为什么\\字符正在我的@串翻倍？ [英] Why is \ character being doubled in my @ string?

问题描述

var phone = @"^\+(?:[0-9] ?){6,14}[0-9]$";

手机也就那么等于 ^ \\\\ +（？：？[0-9]）{} 6,14 [0-9] $

我想（我发现的例子似乎显示）@字符意味着要离开我的字符串我怎么有它。为什么会加倍\\以及如何阻止它？

I thought (and the examples I found seem to show) the @ character meant to leave my string how I have it. Why is it doubling the \ and how do I stop it?

推荐答案

在Visual Studio调试器的显示的它，好像它加倍，因为在C＃\\将precede转义序列。别担心 - 你的字符串是不变的。

The visual studio debugger will show it as if it were doubled, since in C# a \ would precede an escape sequence. Don't worry - your string is unchanged.
