C # source code for express delivery Ticket No. Query

The source code has been tested by myself. There is no problem. You can query the express waybill number. Many supported express parcels are supported. yuantong Express, Shentong express, and yunda express support ticket number query, the program transmits parameters to the aiexpress (www.aikuaidi.cn) interface to query the Express bill number. I directly post the code to solve the problem of single development.
