Question

我有一个带有WCF Web服务的Silverlight应用程序。我在godaddy上托管我的数据库，并允许远程连接到数据库。当我运行我的项目，连接到远程数据库时，内容按原样加载。但是，在部署应用程序时，由于某种原因，Web服务未正确执行。它是连接到同一数据库的相同代码，但我什么都没得到。

我能够很好地浏览我的远程svc文件（访问mysite.com/mywebservice.svc）。

我可以使用以下代码从我的asp页面（而不是Web服务）获取部分数据：

    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
        {
            string myConnectionString = ConfigurationManager.ConnectionStrings["SilverlightWebConnectionString"].ConnectionString;

            using (System.Data.SqlClient.SqlConnection con = new System.Data.SqlClient.SqlConnection(myConnectionString))
            {
                using (System.Data.SqlClient.SqlCommand cmd = new System.Data.SqlClient.SqlCommand())
                {
                    cmd.CommandText = "SELECT htmlTitle FROM HtmlAttributes WHERE pageName='Home'";
                    cmd.Connection = con;

                    con.Open();

                    TitleText.Text = Convert.ToString(cmd.ExecuteScalar());

                    cmd.CommandText = "SELECT htmlDescription FROM HtmlAttributes WHERE pageName='Home'";

                    string description = Convert.ToString(cmd.ExecuteScalar());
                    DescriptionMetaText.Text = string.Format("<meta name=\"description\" content=\"{0}\" />", description);

                    con.Close();
                }
            }
        }
    }

因此，我知道这不是数据库或连接字符串的问题。我唯一的猜测是我的web.config文件中有一个属性，我没有正确设置。

以下是web.config文件的代码：

    <configuration>
      <system.web>
        <compilation debug="true" targetFramework="4.0" />
      </system.web>
      <connectionStrings>
        <add name="SilverlightWebConnectionString" connectionString="Data Source=mySource; Initial Catalog=myCatalog; User ID=myId; Password='myPassword';" providerName="System.Data.SqlClient" />
      </connectionStrings>
      <system.serviceModel>
        <behaviors>
          <serviceBehaviors>
            <behavior name="">
              <serviceMetadata httpGetEnabled="true" />
              <serviceDebug includeExceptionDetailInFaults="false" />
            </behavior>
          </serviceBehaviors>
        </behaviors>

<bindings>
  <customBinding>
    <binding name="MySilverlightWebsite.Web.MyWebService.customBinding0">
      <!--<binaryMessageEncoding />-->
      <textMessageEncoding>
        <readerQuotas maxStringContentLength="2147483647"/>
      </textMessageEncoding>
      <httpTransport />
    </binding>
  </customBinding>
</bindings>

<services>

  <service name="MySilverlightWebsite.Web.MyWebService">
    <endpoint address="" binding="customBinding" bindingConfiguration="MySilverlightWebsite.Web.MyWebService.customBinding0" contract="MySilverlightWebsite.Web.MyWebService" />
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
  </service>

</services>

<serviceHostingEnvironment minFreeMemoryPercentageToActivateService="0" aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />

仅在部署时Silverlight WCF Web服务连接问题
