AjaxPro V.6.2.16.1使用数组报错

在这Ajax风靡日子里，忍不住试用了一下新版的AjaxPro (AssemblyVersion: 6.2.16.1),谁知一测没点反应，Server端代码如下：

        [AjaxPro.AjaxMethod]
         public   object [] GetNumbers( int [] a,  double [] b)
         {
            object[] x = new object[2];
            x[0] = 0;
            x[1] = 0.0d;
            foreach(int i in a) x[0] = (int)x[0] + i;
            foreach(double i in b) x[1] = (double)x[1] + i;            

        }

脚本中AjaxTest.MyControl.GetNumbers([1,2,3],[1.1,2.2,3.3]).value调用异常

郁闷之余，发现AjaxPro.JavaScriptDeserializer.cs的internal static object DeserializeInternal(IJavaScriptObject o, Type type)方法出了问题

         internal   static   object  DeserializeInternal(IJavaScriptObject o, Type type)
         {

            //..
            if(o == null)
            {
                return null;
            }
            //

            else if(typeof(IJavaScriptObject).IsAssignableFrom(type))
            {
                return o;
            }

            //

             if (o is JavaScriptArray && (type.IsArray || type == typeof(System.Array)))
                {
                    return JavaScriptDeserializer.DeserializeArray((JavaScriptArray)o, type);
                }

             //..

}

因为满足 typeof (IJavaScriptObject).IsAssignableFrom(type),根本就没有执行到if (o is JavaScriptArray && (type.IsArray || type == typeof(System.Array))

解决方法:改为:

internal   static   object  DeserializeInternal(IJavaScriptObject o, Type type)
         {

            //...
            if(o == null)
            {
                return null;
            }
            //...
            //added
            else if ((type.IsArray || type == typeof(System.Array)) && o is JavaScriptArray)
            {
                return JavaScriptDeserializer.DeserializeArray((JavaScriptArray)o, type);
            }
            //end
            else if(typeof(IJavaScriptObject).IsAssignableFrom(type))
            {
                return o;
            }

               //...

                //removed 
//              if (o is JavaScriptArray && (type.IsArray || type == typeof(System.Array)))
//              {
//                   return JavaScriptDeserializer.DeserializeArray((JavaScriptArray)o, type);
//              }
                //end

                //..

}

就好了
