Example: Start a thread to execute an telnet program in an onshow event in the winform window. When the Abort button (button1_Click) is clicked, the thread is aborted and then continues to execute, and the file resources occupied by the current thread are released.

Key: parameterThread_t. Abort (); parameterThread_t. Join (); GC. Collect (); This means that the thread Abort () stops thread execution, Join (); The thread hangs until the thread aborts, and then GC reclaims resources.
