[SerializableAttribute] [AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Constructor|AttributeTargets.Method, AllowMultiple = true, Inherited = false)] [ComVisibleAttribute(true)] public sealed class UIPermissionAttribute : CodeAccessSecurityAttribute
The scope of the declaration that is allowed depends on the SecurityAction that is used.
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 UIPermission for the ability to use the clipboard within your own application domain and states that you must have at least this permission to run your code.
The following example shows how to demand that the calling code has UIPermission at link time. Demands are typically made in managed libraries (DLLs) to help protect methods or classes from potentially harmful code.
