如何在TypeScript中实现Regexp？

我的例子:

var trigger = "2"
var regex = new RegExp('^[1-9]\d{0,2}$', trigger); // where I have exeption in Chrome console

我需要从我启用Windows身份验证web.config,而不在IIS中设置它.

我有以下元素web.config:

  authentication mode="Windows
  identity impersonate="true 

但是Windows身份验证不起作用.我该如何解决这个问题？

我正在寻找一个只验证正数(整数)的正则表达式:

0-999,第一个数字不是0.

我的例子不起作用:

string pattern = @"^\d+$";

如何确定正数模式？

我有枚举:

public enum MonthsOfTheYear
{
    January = 1,
    February = 2,
    March = 4,
    April = 8,
    May = 16,
    June = 32,
    July = 64,
    August = 128,
    September = 256,
    October = 512,
    November = 1024,
    December = 2048,
    AllMonths = 4095,
}  

和Datime.Now.Month.

例如,如果month的值为5,则等于"May",我如何与月枚举进行比较？这个例子不起作用:if(!monthsOfYear.Any(x => x.Code.Equals((MonthsOfTheYear)(1 <<(currentDateTime.Month - 1)))
