1.WCF 契约 ICalculator.cs
using System.ServiceModel;
namespace Contracts
{
[ServiceContract]
public interface ICalculator
{
/// <summary>
/// 加法
/// </summary>
/// <param name="x"></param>
/// <param name="y"></param>
/// <returns></returns>
[OperationContract]
[DataContractFormat(Style = OperationFormatStyle.Rpc)]
double AddDouble(double x, double y); /// <summary>
/// 加法
/// </summary>
/// <param name="num1">第一个数</param>
/// <param name="num2">第二个数</param>
/// <param name="num">结果</param>
/// <returns></returns>
[OperationContract]
[DataContractFormat(Style = OperationFormatStyle.Rpc)]
string Add(double num1, double num2, ref double num); /// <summary>
/// 减法
/// </summary>
/// <param name="num1">第一个数</param>
/// <param name="num2">第二个数</param>
/// <param name="num">结果</param>
/// <returns></returns>
[OperationContract]
[DataContractFormat(Style = OperationFormatStyle.Rpc)]
string Reduce(double num1, double num2, ref double num); /// <summary>
/// 乘法
/// </summary>
/// <param name="num1">第一个数</param>
/// <param name="num2">第二个数</param>
/// <param name="num">结果</param>
/// <returns></returns>
[OperationContract]
[DataContractFormat(Style = OperationFormatStyle.Rpc)]
string Multiplication(double num1, double num2, ref double num); /// <summary>
/// 除法
/// </summary>
/// <param name="num1">第一个数</param>
/// <param name="num2">第二个数</param>
/// <param name="num">结果</param>
/// <returns></returns>
[OperationContract]
[DataContractFormat(Style = OperationFormatStyle.Rpc)]
string Division(double num1, double num2, ref double num); } }
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
using System;
using System.Collections.Generic;
using System.Text;
using Contracts; namespace Services
{
public class CalculatorService : ICalculator
{
/// <summary>
/// 加法
/// </summary>
/// <param name="x"></param>
/// <param name="y"></param>
/// <returns></returns>
public double AddDouble(double x, double y)
{
return x + y;
} /// <summary>
/// 加法
/// </summary>
/// <param name="num1">第一个数</param>
/// <param name="num2">第二个数</param>
/// <param name="num">结果</param>
/// <returns></returns>
///
public string Add(double num1, double num2, ref double num)
{
try
{
num = num1 + num2;
return "";
}
catch (Exception ex)
{
return ex.ToString();
}
} /// <summary>
/// 减法
/// </summary>
/// <param name="num1">第一个数</param>
/// <param name="num2">第二个数</param>
/// <param name="num">结果</param>
/// <returns></returns>
public string Reduce(double num1, double num2, ref double num)
{
try
{
num = num1 - num2;
return "";
}
catch (Exception ex)
{
return ex.ToString();
}
} /// <summary>
/// 乘法
/// </summary>
/// <param name="num1">第一个数</param>
/// <param name="num2">第二个数</param>
/// <param name="num">结果</param>
/// <returns></returns>
public string Multiplication(double num1, double num2, ref double num)
{
try
{
num = num1 * num2;
return "";
}
catch (Exception ex)
{
return ex.ToString();
}
} /// <summary>
/// 除法
/// </summary>
/// <param name="num1">第一个数</param>
/// <param name="num2">第二个数</param>
/// <param name="num">结果</param>
/// <returns></returns>
public string Division(double num1, double num2, ref double num)
{
try
{
num = num1 / num2;
return "";
}
catch (Exception ex)
{
return ex.ToString();
}
} }
}
3.IIS 创建文件CalculatorService.svc
<%@ServiceHost Service="Services.CalculatorService"%>
4.IIS 寄宿服务配置，基于basicHttpBinding绑定 Web.config
<?xml version="1.0"?>
<configuration>
<system.serviceModel>
<behaviors>
<serviceBehaviors>
<behavior name="CalculatorBehavior">
<serviceMetadata httpGetEnabled="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" />
<services>
<service behaviorConfiguration="CalculatorBehavior" name="Services.CalculatorService">
<endpoint address="" binding="basicHttpBinding" bindingConfiguration=""
contract="Contracts.ICalculator" />
<host>
<baseAddresses>
<add baseAddress="http://192.168.1.2:8080/CalculatorService.svc" />
</baseAddresses>
</host>
</service>
</services>
</system.serviceModel>
<system.web>
<compilation debug="true"/>
</system.web>
</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
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<EditText
android:id="@+id/txtPhoneNo"
android:layout_width="304.0dp"
android:phoneNumber="true"
android:hint="请输入第一个数"
android:layout_height="wrap_content"
android:layout_marginTop="5px"
android:layout_marginLeft="5px" />
<EditText
android:id="@+id/txtSMS"
android:layout_width="313.3dp"
android:layout_height="40.0dp"
android:phoneNumber="true"
android:gravity="top"
android:hint="请输入第二个数"
android:layout_below="@id/txtPhoneNo" />
<Button
android:id="@+id/btnadd"
android:text="加"
android:layout_width="69dp"
android:layout_height="wrap_content"
android:layout_below="@id/txtSMS" />
<Button
android:id="@+id/btnjian"
android:text="减"
android:layout_width="69dp"
android:layout_height="wrap_content"

<Button
android:id="@+id/btncheng"
android:text="乘"
android:layout_width="69dp"
android:layout_height="wrap_content"
android:layout_below="@id/txtSMS"
android:layout_toRightOf="@id/btnjian" />
<Button
android:id="@+id/btnchu"
android:text="除"
android:layout_width="69dp"
android:layout_height="wrap_content"
android:layout_below="@id/txtSMS"
android:layout_toRightOf="@id/btncheng" />
<EditText
android:id="@+id/txtjieguo"
android:layout_width="fill_parent"
android:layout_height="40.7dp"
android:gravity="top"
android:hint=""
android:layout_below="@id/btnchu" />
</RelativeLayout>
