SiteIdentityPermissionAttribute Class


Allows security actions for SiteIdentityPermission to be applied to code using declarative security. This class cannot be inherited.

Namespace:   System.Security.Permissions
Assembly:  mscorlib (in mscorlib.dll)


[AttributeUsageAttribute(AttributeTargets.Assembly | AttributeTargets.Class | AttributeTargets.Struct | AttributeTargets.Constructor | AttributeTargets.Method, 
	AllowMultiple = true, Inherited = false)]
public sealed class SiteIdentityPermissionAttribute : CodeAccessSecurityAttribute


Initializes a new instance of the SiteIdentityPermissionAttribute class with the specified SecurityAction.


Gets or sets a security action.(Inherited from SecurityAttribute.)


Gets or sets the site name of the calling code.


When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)


Gets or sets a value indicating whether full (unrestricted) permission to the resource protected by the attribute is declared.(Inherited from SecurityAttribute.)


Creates and returns a new instance of SiteIdentityPermission.(Overrides SecurityAttribute.CreatePermission().)


This API supports the product infrastructure and is not intended to be used directly from your code. Returns a value that indicates whether this instance is equal to a specified object.(Inherited from Attribute.)


Returns the hash code for this instance.(Inherited from Attribute.)


Gets the Type of the current instance.(Inherited from Object.)


When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)


When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)


Returns a string that represents the current object.(Inherited from Object.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr)

Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)


Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr)

Provides access to properties and methods exposed by an object.(Inherited from Attribute.)

Site identity is only defined for code from URLs with the protocols of HTTP, HTTPS, and FTP. A site is the string between the "//" after the protocol of a URL and the following "/", if present, for example, in the URL This excludes port numbers. If a given URL is, the site is, not

Sites can be matched exactly, or by a wildcard ("*") prefix at the dot delimiter. For example, the site name string * matches as well as Without a wildcard, the site name must be a precise match. The site name string * will match any site, but will not match code that has no site evidence.


Starting with the .NET Framework 4, identity permissions are not 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 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.
