ini 파일 읽고 쓰기 본문
1. dll 활용
// dll 선언
[DllImport("kernel32.dll")]
private static extern uint GetPrivateProfileString(string section, string key, string defaultValue, StringBuilder returnedString, uint size, string filePath);
[DllImport("kernel32.dll")]
private static extern bool WritePrivateProfileString(string section, string key, string value, string filePath);
// 사용
// ini파일 구성
// [section]
// key : value
string Section = "테스트 Section";
string Key= "테스트 Key";
string Value = "테스트 Value";
stringBuilder sb = new StringBuilder { Capacity = 100 };
string filePath = @"C:\Settings.ini";
// 읽기
GetPrivateProfileString(section, key, value, sb, (uint)sb.Capacity, filePath);
// 쓰기
WritePrivateProfileString( section , key , Value , FilePath);
2. ini.cs 활용
// dll 활용해서 첫 ini 생성 시 바로 쓰기가 안되는 현상 때문에 default 값 넣을때만 사용.
