Member Function Documentation

Capture()

static SecurityContext System.Security.SecurityContext.Capture ( )

static

Captures the security context for the current thread.

Returns

The security context for the current thread.

Definition at line 410 of file SecurityContext.cs.

CreateCopy()

SecurityContext System.Security.SecurityContext.CreateCopy

(

)

Creates a copy of the current security context.

Returns

The security context for the current thread.

Exceptions

T:System.InvalidOperationException

The current security context has been previously used, was marshaled across application domains, or was not acquired through the M:System.Security.SecurityContext.Capture method.

Definition at line 370 of file SecurityContext.cs.

Dispose()

void System.Security.SecurityContext.Dispose

(

)

Releases all resources used by the current instance of the T:System.Security.SecurityContext class.

Implements System.IDisposable.

Definition at line 170 of file SecurityContext.cs.

IsFlowSuppressed()

static bool System.Security.SecurityContext.IsFlowSuppressed ( )

static

Determines whether the flow of the security context has been suppressed.

Returns

true if the flow has been suppressed; otherwise, false.

Definition at line 227 of file SecurityContext.cs.

IsWindowsIdentityFlowSuppressed()

static bool System.Security.SecurityContext.IsWindowsIdentityFlowSuppressed ( )

static

Determines whether the flow of the Windows identity portion of the current security context has been suppressed.

Returns

true if the flow has been suppressed; otherwise, false.

Definition at line 235 of file SecurityContext.cs.

RestoreFlow()

static void System.Security.SecurityContext.RestoreFlow ( )

static

Restores the flow of the security context across asynchronous threads.

Exceptions

T:System.InvalidOperationException

The security context is null or an empty string.

Definition at line 214 of file SecurityContext.cs.

Run()

static void System.Security.SecurityContext.Run ( SecurityContext  securityContext, ContextCallback  callback, object  state  )

static

Runs the specified method in the specified security context on the current thread.

Parameters

securityContext	The security context to set.
callback	The delegate that represents the method to run in the specified security context.
state	The object to pass to the callback method.

Exceptions

T:System.InvalidOperationException

securityContext is null.-or- securityContext was not acquired through a capture operation. -or- securityContext has already been used as the argument to a M:System.Security.SecurityContext.Run(System.Security.SecurityContext,System.Threading.ContextCallback,System.Object) method call.

Definition at line 260 of file SecurityContext.cs.

SuppressFlow()

static AsyncFlowControl System.Security.SecurityContext.SuppressFlow ( )

static

Suppresses the flow of the security context across asynchronous threads.

Returns

An T:System.Threading.AsyncFlowControl structure for restoring the flow.

Definition at line 181 of file SecurityContext.cs.

SuppressFlowWindowsIdentity()

static AsyncFlowControl System.Security.SecurityContext.SuppressFlowWindowsIdentity ( )

static

Suppresses the flow of the Windows identity portion of the current security context across asynchronous threads.

Returns

A structure for restoring the flow.
