIdentityPermission at link time. Code will run only if executed from the local computer.
