App.Config XML읽고 쓰기..

App.Config XML파일을 읽고 쓰는 간단한 함수를 하나 만들어 봤습니다..

더 좋은 정보 있으면 리플 달아 주세요…

 

 

private string AppConfigRead(string keyName)

        {

            string strReturn;

            Configuration currentConfig =

                ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

 

            if (currentConfig.AppSettings.Settings.AllKeys.Contains(keyName))

                strReturn = currentConfig.AppSettings.Settings[keyName].Value;

            else

                strReturn = ""; //키가없으면.

 

            return strReturn;

        }

 

        private bool AppConfigWrite(string keyName, string value)

        {

            Configuration currentConfig =

                ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);

 

            if (currentConfig.AppSettings.Settings.AllKeys.Contains(keyName)) //키가 있으면

                currentConfig.AppSettings.Settings[keyName].Value = value;

            else       //키가 없으면

                currentConfig.AppSettings.Settings.Add(keyName, value);

           

            currentConfig.Save();

            ConfigurationManager.RefreshSection("appSettings");   // 내용 갱신             

            return true;

        }

우선 위 함수를 사용하려면 참조 추가와 namespace 추가가 필요합니다.
1) System.configuration <- 참조 추가
2) using System.Configuration; <- 추가

그렇게 하고도.. 위의 소스에서 Contains 라는걸 찾을 수 없어서 제맘대로 수정했습니다.
정석인진 모르겠지만..돌아가니 참고하실분은 하세요.
