Failure using ilasm, but no reason given

Question

I am trying to use `ILASM` and the process seems to abort with the following message: ``` ***** FAILURE ***** ``` How can I find out why it has failed? Can I turn on verbose messages or is there a log file I can look at?

Accepted Answer

While I realise that this is probably too late to help the question author now, I will leave these details here in case it helps someone in the future.

I had a similar problem recently where `Ildasm` would enable me to disassemble some DLLs to ILs, but `Ilasm` would not let me reassemble them into DLLs. Like the question author, my console output was very unhelpful, just stating:

```
***** FAILURE *****
```

But without any reasons listed.

In my case, it was a simple error, where I had copied my Strong Name Key file into the wrong directory. After I realised and put it into the correct location, `Ilasm` could access it successfully and was therefore able to reassemble my DLLs.

I think that it is a real shame that this basic error wasn't mentioned in an error output... it's one of the first things that I could think had gone wrong... or maybe that's why it wasn't listed... because it was easily fixed?

UPDATE >>>

One way that you can tell if you have this exact problem or not, is to look at the Console Window output... with no valid Strong Name Key file, `Ilasm` stops at the end of the Assembled method ... section, eg. every line will have the following (or similar) on it:

```
Assembled method Namespace.SubNamespace.ClassName::MethodName
```

If your output has the following lines in it then you probably have a different problem to this one as it should be missing from the output when there is no Strong Name Key file:

```
Creating PE file

Emitting classes:
```
