Check the code here http://msdn.microsoft.com/en-us/library/bfwhbey7.aspx

Excerpt:

        // Get the AClass type to access its metadata.
        Type clsType = typeof(AClass);
        // Get the type information for Win32CallMethod.
        MethodInfo mInfo = clsType.GetMethod("Win32CallMethod");
        if (mInfo != null)
        {
            // Iterate through all the attributes of the method.
            foreach(Attribute attr in
                Attribute.GetCustomAttributes(mInfo)) {
                // Check for the Obsolete attribute.
                if (attr.GetType() == typeof(ObsoleteAttribute))
                {
                    Console.WriteLine("Method {0} is obsolete. " +
                        "The message is:",
                        mInfo.Name);
                    Console.WriteLine("  \"{0}\"",
                        ((ObsoleteAttribute)attr).Message);
                }

                // Check for the Unmanaged attribute.
                else if (attr.GetType() == typeof(UnmanagedAttribute))
                {
                    Console.WriteLine(
                        "This method calls unmanaged code.");
                    Console.WriteLine(
                        String.Format("The Unmanaged attribute type is {0}.",
                                      ((UnmanagedAttribute)attr).Win32Type));
                    AClass myCls = new AClass();
                    myCls.Win32CallMethod();
                }
            }
        }
