我想获得一个logFilePath值,我将硬编码提供给appSettings.我试图达到关键价值

System.Configuration.Configuration rootWebConfig1 = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration(null);
System.Configuration.KeyValueConfigurationElement customSetting = rootWebConfig1.AppSettings.Settings["azureLogUrl"];
string pathValue =  customSetting.Value;

但我得到null引用异常.如何从web.config文件中获取值？
