If there is a evdokey_201103221556.txt file under the E:/phsftp/evdokey directory,

The Evdokey_201103221556.txt file is now written or read, and the garbled problem of writing or reading is resolved.

File contents such as:

zhangsan,23, Fujian    
LISI,30, Shanghai    
wangwu,43, Beijing    
laolin,21, Chongqing    
ximenqing,67, Guizhou    

The code is as follows:
