Yan,

I think you had us all scratching our heads with this part

how do i create infosymbol with C#

Now that we know you really mean ActionScript code and not C# it a little easier to answer your question.

Here is the proper syntax for your code:

private function addsymbol():void{
    var myGraphic:Graphic=new Graphic(new MapPoint(66669.794213,42498.544789),infoSymbol1,{myphone: "123"});
    myGraphicsLayer.add(myGraphic);
   }

     myGraphic.attributes=new ArrayCollection([
                                     {myphone: "123"}
                                          ]);

Yan,

The way that I suggested in the last post works perfectly but if you must build the attributes separately than here is how

var myGraphic:Graphic=new Graphic(new MapPoint(66669.794213,42498.544789)); 
myGraphic.symbol=infoSymbol1;
var attribs:Object = {myphone: "123"};
myGraphic.attributes=attribs;
myGraphicsLayer.add(myGraphic);

myGraphic.attributes can be a Arraycollection?

Yan,

If you look at the documentation for a graphic object it is wanting an Object for the attributes property.
