SecuritySafeCriticalAttribute Class
Identifies types or members as security-critical and safely accessible by transparent code.
Assembly: mscorlib (in mscorlib.dll)
[AttributeUsageAttribute(AttributeTargets.Class | AttributeTargets.Struct | AttributeTargets.Enum | AttributeTargets.Constructor | AttributeTargets.Method | AttributeTargets.Field | AttributeTargets.Interface | AttributeTargets.Delegate, AllowMultiple = false, Inherited = false)] public sealed class SecuritySafeCriticalAttribute : Attribute
| Name | Description | |
|---|---|---|
![]() | SecuritySafeCriticalAttribute() | Initializes a new instance of the SecuritySafeCriticalAttribute class. |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | 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.) |
![]() | GetHashCode() | Returns the hash code for this instance.(Inherited from Attribute.) |
![]() | GetType() | |
![]() | 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(Object) | When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.) |
![]() | ToString() | Returns a string that represents the current object.(Inherited from Object.) |
| Name | Description | |
|---|---|---|
![]() ![]() | _Attribute.GetIDsOfNames(Guid, IntPtr, UInt32, UInt32, IntPtr) | Maps a set of names to a corresponding set of dispatch identifiers.(Inherited from Attribute.) |
![]() ![]() | _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.) |
![]() ![]() | _Attribute.GetTypeInfoCount(UInt32) | Retrieves the number of type information interfaces that an object provides (either 0 or 1).(Inherited from Attribute.) |
![]() ![]() | _Attribute.Invoke(UInt32, Guid, UInt32, Int16, IntPtr, IntPtr, IntPtr, IntPtr) | Provides access to properties and methods exposed by an object.(Inherited from Attribute.) |
Types or members that are marked with the SecuritySafeCriticalAttribute attribute can be accessed by partially trusted types and members. These partially trusted types and members can be within any assembly that is marked with the SecurityTransparentAttribute or AllowPartiallyTrustedCallersAttribute (APTCA) attribute, or they are partially trusted for other reasons, such as being loaded into partial trust. Code that is marked with the SecuritySafeCriticalAttribute must be subject to a rigorous security audit to ensure that it can be used safely in a secure execution environment. Security-safe-critical code must validate the permissions of callers to determine whether they have authority to access protected resources used by the code.
