Encapsulates and propagates all security-related data for execution contexts transferred across threads. This class cannot be inherited.
Assembly: mscorlib (in mscorlib.dll)
Captures the security context for the current thread.
Creates a copy of the current security context.
Releases all resources used by the current instance of theclass.
Determines whether the specified object is equal to the current object.(Inherited from Object.)
Serves as the default hash function. (Inherited from Object.)
Determines whether the flow of the security context has been suppressed.
Determines whether the flow of the Windows identity portion of the current security context has been suppressed.
Restores the flow of the security context across asynchronous threads.
|Run(SecurityContext, ContextCallback, Object)|
Runs the specified method in the specified security context on the current thread.
Suppresses the flow of the security context across asynchronous threads.
Suppresses the flow of the Windows identity portion of the current security context across asynchronous threads.
Returns a string that represents the current object.(Inherited from Object.)
A WindowsIdentity and CompressedStack objects. This configuration allows the Windows identity and the security elements on the stack to be propagated automatically when the is copied and transferred across asynchronous threads.object captures all security-related information for a logical thread, including the information contained in the
The common language runtime (CLR) is aware of impersonation operations performed using only managed code, not of impersonation performed outside of managed code, such as through platform invoke to unmanaged code or through direct calls to Win32 functions. Only managed WindowsIdentity objects can flow across asynchronous points, unless the alwaysFlowImpersonationPolicy element has been set to true (<alwaysFlowImpersonationPolicy enabled="true"/>). Setting the alwaysFlowImpersonationPolicy element to true specifies that the Windows identity always flows across asynchronous points, regardless of how impersonation was performed. For more information about flowing unmanaged impersonation across asynchronous points, see <alwaysFlowImpersonationPolicy> Element.
This type implements the IDisposable interface. When you have finished using the type, you should dispose of it either directly or indirectly. To dispose of the type directly, call its Dispose method in a try/catch block. To dispose of it indirectly, use a language construct such as using (in C#) or Using (in Visual Basic). For more information, see the “Using an Object that Implements IDisposable” section in the IDisposable interface topic.
