A tool to view C++/CLI assembly attributes

P: n/a
Hi,

I have a C++/CLI DLL which I marked with [assembly:
AssemblyVersionAttribute( "1.0.0.0" )] in a cpp file. Is there a standard
tool from Microsoft that takes a .DLL file and displays all the .NET
attributes of the assembly?

Thanks,

John

ildasm.exe will do that (aside from anything else it does).

Good morning John. Welcome to Microsoft Newsgroup Support service! My name
is Jialiang Ge [MSFT]. It's my pleasure to work with you on this issue.

As Pavel mentioned, ildasm.exe (MSIL Disassembler) is one standard tool
from Microsoft that can view all the .NET attributes of an assembly. You
can find it in .NET Framework SDK.

MSIL Disassembler (Ildasm.exe)
http://msdn.microsoft.com/en-us/libr...k1(VS.80).aspx

Ildasm.exe Tutorial (this tutorial is for .NET 1.1, but it also works for
.NET 2.0 and later)
http://msdn.microsoft.com/en-us/library/aa309387.aspx

In the menu File->Open of ildasm, we could locate the C++/CLI dll, load it.
Then in the View menu -MetaInfo -Show!, it would display all the
metadata info in the .NET assembly, including our AssemblyVersionAttribute
("1.0.0.0"):

CustomAttribute #7 (0c000043)
-------------------------------------------------------
CustomAttribute Type: 0a000005
CustomAttributeName: System.Reflection.AssemblyVersionAttribute :: instance
void .ctor(class System.String)
Length: 12
Value : 01 00 07 31 2e 30 2e 30 2e 30 00 00 1.0.0.0 <
ctor args: ("1.0.0.0")

One thing to be noticed is that, although most attributes in AssemblyInfo
can be found in the manifest, AssemblyVersionAttribute is an exception.
Compilers emit specific metadata for AssemblyVersionAttribute, rather than
emiting the custom attributes themselves. For more details, see the article:
http://blogs.msdn.com/adam_nathan/ar.../29/56645.aspx

John, please try it and let us know whether it's helpful to you.

Apart from ildasm, I'd like to share some other useful resources with you
to look at whenever you find free time. You might have come across these
before but it is just for your reference.

1. A commonly used tool: .NET Reflector
http://www.red-gate.com/products/reflector/
The original writer of the tool, Lutz Roeder, is a Microsoft engineer. In
the recent days, he declared to transfer the development of the tool to Red
Gate: http://blog.lutzroeder.com/

.NET Reflector can easily disassemble any .NET assembly. You could see the
AssemblyVersionAttribute["1.0.0.0"] by loading the .NET assembly,
right-clicking on the resultant node in reflector, and choose "Disassemble".

2. Assembly Viewer
http://www.codeproject.com/KB/dotnet/asmex.aspx
An open source solution to view the .NET assembly metadata. It contains the
source code to parse a .NET assembly.

3. PEBrowsePro
http://www.smidgeonsoft.prohosting.com/
PEBrowsePro can not only analyze .NET meta, it also does a very good job to
parse native images.

And more...

In addition, if you are interested in how to do the above programmatically
in future, you may want to have a look at this online book:
http://www.vijaymukhi.com/documents/books/metadata/
or refer to the source code in Assembly Viewer
http://www.codeproject.com/KB/dotnet/asmex.aspx

Have a nice day!

Thank you for the replies. Ildasm is OK for me.

Cheers,
