[NAnt-users] Returning Values from a Custom Nant Task

[Swiss Steve]

I have written a simple NAnt custom task which I want to create property than
can then be used in my NAnt scripts.   My problem is I dont know how to
access this property from my scripts.   I have called the task so that it
populated its internal variables and then tried the following to access the
properties from my script

<echo message=${timestamp.basetimestamp}/>

Here is my custom task

namespace NAntTimeStamp
{
    [TaskName("timestamp")]
    public class NAntTimeStampTask : Task
    {
        private string t = null;
        private string tFile = null;
        private string post = null;
        private string pre = null;
        
        public void TestTask()
        {
           ExecuteTask();
        }

        [TaskAttribute("basetimestamp", Required = false)]
        [StringValidator(AllowEmpty = true)]
        public string timeStamp
        {
            get { return t; }
            set { t = value; }
        }

        [TaskAttribute("filetimestamp", Required = false)]
        [StringValidator(AllowEmpty = true)]
        public string fileTimeStamp
        {
            get { return tFile; }
            set { tFile = value; }
        }
        
        [StringValidator(AllowEmpty = true)]
        public string postFix
        {
            get { return post; }
            set { post = value; }
        }
        
        [TaskAttribute("prefix", Required = false)]
        [StringValidator(AllowEmpty = true)]
        public string preFix
        {
            get { return pre; }
            set { pre = value; }
        }
        
        protected override void ExecuteTask()
        {
            DateTime now = DateTime.Now;
            string current = now.ToString();
            tFile = current;
            StringBuilder  buffer = new StringBuilder();

            buffer.Append("v1.");
            buffer.Append(String.Format("{0:MM}", now.Month.ToString()));
            buffer.Append(".");
            buffer.Append(String.Format("{0:dd}", now.Day.ToString()));
            buffer.Append(".");
            buffer.Append(String.Format("{0:hh}", now.Hour.ToString()));
            buffer.Append(String.Format("{0:mm}", now.Minute.ToString()));
            buffer.Append(String.Format("{0:ss}", now.Second.ToString()));
       
            t = preFix + buffer + postFix;            
        }
              
    }
}
