1.WCF 契约 ICalculator.cs

注意:
在客户端添加Web引用时为避免额外的布尔值参数被使用,确保代理客户端强制执行时使用的RPC风格的编码,这是SOAP 1.1规范的一部分。

2. 服务实现 CalculatorService.cs
1 using System; 2 using System.Collections.Generic; 3 using System.Text; 4 using Contracts; 5 6 namespace Services 7 { 8 public class CalculatorService : ICalculator 9 { 10 /// <summary> 11 /// 加法 12 /// </summary> 13 /// <param name="x"></param> 14 /// <param name="y"></param> 15 /// <returns></returns> 16 public double AddDouble(double x, double y) 17 { 18 return x + y; 19 } 20 21 /// <summary> 22 /// 加法 23 /// </summary> 24 /// <param name="num1">第一个数</param> 25 /// <param name="num2">第二个数</param> 26 /// <param name="num">结果</param> 27 /// <returns></returns> 28 /// 29 public string Add(double num1, double num2, ref double num) 30 { 31 try 32 { 33 num = num1 + num2; 34 return "1"; 35 } 36 catch (Exception ex) 37 { 38 return ex.ToString(); 39 } 40 } 41 42 /// <summary> 43 /// 减法 44 /// </summary> 45 /// <param name="num1">第一个数</param> 46 /// <param name="num2">第二个数</param> 47 /// <param name="num">结果</param> 48 /// <returns></returns> 49 public string Reduce(double num1, double num2, ref double num) 50 { 51 try 52 { 53 num = num1 - num2; 54 return "1"; 55 } 56 catch (Exception ex) 57 { 58 return ex.ToString(); 59 } 60 } 61 62 63 /// <summary> 64 /// 乘法 65 /// </summary> 66 /// <param name="num1">第一个数</param> 67 /// <param name="num2">第二个数</param> 68 /// <param name="num">结果</param> 69 /// <returns></returns> 70 public string Multiplication(double num1, double num2, ref double num) 71 { 72 try 73 { 74 num = num1 * num2; 75 return "1"; 76 } 77 catch (Exception ex) 78 { 79 return ex.ToString(); 80 } 81 } 82 83 /// <summary> 84 /// 除法 85 /// </summary> 86 /// <param name="num1">第一个数</param> 87 /// <param name="num2">第二个数</param> 88 /// <param name="num">结果</param> 89 /// <returns></returns> 90 public string Division(double num1, double num2, ref double num) 91 { 92 try 93 { 94 num = num1 / num2; 95 return "1"; 96 } 97 catch (Exception ex) 98 { 99 return ex.ToString(); 100 } 101 } 102 103 } 104 }
3.IIS 创建文件CalculatorService.svc
1 <%@ServiceHost Service="Services.CalculatorService"%>
4.IIS 寄宿服务配置,基于basicHttpBinding绑定 Web.config
1 <?xml version="1.0"?> 2 <configuration> 3 <system.serviceModel> 4 <behaviors> 5 <serviceBehaviors> 6 <behavior name="CalculatorBehavior"> 7 <serviceMetadata httpGetEnabled="true"/> 8 </behavior> 9 </serviceBehaviors> 10 </behaviors> 11 <serviceHostingEnvironment multipleSiteBindingsEnabled="true" /> 12 <services> 13 <service behaviorConfiguration="CalculatorBehavior" name="Services.CalculatorService"> 14 <endpoint address="" binding="basicHttpBinding" bindingConfiguration="" 15 contract="Contracts.ICalculator" /> 16 <host> 17 <baseAddresses> 18 <add baseAddress="http://192.168.1.2:8080/CalculatorService.svc" /> 19 </baseAddresses> 20 </host> 21 </service> 22 </services> 23 </system.serviceModel> 24 <system.web> 25 <compilation debug="true"/> 26 </system.web> 27 </configuration>
注意:为了保证 soap:address location 和wsdl:import location 显示和url里面的ip或者域名是一致请使用:<serviceHostingEnvironment multipleSiteBindingsEnabled="true" /> ,multipleSiteBindingsEnabled 是.net framework 4里面支持的特性,如果版本低于4,例如3.5 那么就要根据IIS binding来设置baseAddress.
5.Main.axml 视图
1 <?xml version="1.0" encoding="utf-8"?> 2 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 3 android:layout_width="fill_parent" 4 android:layout_height="fill_parent"> 5 <EditText 6 android:id="@+id/txtPhoneNo" 7 android:layout_width="304.0dp" 8 android:phoneNumber="true" 9 android:hint="请输入第一个数" 10 android:layout_height="wrap_content" 11 android:layout_marginTop="5px" 12 android:layout_marginLeft="5px" /> 13 <EditText 14 android:id="@+id/txtSMS" 15 android:layout_width="313.3dp" 16 android:layout_height="40.0dp" 17 android:phoneNumber="true" 18 android:gravity="top" 19 android:hint="请输入第二个数" 20 android:layout_below="@id/txtPhoneNo" /> 21 <Button 22 android:id="@+id/btnadd" 23 android:text="加" 24 android:layout_width="69dp" 25 android:layout_height="wrap_content" 26 android:layout_below="@id/txtSMS" /> 27 <Button 28 android:id="@+id/btnjian" 29 android:text="减" 30 android:layout_width="69dp" 31 android:layout_height="wrap_content" 32 android:layout_below="@id/txtSMS" 33 android:layout_toRightOf="@id/btnadd" /> 34 <Button 35 android:id="@+id/btncheng" 36 android:text="乘" 37 android:layout_width="69dp" 38 android:layout_height="wrap_content" 39 android:layout_below="@id/txtSMS" 40 android:layout_toRightOf="@id/btnjian" /> 41 <Button 42 android:id="@+id/btnchu" 43 android:text="除" 44 android:layout_width="69dp" 45 android:layout_height="wrap_content" 46 android:layout_below="@id/txtSMS" 47 android:layout_toRightOf="@id/btncheng" /> 48 <EditText 49 android:id="@+id/txtjieguo" 50 android:layout_width="fill_parent" 51 android:layout_height="40.7dp" 52 android:gravity="top" 53 android:hint="" 54 android:layout_below="@id/btnchu" /> 55 </RelativeLayout>
