c# – 如何获取配置文件的ConnectionString名称

我可以从配置文件中读取connectionstring / s但是我需要获取与连接字符串相关联的元素名称

例

<connectionStrings>
<add 
  name="LocalsqlServer" 
  connectionString="data source=.\sqlEXPRESS;Integrated Security=sspI;AttachDBFilename=|DataDirectory|aspnetdb.mdf;User Instance=true" 
  providerName="System.Data.sqlClient"   />
 </connectionStrings>

我需要从connectionString中获取LocalsqlServer

解决方法

根据 documentation,它应该像这样工作：

ConnectionStringSettingsCollection connections = ConfigurationManager.ConnectionStrings;

if (connections.Count != 0)
{
    foreach (ConnectionStringSettings connection in connections)
    {
        string name = connection.Name;
    }
}
