Represents an operating system process thread.
Assembly: System (in System.dll)
Thetype exposes the following members.

|CanRaiseEvents||Gets a value indicating whether the component can raise an event. (Inherited from Component.)|
|Container||Gets the IContainer that contains the Component. (Inherited from Component.)|
|CurrentPriority||Gets the current priority of the thread.|
|DesignMode||Gets a value that indicates whether the Component is currently in design mode. (Inherited from Component.)|
|Events||Gets the list of event handlers that are attached to this Component. (Inherited from Component.)|
|Id||Gets the unique identifier of the thread.|
|IdealProcessor||Sets the preferred processor for this thread to run on.|
|PriorityBoostEnabled||Gets or sets a value indicating whether the operating system should temporarily boost the priority of the associated thread whenever the main window of the thread's process receives the focus.|
|PriorityLevel||Gets or sets the priority level of the thread.|
|PrivilegedProcessorTime||Gets the amount of time that the thread has spent running code inside the operating system core.|
|ProcessorAffinity||Sets the processors on which the associated thread can run.|
|Site||Gets or sets the ISite of the Component. (Inherited from Component.)|
|StartAddress||Gets the memory address of the function that the operating system called that started this thread.|
|StartTime||Gets the time that the operating system started the thread.|
|ThreadState||Gets the current state of this thread.|
|TotalProcessorTime||Gets the total amount of time that this thread has spent using the processor.|
|UserProcessorTime||Gets the amount of time that the associated thread has spent running code inside the application.|
|WaitReason||Gets the reason that the thread is waiting.|
|CreateObjRef||Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)|
|Dispose()||Releases all resources used by the Component. (Inherited from Component.)|
|Dispose(Boolean)||Releases the unmanaged resources used by the Component and optionally releases the managed resources. (Inherited from Component.)|
|Equals(Object)||Determines whether the specified object is equal to the current object. (Inherited from Object.)|
|Finalize||Releases unmanaged resources and performs other cleanup operations before the Component is reclaimed by garbage collection. (Inherited from Component.)|
|GetHashCode||Serves as the default hash function. (Inherited from Object.)|
|GetLifetimeService||Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)|
|GetService||Returns an object that represents a service provided by the Component or by its Container. (Inherited from Component.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|InitializeLifetimeService||Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)|
|MemberwiseClone()||Creates a shallow copy of the current Object. (Inherited from Object.)|
|MemberwiseClone(Boolean)||Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.)|
|ResetIdealProcessor||Resets the ideal processor for this thread to indicate that there is no single ideal processor. In other words, so that any processor is ideal.|
|ToString||Returns a String containing the name of the Component, if any. This method should not be overridden. (Inherited from Component.)|
Use to obtain information about a thread that is currently running on the system. Doing so allows you, for example, to monitor the thread's performance characteristics.
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.
A thread is a path of execution through a program. It is the smallest unit of execution that Win32 schedules. It consists of a stack, the state of the CPU registers, and an entry in the execution list of the system scheduler.
A process consists of one or more threads and the code, data, and other resources of a program in memory. Typical program resources are open files, semaphores, and dynamically allocated memory. Each resource of a process is shared by all that process's threads.
A program executes when the system scheduler gives execution control to one of the program's threads. The scheduler determines which threads should run and when. A lower-priority thread might be forced to wait while higher-priority threads complete their tasks. On multiprocessor computers, the scheduler can move individual threads to different processors, thus balancing the CPU load.
Each process starts with a single thread, which is known as the primary thread. Any thread can create additional threads. All the threads within a process share the address space of that process.
The primary thread is not necessarily located at the first index in the collection.
Starting with the .NET Framework version 2.0, the ability to reference performance counter data on other computers has been eliminated for many of the .NET Framework methods and properties. This change was made to improve performance and to enable non-administrators to use the class. As a result, some applications that did not get exceptions in earlier versions of the .NET Framework may now get a NotSupportedException. The methods and properties affected are too numerous to list here, but the exception information has been added to the affected member topics.
The threads of a process execute individually and are unaware of each other unless you make them visible to each other. Threads that share common resources, however, must coordinate their work by using semaphores or another method of interprocess communication.
The HostProtectionAttribute attribute applied to this type or member has the following Resources property value: SelfAffectingProcessMgmt | SelfAffectingThreading. The HostProtectionAttribute does not affect desktop applications (which are typically started by double-clicking an icon, typing a command, or entering a URL in a browser). For more information, see the HostProtectionAttribute class or SQL Server Programming and Host Protection Attributes.
Windows 8.1, Windows Server 2012 R2, Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
