读配置文件出现"Configuration system failed to initialize"是什么问题啊?
配置文件是：

HTML code

<?xml version="1.0" encoding="utf-8"?><configuration>  <AppSettings>    <add key="password" value="123456" />  </AppSettings></configuration>

读取是：

C# code

public string GetAppConfig(string strKey)        {            try            {                foreach (string key in ConfigurationManager.AppSettings)                {                    if (key == strKey)                    {                        return ConfigurationManager.AppSettings[strKey];                    }                }                return null;            }            catch(System.Exception ex)            {                Console.WriteLine("{0} GetAppConfig()Exception caught.", ex);                return null;            }        }

为何foreach (string key in ConfigurationManager.AppSettings)
时总抛出异常呢？
