CompressedStack Class


Provides methods for setting and capturing the compressed stack on the current thread. This class cannot be inherited.

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


public sealed class CompressedStack : ISerializable


Captures the compressed stack from the current thread.


Creates a copy of the current compressed stack.


Determines whether the specified object is equal to the current object.(Inherited from Object.)


This API supports the product infrastructure and is not intended to be used directly from your code. Gets the compressed stack for the current thread.


Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetObjectData(SerializationInfo, StreamingContext)

Sets the SerializationInfo object with the logical context information needed to recreate an instance of this execution context.


Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodSystem_CAPS_staticRun(CompressedStack, ContextCallback, Object)

Runs a method in the specified compressed stack on the current thread.


Returns a string that represents the current object.(Inherited from Object.)

The compressed stack is a compact representation of all the code access security information on the call stack, such as Deny and Assert actions. For example, if a Deny action is two stack frames up from the current frame and there are no other code access security annotations between there and the current frame, the compressed stack records only that information, without having to serialize the entire call stack.

The CompressedStackclass is used internally by the SecurityContext class. For example, the SecurityContext.Capture method captures the compressed stack for the current call stack, along with impersonation and culture information. The SecurityContext class is used in turn by the ExecutionContext class to flow context across threads, for example when scheduling thread pool tasks.

This class is not used in ordinary application programming.
