打开Visual Studio，创建一个项目WindowsService。

打开Service1.cs的设计器

右击窗口，在弹出的窗口中选择 “Add Installer”。

在项目中添加对System.ServiceModel和FastReport.Service.dll的引用。

将以下文字复制到新的app.config文件中：

<ml version="1.0"gt;<configuration><appSettings><!-- path to folder with reports --><add key="FastReport.ReportsPath" value="C:ProgramfilesFastReportsFastReport.NetDemosWCF" /><!-- 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:ProgramFilesFastReportsFastReport.NetDemosReportsnwind.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 configfile must be added to the host'sapp.config file. System.Configuration does not support config files forlibraries. --><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="http://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>

Go to the editor of Service1.cs and add the line:

using System.ServiceModel;Modify the class of service so it looks like: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;}}

你可以使用命令行实用程序InstallUtil.exe来安装服务，例如，它是.NET Framework自带的。

C:Windows/Microsoft.NET/Framework/v4.0.30319/InstallUtil.exe “C:MyProjects/WcfService1/WindowsService1/Debug/WindowsService1.exe”

你可以用命令启动服务:

net start ReportService

打开 页浏览器，查看app.config中baseAddress中设置的地址http://localhost:8732/FastReportService/。你可以把文件夹和端口改成你自己选择的。

停止和卸载服务的命令:

net stop ReportService

C:Windows/Microsoft.NET/Framework/v4.0.30319/InstallUtil.exe /u “C:MyProjects/WcfService1/WindowsService1/bin/Debug/WindowsService1.exe”

这个例子位于文件夹”DemosC#WCFWindowsService “中。
