Try it

public class Program

	{
		Type clsType = typeof(Program);

        Assembly assy = clsType.Assembly;

        String assyName = assy.GetName().Name;

        bool isdef = assy.IsDefined(typeof(AssemblyDescriptionAttribute));

        if (isdef)
        {
            Console.WriteLine("The AssemblyDescription attribute is defined for assembly {0}.", assyName);

			//C# Extension Method: Assembly - GetCustomAttribute
            AssemblyDescriptionAttribute adAttr = (AssemblyDescriptionAttribute)assy.GetCustomAttribute(typeof(AssemblyDescriptionAttribute));

            if (adAttr != null)
                Console.WriteLine("The description is \"{0}\".", adAttr.Description);
            else
                Console.WriteLine("The description could not be retrieved.");
        }
        else
            Console.WriteLine("The AssemblyDescription attribute is not defined for assembly {0}.", assyName);
	}
