第三個工具類：IniReader

就是讀ini配置檔案的一個工具類，很簡單，就是封裝了一下boost庫的ptree

IniReader.h

#ifndef __IniReader_h__
#define __IniReader_h__

#include <string>
#include <boost/property_tree/ptree.hpp>

namespace common{
	namespace tool{

		class IniReader
		{
		public:
			IniReader();
			~IniReader();

			bool InitIni(const std::string& path);

			bool GetValue(const std::string& root, const std::string& key, std::string& value);

			bool GetValue(const std::string& root, const std::string& key, unsigned int& value);

		private:
			bool m_IsInit;
			boost::property_tree::ptree m_Pt;
		};

	}
}

#endif
 

#include "IniReader.h"

#include <boost/property_tree/ini_parser.hpp>

namespace common{
	namespace tool{

		IniReader::IniReader()
		{
			m_IsInit = false;
		}

		IniReader::~IniReader()
		{

		}

		bool IniReader::InitIni(const std::string& path)
		{
			try
			{

			return m_IsInit;
		}

		bool IniReader::GetValue(const std::string& root, const std::string& key, std::string& value)
		{
			if (m_IsInit)
			{
				try
				{
					std::string strTemp(root + "." + key);
					value = m_Pt.get<std::string>(strTemp);
