[VB.Net] ThreadStart與ParameterizedThreadStart

若要建立一個不含參數的執行緒(thread)，使用ThreadStart這個委託函式即可；但是若要建立含有參數的執行緒，則須以ParameterizedThreadStart這個委託函式建立。

但是自.Net framework 2.0開始，只要方法不是overloading，compiler都會自行判斷要使用哪個方法建立執行緒，因此直接以一般方法建立即可，如︰

Dim thread1 As Thread = New Thread(AddressOf MyThread);
thread1.Start();

Dim thread2 As Thread = New Thread(New ThreadStart(AddressOf MyThread));
thread2.Start();

Dim thread3 As Thread = New Thread(AddressOf MyThreadWithParameter);
thread3.Start(myClass);

Dim thread4 As Thread = New Thread(New ParameterizedThreadStart(AddressOf MyThreadWithParameter));
thread4.Start(myClass);

以上四種方法都是可行的。
