Connection String运行时初始化

Question

如何从C＃中的控制台应用程序内的远程文件初始化连接字符串：

我目前这样做是为了让AppSettings从远程位置加载：

string runtimeAppSettingsconfigfile =“c：\ Somepath \ StaticAppSettings.config”

System.Configuration.Configuration config
    = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
config.AppSettings.File = runtimeAppSettingsconfigfile;
config.Save(ConfigurationSaveMode.Modified);
ConfigurationManager.RefreshSection("appSettings");

如何为连接字符串配置文件实现相同的功能，即远程加载连接字符串文件？

编辑：

到目前为止我尝试的是：

string runtimeConnectionStringConfigfile = "c:\somepath\StaticConnectionStrings.config"
Configuration config =                          ConfigurationManager.OpenExeConfiguration(runtimeConnectionStringConfigfile);

config.Save(ConfigurationSaveMode.Modified);
ConfigurationManager.RefreshSection("connectionStrings");

Connectionstring文件示例：

<connectionStrings>
    <add name="mydb" connectionString="Data Source=PrimaryDB;Initial Catalog=test;Persist Security Info=True;User ID=testuser;Password=test; Asynchronous Processing=true" providerName="System.Data.SqlClient" />
</connectionStrings>
