c# 4.0 - C# Getting Parent Assembly Name of Calling Assembly -

-

i've got c# unit test application i'm working on. there 3 assemblies involved - assembly of c# app itself, second assembly app uses, , third assembly that's used second one.

so calls go this:

first assembly ------> second assembly---------> third assembly.

what need in third assembly name of fist assembly called second assembly.

assembly.getexecutingassembly().manifestmodule.name assembly.getcallingassembly().manifestmodule.name

returns name of second assembly. , 

assembly.getentryassembly().manifestmodule.name

return null

does know if there way assembly name of first assembly?

as per other users demand here put code. not 100% code follow of code this.

namespace firstassembly{ public static xcass {         public static stream openresource(string name)         {             return reader.openresource(assembly.getcallingassembly(), ".resources." + name);         } } }  using firstassembly; namespace secondassembly{ public static class b   { public static stream filenamefromtype(string name)  { return = a.openresource(string name); } } }

and test project method

using secondassembly; namespace thirdassembly{ public class testc {   [testmethod()]         public void stremsiztest()         {             // arrange             var stream = b.filenamefromtype("validmetadata.xml");             // assert             assert.isnotnull(stream , "the stream  object should not null.");         } } }

i guess should able this:

using system.diagnostics; using system.linq;  ...  stackframe[] frames = new stacktrace().getframes(); string initialassembly = (from f in frames                            select f.getmethod().reflectedtype.assemblyqualifiedname                          ).distinct().last();

this assembly contains first method started first started in current thread. if you're not in main thread can different entryassembly, if understand situation correctly should assembly looking for.

you can actual assembly instead of name this:

assembly initialassembly = (from f in frames                            select f.getmethod().reflectedtype.assembly                          ).distinct().last();

edit - of sep. 23rd, 2015

please, notice 

getmethod().reflectedtype

can null, retrieving assemblyqualifiedname throw exception. example, that's interesting if 1 wants check vanilla c.tor dedicated orm (like linq2db, etc...) poco class.

i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
