运行报错：string subscript out of range

楼主，可以试试下面的代码，只供参考：

#include <iostream>
#include <fstream>
#include <cstdlib>
#include <string>
int main()
{
	using namespace std;
	ofstream outFile;
	outFile.open("可修复装备.txt");
	ifstream inFile;
	inFile.open("Commodity.ini");
	if (!inFile.is_open())
	{
		cout << "打开文件\"Commodity.ini\"失败" << endl;
		cin.get();
		exit(EXIT_FAILURE);
	}

	string sz;
	string name;
	string price;
	getline(inFile, sz);
	while (sz != "")
	{
		if (sz[9] == 'n' && sz[10] == 'a' && sz[11] == 'm' && sz[12] == 'e')
		{
			name = sz;
			while (getline(inFile, sz))
			{
				if (sz[0] == 'r' && sz[1] == 'e' && sz[2] == 's' && sz[3] == 't' && sz[4] == 'o' && sz[5] == 'r')
				{
					if (sz[14] != '0')
					{
						price = sz;
						outFile << name << endl << price << endl;
					}
					break;
				}
			}
		}
		getline(inFile, sz);
	}
	cout << "Done." << endl;
	cin.get();
	return 0;
}

还有注意，你的ini文件每行之间不应该有空行出现,应该入下面的显示：

requestpayforcost = 10000
rebate = 100
vnetprice = -1
vnetdaypaylimit = 100
[commodity.3]
commodityid = 28076
commodityname = 胖小丁
commoditytype = 1283
itemcount = 1
item.1.id = 28076
item.1.num = 1
item.1.availperiod = -1
qprice = -1
qqgameprice = -1
qqtangprice = -1
qqpointprice = -1
restorprice = 0
saledatelimit = 0
memberrebate = 90
attribute = 0
requestpayforcost = 10000
rebate = 100
vnetprice = -1
vnetdaypaylimit = 100
[commodity.4]
commodityid = 28074
commodityname = 宝石小鬼
commoditytype = 1283
itemcount = 1
item.1.id = 28074
item.1.num = 1
item.1.availperiod = -1
qprice = -1
qqgameprice = -1
qqtangprice = -1
qqpointprice = -1
restorprice = 1
saledatelimit = 0
memberrebate = 90
attribute = 0
requestpayforcost = 10000
rebate = 100
vnetprice = -1
vnetdaypaylimit = 100

在最后一行vnetdaypaylimit = 100下面应该有一行空的。这些在windows vs2013是可以的。

假如ini文件有空行呢 该怎么改...

为啥不用xml，这ini看起来好累
