Encapsulates and propagates all security-related data for execution contexts transferred across threads. This class cannot be inherited.
Assembly: mscorlib (in mscorlib.dll)
Thetype exposes the following members.
|Capture||Captures the security context for the current thread.|
|CreateCopy||Creates a copy of the current security context.|
|Dispose||Releases all resources used by the current instance of the class.|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|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||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|IsFlowSuppressed||Determines whether the flow of the security context has been suppressed.|
|IsWindowsIdentityFlowSuppressed||Determines whether the flow of the Windows identity portion of the current security context has been suppressed.|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|RestoreFlow||Restores the flow of the security context across asynchronous threads.|
|Run||Runs the specified method in the specified security context on the current thread.|
|SuppressFlow||Suppresses the flow of the security context across asynchronous threads.|
|SuppressFlowWindowsIdentity||Suppresses the flow of the Windows identity portion of the current security context across asynchronous threads.|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
A object captures all security-related information for a logical thread, including the information contained in the 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.
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.
