SecurityTransparentAttribute Class


Specifies that an assembly cannot cause an elevation of privilege.

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


[AttributeUsageAttribute(AttributeTargets.Assembly, AllowMultiple = false, 
	Inherited = false)]
public sealed class SecurityTransparentAttribute : Attribute


Initializes a new instance of the SecurityTransparentAttribute class.


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


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.)

Transparent assemblies can be accessed from partially trusted code and cannot expose access to any protected resources or functionality. Code in the assembly is not allowed to suppress code access security checks and cannot cause an elevation of privilege.


Transparency is enforced by the just-in-time compiler, not by the security infrastructure code. Applying this attribute to an assembly allows the assembly to access only transparent and security-safe-critical types and members regardless of its permission set, including full trust. Transparent code that accesses a security-critical type or member results in a MethodAccessException being thrown.
