未核对的转义序列

本文介绍了未核对的转义序列的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

好吧，从这里开始是代码

Well, to start with here is the code

config.Set("Silk", txt_silkdir.Text+"\silkroad.exe")

导致UNRECONIZED ESCAPE SEQUENCE错误的原因是"\ silkroad.exe"之类的部分 问题是我需要文件名带有\开头，因为我不知道如何在文件夹中添加尾随\\ BrowserDialog selectePath

And the thing cause the UNRECONIZED ESCAPE SEQUENCE error is the part were it is like "\silkroad.exe" The thing is i need it to have the \ infront of the filename because i do not know how to add a trailing \ to the folderBrowserDialog selectePath Any help would be apreciated.

推荐答案

使用@或\转义序列字符. config.Set("Silk", txt_silkdir.Text+ @"\silkroad.exe") 或 config.Set("Silk", txt_silkdir.Text+ "\\silkroad.exe") Use the @ or \ escape sequence character. config.Set("Silk", txt_silkdir.Text+ @"\silkroad.exe") OR config.Set("Silk", txt_silkdir.Text+ "\\silkroad.exe")

在普通的C#字符串中，"\"字符引入了转义序列-一种将字符放入您不能键入的字符串中的方法(例如，换行符:"\ n")或字符串语法的一部分(ee双引号"\"''). 有两种解决方法: 1)在字符串前面加上一个"@"字符，在这种情况下，"\"将不再是转义序列介绍符. In a normal C# string, the ''\'' character introduces an Escape Sequence - a way of getting characters into a string that you either can''t type (e.g. Newline: ''\n'') or which are part of the string syntax (e.e. double quotes ''\"''). There are two ways around this: 1) Prefix your string with a ''@'' charcater, in which case ''\'' ceases to be an escape sequence introducer. config.Set("Silk", txt_silkdir.Text+@"\silkroad.exe")

或 2)使用转义序列"\\"代替，它会在字符串中产生单个"\".

or 2) Use the escape squence ''\\'' instead which produces a single ''\'' as part of your string.

config.Set("Silk", txt_silkdir.Text+"\\silkroad.exe")
