VC的Ini文件读写类

Delphi用惯了，今天写族谱管理时发现VC居然没有ini文件操作的类（可能是我无知），只好自己动手。仿照Delphi的TIniFile写的，功能如下：

bool SectionExists(CString Section);
CString ReadString(CString Section, CString Ident, CString Default);
void WriteString(CString Section, CString Ident, CString Value);
int ReadInteger(CString Section, CString Ident, int Default);
void WriteInteger(CString Section, CString Ident, int Value);
void ReadSection(CString Section, CStringArray &Strings);
void ReadSections(CStringArray &Strings);
void ReadSectionValues(CString Section, CStringArray &Strings);
void EraseSection(CString Section);
