Visual Studio 2010和2013中C++CLR里面枚举有何区别？

Question

我按照Ivory Horton's Beginning Visual C++2010上面说的写出来的代码为什么在2013里面运行不了？

求解。

下面代码，程序提示说：

1. 错误 1 error C2665: “System::Console::WriteLine”: 19 个重载中没有一个可以转换所有参数类型 C:\Users\浩然\Documents\Visual Studio 2013\Projects\test2_06_1\test2_06_1\test2_06_1.cpp 16 1 test2_06_1
2. 错误 2 error C2676: 二进制“+”:“Month”不定义该运算符或到预定义运算符可接收的类型的转换 C:\Users\浩然\Documents\Visual Studio 2013\Projects\test2_06_1\test2_06_1\test2_06_1.cpp 17 1 test2_06_1

#include "stdafx.h"

using namespace System;

enum class Month{January=1, Febrary, March, April, May, June, July, August, September, October, November, December};

int main(array<System::String ^> ^args)
{
	Month month = Month::January;
	int value;
	for (int i = 0; i < 12; ++i)
	{
		value = safe_cast<int>(month);
		Console::WriteLine(L"Month is {0} and value is {1}", month, value);
		month=month+Month::Febrary;
	}

    return 0;
}
