1，获取自定义Object的属性

dgSiteList.columns.removeAll();//删除所有的column
dgSiteList.columns.addItem( gcDel); //加载删除column

//根据arraylist[0] 组装columns

var myObj:Object =arraylist[0];
var objInfo:Object = ObjectUtil.getClassInfo(myObj); 
var fieldName:Array = objInfo["properties"] as Array; 

for each(var q:QName in fieldName){ 

 
//q 属性名称，value 对应的值 
/* var value:String = myObj[q.localName] as String; 
trace(q+" "+value); */

var dc:GridColumn = new GridColumn(q.localName); 
dc.headerText = q.localName;
dc.dataField =q.localName;

dgSiteList.columns.addItem(dc);

} 

dgSiteList.dataProvider = arraylist;
