When according to the TRM, in the debug window, set the XRSn pin to 1. No effect happens.

Does this set the XRSn pin to 1, shall use the code , cannot use the debug to modify the register directly?

I regret I don't understand what you are asking here.

Instead of writing to that bit directly through CCS, can you please write to that bit through your code in standalone mode? i.e. without the debug probe (and CCS) connected?

My purpose is to quick test of the Simulate external reset, writing to that bit directly through CCS. But found that didnot work as expected.

My question is why writing to that bit directly through CCS cannot work?

The reset mechanism works differently when the debug-probe is connected and CCS has control of the device. For example, in standalone mode, if you reset the device, it starts "free-running" the code. In debug mode, the debugger has control of the device and code can only be run through the debugger.
