配置文件web.config:

  <connectionStrings>
	  <add name="eport" connectionString="Data Source=39.106.56.128;Initial Catalog=eport;User ID=root;Password=abc@123654;Charset=gbk"   />
  </connectionStrings>

public static string connectionString = ConfigurationManager.ConnectionStrings["eport"].ToString();
