You keep asking these specific XML questions, and the answer to all of them, appears to be Xpath. Go to the w3 website, or any other site with XPath tutorials, and work through them.

Unless you only need this once, or that's the only thing you're going to need from this, I'd personally build an XML serializable model so you can deserialize your XML to objects and work with them. Then your model can provide anything from the data. You could use the abominable XSD.exe or something like Skeleton Crew[^] to build your model from your sample XML.
I'd tend to use this approach anyway (I love XML serialization), but if you only need one piece of info or you only need to look at files once then maybe XPath would be quickest.

Hi,
I'm trying to get the Assembly objects which are used by a particular executable, but I'm getting a FileNotFoundException when I try to load referenced assemblies.
public static void ProcessAssembly(string filename)
{
Assembly assembly = Assembly.LoadFrom(filename);
AssemblyName[] names = assembly.GetReferencedAssemblies();
foreach (AssemblyName name in names)
{
Assembly referenced = Assembly.Load(name);
ProcessReferencedAssembly(referenced);
}
}
The reason the Exception occurs is obviously because the referenced assembly is in the same folder as the assembly we're looking at, and not the executing assembly.
My question is, in general, how can I get the Assembly for these? The only (unreliable) way of doing this I can think of is to use the AssemblyName to guess the filename of the Assembly (e.g. add ".dll").
Thanks in advance!

Have you checked to see what name is output? Whether it is looking in the right place?
|
|

Yes, the message I get is:
{"Could not load file or assembly 'ReferencedAssembly, Version=1.0.2537.32659, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.":"ReferencedAssembly, Version=1.0.2537.32659, Culture=neutral, PublicKeyToken=null"}, which is less than helpful!
The Exception also had the following in the FusionLog property, which shows it's just trying to guess the filename itself:
LOG: Attempting download of new URL file:LOG: Attempting download of new URL file:LOG: Attempting download of new URL file:LOG: Attempting download of new URL file: Sorry I've changed the names of the assemblies for privacy reasons.
The actual location of the assembly would be F:\OtherApp\ReferencedAssembly.DLL
Let me know if I'm not being clear.

Not sure exactly what is happening because I just ran a simple mockup and it worked fine. Are you using something like satellite dlls?
|
|
|
|
|
No I'm not, can't think of anything I've done out of the ordinary.
To be clear the assemblies are as follows:
F:\MyAppPath\MyApp.exe - Executing Assembly (with sample code in original post)
F:\OtherApp\OtherApp.exe - The path to this is passed into the example method
F:\OtherApp\ReferencedAssembly.dll - Exception retrieving this Assembly.
I've tried this on a few assemblies now, and get the same thing each time. Needless to say it successfully creates the Assemblies for System, etc.

Does the InnerException yield any info?  Permissions?
Sorry without seeing more code, I'm running out of ideas.
Hang on, are the assemblies authored by yourself / team or are they third part components?
|
|
|
|
|
Unfortunately inner exception is null.
To reproduce it you really do only need the sample code being called in its own assembly, and another 2 assemblies in a different folder, one referencing the other (making sure it actually is referenced, (i.e. create an instance of an object from the referenced assembly.. if you don't actually use it, it doesn't seem to count).
Think I might just end up trying to manually find the file, if I get the exception.

Odd, that's a similar setup to what I used (I'm in the middle of writing a program and just inserted the code).

You can get my test solution(s) here. You'll have to change the code in MyApp to have the correct file path in.
By the way, thanks for helping me with this! 
|
|
|
|
|
Works fine on my machine, I modified the solution to contain all three projects, set the output path as well to a common location so that I didn't have to copy and paste. And added some code to dump the name to the console.
Screenshot can be seen here[^], and you're saying this fails on your computer? 
|
|
|
|
|
Ah, I believe that would work for me. The problem is when the executing assembly and assembly being "analysed" (with referenced assembly) are in different folders (hence why I used 2 solutions).
It may be that Assembly.Load isn't meant to be used in the way I'm using it, but that would surprise me, since I'm passing it a normal AssemblyName object.
|
|
|
|
|
Ah ok, I didn't realise that was the problem, I shall take another look.
|
|
|
|

Just tried what you say and it's bizarre, perhaps it's to do with the fact that the CLR looks in the directory, I'm not sure. Maybe this is a bug with the framework, I would think so since the docs don't state otherwise. But you're not the only one:
Person 1[^] and here[^].
I haven't read through this[^] page fully but it looks like it might be of interest to you.
|
|
|
|
|
Cheers, that page does look very handy, I'll have a full read of it sometime. I'll probably do what I suggested and try and work out the filename when Load doesn't work.
Thanks for all your help!

Good luck in that and thanks for pointing out this, will save me some head scratching in the future.

hi all, i made this code to make multithreads for one method and every thread take one packet to move but it didnot work, Is there any error in this code
private void btn_simulate_Click(object sender, EventArgs e)<br />
{<br />
for (int i = 0; i < lineArray.LineList.Count; i++)<br />
{<br />
packetsMovingThreadArray.Add(new Thread(threadProcedure));<br />
dataPacketsArray.Add(new Packet());<br />
}<br />
this.btn_simulate.Enabled = false;<br />
this.btn_stop.Enabled = true;<br />
movingPacketThreadFlag = true;<br />
for (int i = 0; i < lineArray.LineList.Count; i++)<br />
{<br />
((Thread)packetsMovingThreadArray[i]).Start();<br />
}<br />
}<br />
int simulationIndex = -1;<br />
private void threadProcedure()<br />
{<br />
simulationIndex++;<br />
Packet pack = ((Packet)dataPacketsArray[simulationIndex]);<br />
AdHocMobility.simulate(ref pack,((Line)lineArray.LineList[simulationIndex]),<br />
this);<br />
}<br />
private void btn_stop_Click(object sender, EventArgs e)<br />
{<br />
try<br />
{<br />
this.btn_stop.Enabled = false;<br />
this.btn_simulate.Enabled = true;<br />
packetsMovingThreadArray.Clear();<br />
foreach (Thread Th in packetsMovingThreadArray )<br />
{<br />
Th.Abort(); <br />
}<br />
simulationIndex = -1;<br />
movingPacketThreadFlag = false;<br />
Invalidate();<br />
}<br />
catch (Exception ex)<br />
{<br />
MessageBox.Show(ex.Message);<br />
}<br />
}
thanks

If "simulate()" is painting you can't do that from a worker thread
and
the way you are using simulationIndex does not look safe
in short you need to do some more reading on multi-thread concepts like synchronization. I recommend books by Jeffery Richter on that subject.

hi can u explain this statement ,
in simulate i called movePacket() and this method returns
new points for the packet and i draw it in onPaint()
and actually i want to ask what is the meaning of not safe to use simulationIndex
thanx

Multi-Threaded application almost always need one or more forms of "Syncrhonization[^]"
It's not something that can be explained in a few sentences in a forum message. Look at the link and the author [^]I suggested.

use System.Threading.ThreadStart delegate instead of Thread
|

Hi,
This is hard to explain, but it is a simple enough problem...
I have a large dataset (Class 'Dataset') that will be altered by a sequence of events (Abstract class Event, not events in the sense of delegate events). I need to be able to reconstruct the state of this dataset after any amount of events, so I designed an Event abstract class which will be extended for every type of event that can happen. An instance of the specific type is created, applied to the dataset, and stored in a list whenever an event occurs.
Now, it is quite important that the rest of my program does not modify any of the data without constructing an Event, otherwise if I recreate the dataset at that point in time (by re-applying all the events in my list) it will not be consistent with the original.
At the moment my Event has the abstract method Apply(Dataset data), which applies the changes for that event to the given dataset. However, this means I have to keep a most of Dataset's members public, and (besides being bad OO practice) if I or someone else accidentally modify any of them w/o an Event, it's going to be quite hard to debug.
My other option would be to include an overloaded method in Dataset that applies each Event accordingly, but I'm not sure how it will apply. For example, if I have extended Event to EventA, and do:
<br />
Event e = new EventA();<br />
<br />
Dataset.ApplyEvent (e);<br />
and Dataset has two ApplyEvent methods:
<br />
public void ApplyEvent (Event e) {}<br />
<br />
public void ApplyEvent (EventA e) {}<br />
Will the overloaded method for EventA be called? Or is there a simpler, elegant solution I'm not thinking of?
Sorry for the long post and thanks for your help
