Can only get the "Draft" stamp when insert customer stamp with C#+JS

Question

I am trying to insert customer stamp in batch files with C#+JS.
My JS works well in Acrobat. However, it doesn't work when use C#+JS. I always get the Acrobat's "Draft" stamp other than my own ones (the AP value is confirmed correct).
In c#, it runs as this ( with the objectype.InvokeMember())
1. initial an annotation with addAnnot first and get the properties object with method of getProp().
2. Set the type entry of the properties object as "Stamp"
3. With setProp(), modify the annotation to a Stamp annotation, and then get the properties object of the Stamp annotation.
4. Set the entries (rect, page, AP ) of the properties object. Then use setProp() again to modify the properties of the Stamp annotation.
The program runs without any error message. But I can only get the default stamp "Draft".
One thing I found so far, in JS console in Acrobat, if I set the AP properties AFTER set the annotation type to "Stamp", it also get the "Draft" stamp only. as this,
     annot = this.addAnnot();
     prop = annot.getProps();
     prop.type = "Stamp";
     annot.setProps(prop);
     prop = annot.getProps();
     prop.page = 0;
     prop.rect = [0, 0, 100, 100];
     prop.AP = "#xxxxxxxx";
     annot.setProps(prop);
If I set the prop.Ap before the forth line in above para, I can get the right stamp.
     annot = this.addAnnot();
     prop = annot.getProps();
     prop.type = "Stamp";
     prop.AP = "#xxxxxxxx";
     annot.setProps(prop);
     prop = annot.getProps();
     prop.page = 0;
     prop.rect = [0, 0, 100, 100];
     annot.setProps(prop);
Or, if I set the props in the typcial JS format like below, I also get the right one
annot = this.addAnnot({
type: stamp,
page: 0,
rect: [0,0,100,100]
AP: #xxxxxxxx)});
But, the problem is, in C#, the AP properties can only be set after set the annotation type as Stamp (step 4). I think this might be the reason, but I don't know how to get over this.
Please help. Thanks!

No, it can't – but you could do that yourself as part of the watermarking process (ie. Two watermarks or fields)
