Apologies for spamming this site. I finally managed to get the info out of
Cecil that I was after.
The follow code can be used to iterate through all classes and methods and
dump out their Source File location.
My issue was loading the symbols. Other posts indicated that once the
assembly definition was loaded, all I had to do was call
asm.MainModule.ReadSymbols()
However, this caused errors for me.
I had to load the symbol file separately and then use this to load the
symbols for the MainModule, as follows:
MonoSymbolFile symFile =
MonoSymbolFile.ReadSymbolFile(monoAssembly + ".mdb");
ISymbolReader sr = (ISymbolReader)(new
Mono.Cecil.Mdb.MdbReader(asm.MainModule, symFile));
asm.MainModule.ReadSymbols(sr);
Hopefully the code below will save someone else time mucking around.
*I still have an outstanding question I am hoping someone can answer for
me. *
*I would like to use the MonoSymbolFile.Methods, a MethodEntry list.
MethodEntry has the source file. Where it fails for me, is that
GetRealName often returns a null. How can I retrieve the source file
location for a MethodEntry?*
