Retrieve version information

[Steve Barnett]

I'm trying to put together a class that retrieves version information from
my assembly and am having a problem. The code below happily retrieves the
AssemblyTitle and AssemblyDescrip tion but fails to retrieve the Version
number. Both of these are specified in the AssemblyInfo.cs file, so I can't
see why I can't get the version umber. Any suggestions?

Thanks
Steve

using System;
using System.Collecti ons.Generic;
using System.Text;
using System.Reflecti on;

namespace Lucidus.IPM.IPM
{
class VersionInformat ion
{
public static string ProductDescript ion()
{
Assembly currentAssembly = Assembly.GetExe cutingAssembly( );
Type attrType = typeof(Assembly DescriptionAttr ibute);

object[] attrs = currentAssembly .GetCustomAttri butes(attrType,
false);
if (attrs.Length 0)
{
AssemblyDescrip tionAttribute desc =
(AssemblyDescri ptionAttribute) attrs[0];
return desc.Descriptio n;
}
else
{
return "";
}
}

public static string ProductVersion( )
{
Assembly currentAssembly = Assembly.GetExe cutingAssembly( );
Type attrType = typeof(Assembly VersionAttribut e);

// *************** ********Always fails to get version
object[] attrs = currentAssembly .GetCustomAttri butes(attrType,
false);
if (attrs.Length 0)
{
AssemblyVersion Attribute desc =
(AssemblyVersio nAttribute)attr s[0];
return desc.Version;
}
else
{
return "0.0";
}
}

public static string ProductName()
{
Assembly currentAssembly = Assembly.GetExe cutingAssembly( );
Type attrType = typeof(Assembly ProductAttribut e);

object[] attrs = currentAssembly .GetCustomAttri butes(attrType,
false);
if (attrs.Length 0)
{
AssemblyProduct Attribute desc =
(AssemblyProduc tAttribute)attr s[0];
return desc.Product;
}
else
{
return "";
}
}

public static string ProductTitle()
{
Assembly currentAssembly = Assembly.GetExe cutingAssembly( );
Type attrType = typeof(Assembly TitleAttribute) ;

object[] attrs = currentAssembly .GetCustomAttri butes(attrType,
false);
if (attrs.Length 0)
{
AssemblyTitleAt tribute desc =
(AssemblyTitleA ttribute)attrs[0];
return desc.Title;
}
else
{
return "";
}
}

public static string ProductId()
{
Assembly currentAssembly = Assembly.GetExe cutingAssembly( );
string prodId = ProductTitle() + " Version " + ProductVersion( );

System.Windows. Forms.MessageBo x.Show(prodId);

return prodId;
}

}
}

A long time ago, somewhere deep within the msdn docs, I read that the
AssemblyVersion Attribute is some kind of special attribute that you
cannot retrieve like other attributes. You have to use something like that:

public string ProductVersion( ) {
return Assembly.GetExe cutingAssembly( ).GetName().Ver sion.ToString() ;
}

... haven't tested it, but should work. As far as I know, that's the
easiest way to get at the version information specified in the
AssemblyVersion "Attribute" .

Just when I thought I was starting to get a handle on this stuff, they go
and throw me a curve-ball like this.

Worked perfectly, thanks.
