c# - How to Use Reflection to Access Non-Public List and Its Non-Public Elements -

i need access list elements within array "message" strings, so:

string msg0 = sender.synchelper.uploadsyncprogresslist[0].results.exception.message; string msg1 = sender.synchelper.uploadsyncprogresslist[1].results.exception.message; ... 

i given "sender" object (which of type "object"). rest (synchelper, uploadsyncprogresslist, results, exception , message) non-public. these, class types of non-public types (except "exception").

this image shows visual representation of problem.

i have managed use reflection list variable "uploadsyncprogresslist" following code, stuck on how loop through list elements "messages" string:

propertyinfo synchelperinfo = sender.gettype().getproperty("synchelper", system.reflection.bindingflags.public | system.reflection.bindingflags.nonpublic | system.reflection.bindingflags.instance); object synchelper = synchelperinfo.getvalue(sender, null);  propertyinfo uploadprogresssynclistinfo = synchelper.gettype().getproperty("uploadsyncprogresslist", system.reflection.bindingflags.public | system.reflection.bindingflags.nonpublic | system.reflection.bindingflags.instance); object uploadprogresssynclist = uploadprogresssynclistinfo.getvalue(synchelper, null); 

how loop through "uploadprogresssynclist" elements "message" strings?

i doing because need access low-level network error messages hidden in 3rd party library.

thanks in advance!

you have few options here.

as uploadsyncprogresslist type of list<esri...eventargs> implements following collection interfaces

generic

• ilist<t>
• ienumerable<t>
• icollection<t>
• ireadonlylist<t>
• ireadonlycollection<t>

non generic

• ienumerable
• icollection
• ilist

so if eventargs in context public can cast result uploadprogresssynclist of generic interface

eg

ilist<esri...eventargs> synclist = (ilist<esri...eventargs>)uploadprogresssynclist; 

you can use of generic interface above suits needs

if event arg type not public non generic choice

ilist synclist = (ilist)uploadprogresssynclist; 

using ilist ilist<t> , ireadonlylist<t> interface retrieve via indexes

eg

var arg1 = synclist[0]; 

for of above can iterate using foreach

eg

foreach(var arg in synclist) {     //your logic arg }
