Failed to map path

Write a read/write FileProgramUsing system. Web. httpcontext. Current. server. mappath ("/bin/webset. xml ")

Check the program immediately. I feel that there are no errors, so I can search for the program online and find the solution. You only need to debug it slowly. Solution 1: Always go

Path/bin/webset. XML can be set to relative path :~ /Bin/webset. xml solution 2: Use

System. Web. httpcontext. Current. Request. physicalapplicationpath + ("/bin/webset. xml ");

System. Web. httpcontext. Current. Request. physicalapplicationpath indicates the root directory of the project.
