[转]silverlight向wcf传递大于8192字节(8k)的字符串

默认情况下，silverlight在调用wcf时，如果传递的参数长度大于8192字节，即8k，会提示Not Found错误。
解决方法如下：
1、wcf服务端修改web.config 如下:
view sourceprint?
01 <?xml version="1.0"?>
02   
03 <!--

06   -->
07   
08 <configuration>
09     <system.web>
10         <compilation debug="true" targetFramework="4.0" />
11     </system.web>
12   <system.serviceModel>
13     <behaviors>
14       <serviceBehaviors>
15         <!--注:此处的name值要跟下面的behaviorConfiguration值对应-->
16         <behavior name="A">
17           <serviceMetadata httpGetEnabled="true"/>
18           <serviceDebug includeExceptionDetailInFaults="false"/>
19           <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
20         </behavior>
21       </serviceBehaviors>
22     </behaviors>
23     <services>
24       <!--注1:此处的behaviorConfiguration值要跟上面的name值对应-->
25       <!--注2:此处的name值不能随便修改，命名格式为：完全命名空间+类名 -->
26       <service behaviorConfiguration="A" name="WCF_SL_8192.Web.WCF.HelloWorld">
27         <!--注1:此处的contract值不能随便修改，命名格式为：完全命名空间+类名 -->
28         <!--注2:此处的bindingConfiguration值要与下面 binding name中的name值对应-->
29         <endpoint address="" bindingConfiguration="BBB" binding="basicHttpBinding" contract="WCF_SL_8192.Web.WCF.HelloWorld"/>      
30       </service>
31     </services>
32     <bindings>
33       <basicHttpBinding>
34         <binding name="BBB" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
35           <!--name=随意命名，但要与上面的bindingConfiguration="BBB"对应 -->
36           <readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647"/>
37           <security mode="None"></security>
38         </binding>
39       </basicHttpBinding>
40     </bindings>
41   </system.serviceModel>
42 </configuration>
附：wcf的代码
view sourceprint?
01 using System.ServiceModel;
02   
03 namespace WCF_SL_8192.Web.WCF
04 {
05     [ServiceContract]
06     public class HelloWorld
07     {
08         [OperationContract]
09         public int Test(string msg)
10         {
11             return msg.Length;
12         }
13     }
14 }
2、SL端修改ClientConfig如下：
view sourceprint?
01 <configuration>
02   <system.serviceModel>
03     <bindings>
04       <basicHttpBinding>
05         <binding name="BasicHttpBinding_HelloWorld" maxBufferSize="2147483647"
06              maxReceivedMessageSize="2147483647">
07           <security mode="None" />
08         </binding>
09       </basicHttpBinding>
10       <!--下面这个节点是关键-->
11       <customBinding>
12         <binding name="BasicHttpBinding_HelloWorld">
13           <textMessageEncoding messageVersion="Default" writeEncoding="utf-8" />
14           <httpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" />
15         </binding>
16       </customBinding>
17     </bindings>
18     <client>
19       <endpoint address="http://localhost:1588/WCF/HelloWorld.svc"
20           binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_HelloWorld"
21           contract="WCF.HelloWorld" name="BasicHttpBinding_HelloWorld" />
22     </client>
23   </system.serviceModel>
24 </configuration>
附:SL的调用代码
view sourceprint?
01 using System;
02 using System.Windows;
03 using System.Windows.Controls;
04 using WCF_SL_8192.WCF;
05   
06 namespace WCF_SL_8192
07 {
08     public partial class MainPage : UserControl
09     {
10         public MainPage()
11         {
12             InitializeComponent();
13   
14             this.Loaded += new RoutedEventHandler(MainPage_Loaded);
15   
16   
17         }
18   
19         void MainPage_Loaded(object sender, RoutedEventArgs e)
20         {
21             HelloWorldClient client = new HelloWorldClient();           
22             client.TestCompleted += new EventHandler<TestCompletedEventArgs>(client_TestCompleted);
23             System.Text.StringBuilder sb = new System.Text.StringBuilder();
24             for (int i = 0; i < 100000; i++)
25             {
26                 sb.Append("A");
27             }
28             client.TestAsync(sb.ToString());
29         }
30   
31         void client_TestCompleted(object sender, TestCompletedEventArgs e)
32         {
33             MessageBox.Show(e.Result.ToString());
34         }
35     }
36 }
