mscorlib 2.0.0.0 4.0.0.0 System.Security.Permissions.CodeAccessSecurityAttribute System.AttributeUsage(System.AttributeTargets.Assembly | System.AttributeTargets.Class | System.AttributeTargets.Struct | System.AttributeTargets.Constructor | System.AttributeTargets.Method | System.AttributeTargets.All, AllowMultiple=true, Inherited=false) System.Runtime.InteropServices.ComVisible(true)

This class is used to ensure that callers are registered in the global assembly cache (GAC).

The scope of the declaration that is allowed depends on the value 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, .

Starting with the net_v40_long, 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.

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

- Constructor

  The constructor calls the base class to validate the value.

  This constructor associates a (for example, Demand) with the .

  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. Use for imperative security.

- Method
  2.0.0.0
  4.0.0.0
  System.Security.IPermission

  This method should be called only by the security system, never by application code.

  At compile time, attributes convert security declarations to a serialized form in metadata. Declarative security data in metadata is created from the permission returned by this method.

  Creates a new object.

  A that corresponds to this attribute.
