SecurityPermissionAttribute Class

Definition

Warning

This API is now obsolete.

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

public ref class SecurityPermissionAttribute sealed : System::Security::Permissions::CodeAccessSecurityAttribute
[System.Runtime.InteropServices.ComVisible(true)]
[System.AttributeUsage(System.AttributeTargets.Assembly | System.AttributeTargets.Class | System.AttributeTargets.Constructor | System.AttributeTargets.Method | System.AttributeTargets.Struct, AllowMultiple=true, Inherited=false)]
[System.Obsolete("CAS support is not available with Silverlight applications.")]
[System.Serializable]

Remarks

Important

Partially trusted code is no longer supported. This attribute has no effect in .NET Core.

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.

When you use the SecurityPermissionAttribute class, follow the security action with the permission(s) that are being requested. Each security permission that can be requested, as defined in the SecurityPermissionFlag enumeration, has a corresponding property in the SecurityPermissionAttribute class. For example, to demand the ability to access unmanaged code, follow the demand statement with the property setting that is being requested, as follows: SecurityPermissionAttribute(SecurityAction.Demand, UnmanagedCode=true).

Note

An exception to the equivalence between the SecurityPermissionFlag enumeration and the SecurityPermissionAttribute properties is that the AllFlags enumeration value is represented by the Unrestricted property (inherited from the SecurityAttribute class). To demand all security permissions, specify Unrestricted=true.
