The SecurityPermissionAttribute type exposes the following members.
| Name | Description | |
|---|---|---|
|
SecurityPermissionAttribute | Initializes a new instance of the SecurityPermissionAttribute class with the specified SecurityAction. |
| Name | Description | |
|---|---|---|
|
Action | Gets or sets a security action. (Inherited from SecurityAttribute.) |
|
|
Assertion | Gets or sets a value indicating whether permission to assert that all this code's callers have the requisite permission for the operation is declared. |
|
|
BindingRedirects | Gets or sets a value that indicates whether code has permission to perform binding redirection in the application configuration file. |
|
|
ControlAppDomain | Gets or sets a value indicating whether permission to manipulate AppDomain is declared. |

SerializationFormatter | Gets or sets a value indicating whether code can use a serialization formatter to serialize or deserialize an object. |
|
|
SkipVerification | Gets or sets a value indicating whether permission to bypass code verification is declared. |
|
|

UnmanagedCode | Gets or sets a value indicating whether permission to call unmanaged code is declared. |
|
|
Unrestricted | Gets or sets a value indicating whether full (unrestricted) permission to the resource protected by the attribute is declared. (Inherited from SecurityAttribute.) |
| Name | Description | |
|---|---|---|
|
|
CreatePermission | Creates and returns a new SecurityPermission. (Overrides SecurityAttribute.CreatePermission().) |
|
|
Equals | Infrastructure. Returns a value that indicates whether this instance is equal to a specified object. (Inherited from Attribute.) |
|
Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
|
|
GetHashCode | Returns the hash code for this instance. (Inherited from Attribute.) |
|
|
GetType | Gets the Type of the current instance. (Inherited from Object.) |
|
|
IsDefaultAttribute | When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class. (Inherited from Attribute.) |
|
|
Match | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object. (Inherited from Attribute.) |
|
|
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
|
|
ToString | Returns a string that represents the current object. (Inherited from Object.) |
| Name | Description | |
|---|---|---|
|
_Attribute.GetIDsOfNames | Maps a set of names to a corresponding set of dispatch identifiers. (Inherited from Attribute.) |
|
|
_Attribute.GetTypeInfo | Retrieves the type information for an object, which can be used to get the type information for an interface. (Inherited from Attribute.) |
|
|
_Attribute.GetTypeInfoCount | Retrieves the number of type information interfaces that an object provides (either 0 or 1). (Inherited from Attribute.) |
|
|
_Attribute.Invoke | Provides access to properties and methods exposed by an object. (Inherited from Attribute.) |
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. |
