ThreadStart Delegate

 

Represents the method that executes on a Thread.

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

[<ComVisibleAttribute(true)>]
type ThreadStart = 
    delegate of unit -> unit

When a managed thread is created, the method that executes on the thread is represented by a ThreadStart delegate or a ParameterizedThreadStart delegate that is passed to the Thread constructor. The thread does not begin executing until the Thread.Start method is called. Execution begins at the first line of the method represented by the ThreadStart or ParameterizedThreadStart delegate.

System_CAPS_noteNote

Visual Basic and C# users can omit the ThreadStart or ParameterizedThreadStart delegate constructor when creating a thread. In Visual Basic, use the AddressOf operator when passing your method to the Thread constructor; for example, Dim t As New Thread(AddressOf ThreadProc). In C#, simply specify the name of the thread procedure. The compiler selects the correct delegate constructor.

System_CAPS_noteNote

In version 2.0 of the .NET Framework, creating a ThreadStart delegate for a static method in C++ requires only one parameter: the address of the callback method, qualified by the class name. In earlier versions two parameters were required when creating a delegate for a static method: zero (null) and the method address. For an instance method, all versions require two parameters: the instance variable and the method address.

The following code example shows the syntax for creating and using a ThreadStart delegate with an instance method and with a static method.

For another simple example that demonstrates how to create a ThreadStart delegate, see the Thread.Start() method overload. For more information about thread creation, see Creating Threads and Passing Data at Start Time.
