Reading P6 Activity ID (.xer and xml) via MPXJ for C#

Question

MPXJ Version:5.1.17

Q1: If I export my p6 file to .xer . When I use MPXJ to read the file , I got garbled text in c#.(It's Chinese text originally),but if i export p6 file to XML format, i can get the right Chinese text using MPXJ in c#. Is anyone have such experience?

Q2: How can I get P6 Activity ID using MPXJ? the return type of Task.ID is Integer.. but the ID in P6 is string. When I called MPXJ, I got

ID:6 // In XML, It's "A1010" , how can I get "A1010" ?

Answer 1

See my comment above regarding reporting the bug in reading the task name. To answer you second question the Activity ID is mapped into the Text1 attribute of the task: task.getText(1) should get you what you want.
