getting the GUID from of a loaded assembly

[Ron M. Newman]

Hi: How do I get the GUID string out of an assembly? (I have it loaded and
referenced from an Assembly obect).

This is an attribute in the Assembly Manifest. You get to it by getting an
instance of the System.Reflection.Assembly class, using:

System.Reflection.Assembly assembly = Assembly.GetExecutingAssembly();

Then you get an Attribute from the assembly using the
Assembly.GetCustomAttributes method:

((System.Runtime.InteropServices.GuidAttribute)ass embly.GetCustomAttributes(
typeof(System.Runtime.InteropServices.GuidAttribut e),false)[0]).Value

Note that you can use this method to get any of the various attributes in
the Assembly, as long as you know the type of the attribute, and what member
of the class you want to get at.

[assembly: Guid("6a6bf2ba-b251-492d-83c1-def446287453")]
[assembly: AssemblyVersion("1.0.0.0")]
[assembly: AssemblyFileVersion("1.0.0.0")]

Using this method I am able to read "Guid", "AssemblyFileVersion", but NOT
"AssemblyVersion". Any ideas why that is? is it not going into the compiled
file?

I'm getting "index out of array" indicating this has not been found:

this.version =
((AssemblyVersionAttribute)this.myAssembly.GetCust omAttributes(typeof(AssemblyVersionAttribute),
false)[0]).Version;

The AssemblyVersion gets special treatment as it becomes part of the
full assembly name. You can retrieve it with
myAssembly.GetName().Version.

Please reply only to the newsgroup.

Use the GetName() method of the Assembly class to get this:

string name = assembly.GetName().Name;
string version = assembly.GetName().Version.ToString(4);
