生活随笔收集整理的這篇文章主要介紹了 [原创]Flex 与 Asp.Net 通过 Remoting 方式进行通讯 (三) 小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.

五、復(fù)雜數(shù)據(jù)類型的通訊（http://xingfustar.cnblogs.com/)
????
????Remoting支持傳送數(shù)組、List、HashTable、Dictionary等多種復(fù)雜數(shù)據(jù)類型，本文以數(shù)組，Dictionary，HashTable為例，講解復(fù)雜數(shù)據(jù)類型的通訊。

（一）數(shù)組（http://xingfustar.cnblogs.com/)

1、.NET服務(wù)器端程序（http://xingfustar.cnblogs.com/)

????假設(shè)我們要做段程序，來獲取所有的用戶姓名。修改上節(jié)中的代碼，增加一個GetUsers方法。代碼如下：
????????public?string[]?GetArray()
????????{
????????????string[]?array?=?new?string[]{"張三","李四","王五"};

????????????return?array;
????????}
2、Flex客戶端程序（http://xingfustar.cnblogs.com/)

????在 Design 模式下添加，添加一個 Text文本控件，id為txtUsers，txt屬性為空，添加一個 Button控件，id為btnGetArray，Label屬性為?GetArray
????
????在 Source 模式下, 修改　mx:RemoteObject 標(biāo)簽，添加　
????<mx:method name="GetArray" result="RemoteResult(event)" fault="RemoteFault(event)"/>?
????修改腳本中 RemoteResult 方法，增加一個Case條件，代碼如下
????????????public?function?RemoteResult(re:ResultEvent):void
????????????{?
????????????????switch(re.currentTarget.name)
????????????????{
????????????????????case?"HelloWord":
????????????????????????var?str:String?=?re.result?as?String;
????????????????????????this.txtHelloWord.text?=?str;
????????????????????????break;
????????????????????case?"SayHello":
????????????????????????str?=?re.result?as?String;
????????????????????????this.txtSayHello.text?=?str;
????????????????????????break;
????????????????????case?"GetArray":
????????????????????????for(var?i:int=0;?i<re.result.length;?i++)
????????????????????????{
????????????????????????????this.txtUsers.text?+=?re.result[i].toString()?+?",?";
????????????????????????}
????????????????????????break;
????????????????}
????????????} ????在 mx:Button （GetArray）?標(biāo)簽中添加屬性 click="sampleRemoteObject.GetArray()"

????運行Flex程序，在瀏覽器中查看效果　

（二）Dictionary（http://xingfustar.cnblogs.com/)

1、.NET服務(wù)器端程序（http://xingfustar.cnblogs.com/)

????接下來我們做個Dictionary的例子，假設(shè)上例中，我們不光要獲取用戶姓名，而且我們還要得到他對應(yīng)的年齡，我們使用Dictionary。修改代碼，添加如下方法：
????????public?Dictionary<String,?Int32>?GetDictionary()
????????{
????????????Dictionary<String,?Int32>?age?=?new?Dictionary<string,?int>();
????????????age.Add("張三",?23);
????????????age.Add("李四",?24);
????????????age.Add("王五",?22);
????????????return?age;
????????}
2、Flex客戶端程序（http://xingfustar.cnblogs.com/)

????在 Design 模式下添加，添加六個 Text文本控件，屬性分別為 id = txtZhangSan，txt = ""; id = txtLiSi，txt = ""; id = txtWangWu，txt = ""; txt = "張三:"; txt = "李四:"; txt = "王五:"
????添加一個 Button控件，id為btnGetDictionary，Label屬性為?GetDictionary
????
????在 Source 模式下, 修改　mx:RemoteObject 標(biāo)簽，添加　
????<mx:method name="GetDictionary" result="RemoteResult(event)" fault="RemoteFault(event)"/>?
????修改腳本中 RemoteResult 方法，增加一個Case條件，代碼如下
????????????public?function?RemoteResult(re:ResultEvent):void
????????????{?
????????????????switch(re.currentTarget.name)
????????????????{
????????????????????case?"HelloWord":
????????????????????????var?str:String?=?re.result?as?String;
????????????????????????this.txtHelloWord.text?=?str;
????????????????????????break;
????????????????????case?"SayHello":
????????????????????????str?=?re.result?as?String;
????????????????????????this.txtSayHello.text?=?str;
????????????????????????break;
????????????????????case?"GetUsers":
????????????????????????for(var?i:int=0;?i<re.result.length;?i++)
????????????????????????{
????????????????????????????this.txtUsers.text?+=?re.result[i].toString()?+?",?";
????????????????????????}
????????????????????????break;
????????????????????case?"GetDictionary":
????????????????????????this.txtZhangSan.text?=?re.result["張三"];
????????????????????????this.txtLiSi.text?=?re.result["李四"];
????????????????????????this.txtWangWu.text?=?re.result["王五"];
????????????????????????break;
????????????????}
????????????} ????在 mx:Button （GetDictionary）?標(biāo)簽中添加屬性 click="sampleRemoteObject.GetDictionary()"

????運行Flex程序，在瀏覽器中查看效果　

（三）HashTable（http://xingfustar.cnblogs.com/)

1、.NET服務(wù)器端程序（http://xingfustar.cnblogs.com/)

????我們將上例中的Dictionary類型改成HashTable類型，代碼如下：
????????public?Hashtable?GetHashTable()
????????{
????????????Hashtable?hash?=?new?Hashtable();
????????????hash.Add("張三",?23);
????????????hash.Add("李四",?24);
????????????hash.Add("王五",?22);
????????????return?hash;
????????}
2、Flex客戶端程序（http://xingfustar.cnblogs.com/)

????借用下上例內(nèi)容，在 Design 模式下添加一個 Button控件，id為btnGetHashTable，Label屬性為?GetHashTable
????
????在 Source 模式下, 修改　mx:RemoteObject 標(biāo)簽，添加　
????<mx:method name="GetHashTable" result="RemoteResult(event)" fault="RemoteFault(event)"/>?
????修改腳本中 RemoteResult 方法，只需在上例? case "GetDictionary": 下一行加上 case "GetHashTable": 即可。
????????????????????case?"GetDictionary":
????????????????????case?"GetHashTable":
????????????????????????this.txtZhangSan.text?=?re.result["張三"];
????????????????????????this.txtLiSi.text?=?re.result["李四"];
????????????????????????this.txtWangWu.text?=?re.result["王五"];
????????????????????????break;

????在 mx:Button （GetHashTable）?標(biāo)簽中添加屬性 click="sampleRemoteObject.GetHashTable()"

????運行Flex程序，在瀏覽器中查看效果

本節(jié)內(nèi)容到此結(jié)束，其實本節(jié)的例子都差不多，相信講到這里，看過文章的人對Remoting通訊有了大概的了解，只要熟悉AS3語言，以上這些都不困難，關(guān)于這個通訊，我計劃還有一節(jié)，主要講解自定義實體對象的傳送。

如可我的文章對您有幫助，希望在轉(zhuǎn)載時保留版權(quán)及出處，謝謝！網(wǎng)友的支持是我最大的動力！
