Silverlight读取webconfig配置文件

遇到程序代码调试时可以正常读取web.config数据库连接串
System.Configuration.ConfigurationManager.ConnectionStrings["PigeonConnectionString"].ToString()

但部署到IIS上，却数据库连接失败,经过写日志跟踪发现读取的连接串为$(ReplacableToken_PigeonConnectionString-Web.config Connection String_0)
   解决方法1
  需要修改项目文件，注意是项目文件(即:D:\VS2010Pro\Pigeon.Web\Pigeon.Web.csproj 

在PropertyGroup里添加如下属性：

<AutoParameterizationWebConfigConnectionStrings>False</AutoParameterizationWebConfigConnectionStrings>

这样就会正常生成自定义的连接串

以下是截取的片段

<?xml version="1.0" encoding="utf-8"?>

<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">

  <PropertyGroup>

    <AutoParameterizationWebConfigConnectionStrings>False</AutoParameterizationWebConfigConnectionStrings>

    <Configuration Condition=" '$(Configuration)' == '' ">Debug</Configuration>

 

 

另外一种Silverlight读取网站项目中的Web.config数据库连接串的方法（VS2010)

添加一个Silverlight项目，会生成两个工程,(一个Silvelight项目，一个网站项目)

  1. 在网站项目的PA_QCReportTestPage.html和PA_QCReportTestPage.aspx中加入红色字体的内容

    <form id="form1" runat="server" style="height:100%">

    <div id="silverlightControlHost">

        <object data="data:application/x-silverlight-2," type="application/x-silverlight-2" width="100%" height="100%">

    <param name="source" value="ClientBin/PA_QCReport.xap"/>

    <param name="onError" value="onSilverlightError" />

    <param name="background" value="white" />

    <param name="minRuntimeVersion" value="4.0.50826.0" />

    <param name="autoUpgrade" value="true" />
          <param name="InitParams" value='WcfServiceAddress=<%= System.Configuration.ConfigurationManager.AppSettings["WcfServiceAddress"] %>' />
    <a href="http://go.microsoft.com/fwlink/?LinkID=149156&v=4.0.50826.0"
style="text-decoration:none">

      <img src="http://go.microsoft.com/fwlink/?LinkId=161376" alt="获取 Microsoft Silverlight"
style="border-style:none"/>

    </a>

     </object><iframe id="_sl_historyFrame" style="visibility:hidden;height:0px;width:0px;border:0px"></iframe></div>

    </form>

  2.在Silverlight项目的App.xaml.cs中加入红色字体的内容

        private void Application_Startup(object sender, StartupEventArgs e)

        {
            var slServicePath = e.InitParams["WcfServiceAddress"];

            //将读取到的WCF地址保存到资源中。

            Application.Current.Resources.Add("WcfServiceAddress", slServicePath);
            this.RootVisual = new MainPage();

        }

          //调用方法

                              servicePicture.Endpoint.Address =

                        new System.ServiceModel.EndpointAddress(Application.Current.Resources["WcfServiceAddress"]
+ "/wcfMain.svc");
