在慧都之前的幾篇文章中也提到了，報表開發(fā)工具FastReport .NET最新的WCF服務(wù)庫FastReport.Service.dll非常的強大而且易用，今天我們將介紹基于其創(chuàng)建托管在windows服務(wù)中的WCF服務(wù)的方法。

1、打開Visual Studio并創(chuàng)建一個項目WindowsService（在在線模板中）。

2、用設(shè)計器打開Service1.cs

3、修改服務(wù)名稱，例子中用的是“ReportService”。

4、右鍵單擊窗口，選擇“添加安裝程序”。

5、修改serviceInstaller1控件的屬性，設(shè)置DisplayName。

6、在serviceProcessInstaller1屬性中選擇賬戶類型為LocalSystem

7、在項目中添加引用System.ServiceModel和FastReport.Service.dll。

8、創(chuàng)建應(yīng)用程序配置文件

9、在配置文件中添加以下文本：

<?xml version="1.0"?>
<configuration>
 <appSettings>
 <!-- path to folder with reports -->
 <add key="FastReport.ReportsPath" value="C:\Program files\FastReports\FastReport.Net\Demos\WCF" />
 <!-- name of connection string for reports -->
 <add key="FastReport.ConnectionStringName" value="FastReportDemo" />
 <!-- Comma-separated list of available formats PDF,DOCX,XLSX,PPTX,RTF,ODS,ODT,MHT,CSV,DBF,XML,TXT,FPX. 
 You can delete any or change order in this list. -->
 <add key="FastReport.Gear" value="PDF,DOCX,XLSX,PPTX,RTF,ODS,ODT,MHT,CSV,DBF,XML,TXT,FPX" />
 </appSettings>
 <connectionStrings>
 <add name="FastReportDemo" connectionString="XsdFile=;XmlFile=C:\Program Files\FastReports\FastReport.Net\Demos\Reports\nwind.xml"/>
 </connectionStrings>
 <system.web>
 <compilation debug="true" />
 <membership defaultProvider="ClientAuthenticationMembershipProvider">
 <providers>
 <add name="ClientAuthenticationMembershipProvider" type="System.Web.ClientServices.Providers.ClientFormsAuthenticationMembershipProvider, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" serviceUri="" />
 </providers>
 </membership>
 <roleManager defaultProvider="ClientRoleProvider" enabled="true">
 <providers>
 <add name="ClientRoleProvider" type="System.Web.ClientServices.Providers.ClientRoleProvider, System.Web.Extensions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" serviceUri="" cacheTimeout="86400" />
 </providers>
 </roleManager>
 </system.web>
 <!-- When deploying the service library project, the content of the config file must be added to the host's 
 app.config file. System.Configuration does not support config files for libraries. -->
 <system.serviceModel>
 <services>
 <service behaviorConfiguration="FastReportServiceBehavior" name="FastReport.Service.ReportService">
 <endpoint address="" binding="wsHttpBinding" contract="FastReport.Service.IFastReportService">
 <identity>
 <dns value="localhost" />
 </identity>
 </endpoint>
 <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
 <host>
 <baseAddresses>
 <add baseAddress="//localhost:8732/FastReportService/" />
 </baseAddresses>
 </host>
 </service>
 </services>
 <behaviors>
 <serviceBehaviors>
 <behavior name="FastReportServiceBehavior">
 <serviceMetadata httpGetEnabled="True" />
 <serviceDebug includeExceptionDetailInFaults="True" />
 </behavior>
 </serviceBehaviors>
 </behaviors>
 <bindings>
 <basicHttpBinding>
 <binding messageEncoding="Mtom"
 closeTimeout="00:02:00" openTimeout="00:02:00"
 receiveTimeout="00:10:00" sendTimeout="00:02:00"
 maxReceivedMessageSize="67108864" maxBufferSize="65536"
 transferMode="Streamed">
 <security mode="None">
 <transport clientCredentialType="None" />
 </security>
 </binding>
 </basicHttpBinding>
 </bindings>
 </system.serviceModel>
 <startup>
 <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0" />
 </startup>
</configuration>

10、編輯Service1.cs，添加以下行：

using System.ServiceModel;

11、修改服務(wù)類：

public partial class ReportService : ServiceBase
 {
 ServiceHost reportHost;
 
 public ReportService()
 {
 InitializeComponent();
 }
 
 protected override void OnStart(string[] args)
 {
 if (reportHost != null)
 reportHost.Close();
 reportHost = new ServiceHost(typeof(FastReport.Service.ReportService));
 reportHost.Open();
 }
 
 protected override void OnStop()
 {
 reportHost.Close();
 reportHost = null;
 }
 }

12、接下來就可以進行開發(fā)編碼了。
