add object to List. Msg "No constructor accepts 3 args

Question

I have a List<T> object that is a collection of custom objects and when I attempt to add my custom object to the list, it it tells me "myOject does not contain a constructor that takes 3 arguments".  But the thing is that myObject has only one constructor and it DOES take 3 args.

Here's the definition for myObject.

    class myObject
    {
        #region variables
        private Int64 _id;
        private Int64 _origID;
        private String _name;
        #endregion
        #region properties
        public Int64 id
        {
            get { return this._id; }
        }
        public Int64 origID
        {
            get { return this._origID; }
        }
        public String name
        {
            get { return this._name; }
        }
        #endregion
        #region methods
        public void myObject(Int64 id, Int64 origID, String name) //  <-- Constructor
        {
            this._id = id;
            this._origID = origID;
            this._name = name;
        }
        #endregion
    }

And here's the attempt to add it to the list:

List<myObject> obj = new List<myObject>();
for (i=0,i<cat.Count,i++){
  obj.Add(new myObj(i, cat.id, cat.name));  //<-- This line throws an error at compile time as noted above
}
