1. <mx:RemoteObject>控件访问

<mx:RemoteObject id=

"ro1"

 destination=

"fluorine"

 source=

"ServiceLibrary1.GameTask"

 fault=

"onFault(event)"

>
 <mx:method name=

"GetGame"

 result=

"onResult(event)"

></mx:method>
 <mx:method name=

"GetDataTable"

 result=

"onDataTableResult(event)"

></mx:method>
 <mx:method name=

"GetDataSet"

 result=

"onDataSetResult(event)"

></mx:method>
</mx:RemoteObject>

2. 代码直接访问

private function

 onCodeClick(event:MouseEvent):

void

{
 

var

nc:NetConnection = 

new

NetConnection();
 
 

var

responder:Responder = 

new

Responder(onCodeResult,onCodeStatus);
 
 nc.objectEncoding = ObjectEncoding.AMF3;
 
 nc.connect(

"http://localhost:4608/Web/gateway.aspx"

);
 
 nc.call(

"ServiceLibrary1.GameTask.GetDataSet"

,responder);
}

private function

 onCodeResult(result:Object):

void

{
 

this

.dataGrid1.dataProvider = result.myTable2  

as

  ArrayCollection;
}

private function

 onCodeStatus(event:Object):

void

{
 

trace

(

"Error"

);
}

3. 接收返回的对象

可以创建一个与服务器端对象一样结构的AS3对象来接收返回值，或直接用Object来接收

private function

 onResult(event:ResultEvent):

void

{
 

var

obj:Object = event.result  

as

  Object;
 

this

.lblResult.text = obj.Name;
}

4. 接收返回的DataTable

服务器端的DataTable，在Flex端可以转换为ArrayCollection；需要注意的是，服务器端要在该方法前声明[DataTableType(remoteClass:String)]

private function

 onClick(event:MouseEvent):

void

{
 ro1.GetDataTable();
}

private function

 onDataTableResult(event:ResultEvent):

void

{
 

this

.dataGrid1.dataProvider = event.result  

as

  ArrayCollection;
}

5. 接收返回的DataSet

DataSet包含有多个DataTable，在服务器端返回DataSet方法时，需要加入一个DataSetType和若干个DataTableType声明，例如：

[DataSetType(

"ServiceLibrary1.DSClass"

)]
[DataTableType(

"group1"

, 

"myTable1"

, 

"ServiceLibrary1.Game"

)]
[DataTableType(

"group2"

, 

"myTable2"

, 

"ServiceLibrary1.Game"

)]

public

DataSet GetDataSet()
{
        DataSet ds = 

new

DataSet();
        DataTable dt1 = ds.Tables.Add(

"group1"

);

//……

        DataTable dt2 = ds.Tables.Add(

"group2"

);

//……

}

这里的DataSetType所定义的DSClass，好像并不需要有这样一个实体类对应，随便写个都没什么问题；DataTableType的参数是DataTableType(表名,引用时的属性名,相应的类名)

private function

 onClick(event:MouseEvent):

void

{
 ro1.GetDataSet();
}

private function

 onDataSetResult(event:ResultEvent):

void

{
 

this

.dataGrid1.dataProvider = event.result.myTable2  

as

  ArrayCollection;
}

6. 接收返回的对象数组(Object[])

对象数组可以直接用Flex端的Array来接收

private function

 onCodeResult(result:Array):

void

{
 

this

.dataGrid1.dataProvider = result;
}

7. 接收返回的List<OBJECT>

List<OBJECT> 可以直接用Flex端的ArrayCollection来接收

private function

 onCodeResult(result:ArrayCollection):

void

{
 

this

.dataGrid1.dataProvider = result;
}
