. Net multithreading note (5): dedicated data TLS for threads

Thread Local Storage TLS)

In. netProgramStatic variables are globally visible (the entire application domain) data. A common static variable is visible and accessible to all threads in the application domain.

TLSIt refers to a structure in the online environment block used to store exclusive data in the thread. The thread in the process cannot access the TLS of another user.This ensures TLSData in the thread is shared globally, but invisible outside the thread.
