Allows security actions for UrlIdentityPermission to be applied to code using declarative security. This class cannot be inherited.
Assembly: mscorlib (in mscorlib.dll)
[SerializableAttribute] [ComVisibleAttribute(true)] [AttributeUsageAttribute(AttributeTargets.Assembly|AttributeTargets.Class|AttributeTargets.Struct|AttributeTargets.Constructor|AttributeTargets.Method, AllowMultiple = true, Inherited = false)] public sealed class UrlIdentityPermissionAttribute : CodeAccessSecurityAttribute
The complete URL is considered, including the protocol (HTTP, HTTPS, FTP) and the file. For example, http://www.fourthcoffee.com/process/grind.htm is a complete URL.
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 UrlIdentityPermission and states that you must have the specified URL identity to run your code. Code will execute only if run from the specified URL.
The following example shows how to demand that the calling code has the specified URL identity at link time. Code will execute only if run from the specified URL.
