Thread(ParameterizedThreadStart, Int32)	Initializes a new instance of the Thread class, specifying a delegate that allows an object to be passed to the thread when the thread is started and specifying the maximum stack size for the thread.
Thread(ThreadStart)	Initializes a new instance of the Thread class.
Thread(ThreadStart, Int32)	Initializes a new instance of the Thread class, specifying the maximum stack size for the thread.

CurrentCulture	Gets or sets the culture for the current thread.
CurrentPrincipal	Gets or sets the thread's current principal (for role-based security).
CurrentThread	Gets the currently running thread.
CurrentUICulture	Gets or sets the current culture used by the Resource Manager to look up culture-specific resources at run time.

Methods

Abort()	Obsolete. Raises a ThreadAbortException in the thread on which it is invoked, to begin the process of terminating the thread. Calling this method usually terminates the thread.
Abort(Object)	Obsolete. Raises a ThreadAbortException in the thread on which it is invoked, to begin the process of terminating the thread while also providing exception information about the thread termination. Calling this method usually terminates the thread.
AllocateDataSlot()	Allocates an unnamed data slot on all the threads. For better performance, use fields that are marked with the ThreadStaticAttribute attribute instead.
AllocateNamedDataSlot(String)	Allocates a named data slot on all threads. For better performance, use fields that are marked with the ThreadStaticAttribute attribute instead.
BeginCriticalRegion()	Notifies a host that execution is about to enter a region of code in which the effects of a thread abort or unhandled exception might jeopardize other tasks in the application domain.
BeginThreadAffinity()	Notifies a host that managed code is about to execute instructions that depend on the identity of the current physical operating system thread.
DisableComObjectEagerCleanup()	Turns off automatic cleanup of runtime callable wrappers (RCW) for the current thread.
EndCriticalRegion()	Notifies a host that execution is about to enter a region of code in which the effects of a thread abort or unhandled exception are limited to the current task.
EndThreadAffinity()	Notifies a host that managed code has finished executing instructions that depend on the identity of the current physical operating system thread.
Equals(Object)	Determines whether the specified object is equal to the current object. (Inherited from Object)
Finalize()	Ensures that resources are freed and other cleanup operations are performed when the garbage collector reclaims the Thread object.
FreeNamedDataSlot(String)	Eliminates the association between a name and a slot, for all threads in the process. For better performance, use fields that are marked with the ThreadStaticAttribute attribute instead.
GetApartmentState()	Returns an ApartmentState value indicating the apartment state.

MemberwiseClone()	Creates a shallow copy of the current Object. (Inherited from Object)
MemoryBarrier()	Synchronizes memory access as follows: The processor executing the current thread cannot reorder instructions in such a way that memory accesses prior to the call to MemoryBarrier() execute after memory accesses that follow the call to MemoryBarrier().
