Question

我已经编写了一个WCF服务应用程序。生成项目时，visual studio会创建3个Web配置文件。

我已经完成了项目，到目前为止我一直在GetOpenConnection（）函数中使用硬编码连接字符串，所以我现在想将连接字符串移动到web.config文件。 / p>

以下调用返回null。 ConnectionStringSettings csSettings = ConfigurationManager.ConnectionStrings [＆＃34; PulseWcfConnectionString＆＃34;];

当我运行以下代码时，它不会返回我的web.debug.config文件中设置的字符串。

for(int idx = 0; idx < ConfigurationManager.ConnectionStrings.Count; idx++)
  Debug.WriteLine(ConfigurationManager.ConnectionStrings[idx].ConnectionString);

它返回以下2项，第二项是空字符串。我不认识第一行，也许它是默认的一行？

data source=.\SQLEXPRESS;Integrated Security=SSPI; AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true
""

我错过了什么？

我的web.debug.config包含以下应该用于本地sql server实例

<?xml version="1.0"?>

<!-- For more information on using web.config transformation visit http://go.microsoft.com/fwlink/?LinkId=125889 -->

<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">

  <connectionStrings>
    <add
      name="PulseWcfConnectionString"
      connectionString="Data Source=WIN8-CLAIRE\SQLSRVDEV2008;Initial 
    Catalog=gcll;Persist Security Info=True;Integrated Security=True"
      providerName="System.Data.SqlClient"
  />
  </connectionStrings>

</configuration>

现在我的web.release.config包含相同的内容（它明天将发布到它的目的地，所以我将更改它的详细信息）

<?xml version="1.0"?>

<!-- For more information on using web.config transformation visit http://go.microsoft.com/fwlink/?LinkId=125889 -->

<configuration xmlns:xdt="http://schemas.microsoft.com/XML-Document-Transform">

如果您使用转换文件，则需要添加转换属性，并指定要执行的操作，插入，删除，替换...

我用来将本地连接放在master web.config中，然后通过替换定义的连接字符串的属性，在Release配置中对其进行转换。

查看此文章：Web.config Transformation Syntax for Web Project Deployment Using Visual Studio

如果您想使用自己的方式，只需在xdt:Transform="Insert"节点中添加<add>。

您可以使用此网络测试工具测试您的转化：Web.config Transformation Tester
