如何从以下字符串中删除\，字符：

Hi all

"\"status\":\"ok\""

< b>我尝试了什么：



我使用下面的代码，但运行时结果是：

代码：

What I have tried:

I use following code , but when run the Result is :

"status":"ok";

but i need :
status:ok

code:

string s = arr[i].Replace("'\\'", " ")

推荐答案

string s = arr[i].Replace("\"", "")

Sitecore的解决方案是正确的。看起来你的字符串中有转义字符。如果要排除所有不是字母数字的字符或'：'你可以像这样使用Regex类

Sitecore's solution is correct. It looks like you are getting escape characters in your strings. If you want to exclude all characters that are not alphanumeric or ':' you can use the Regex class like this

string testString = "\"status\":\"ok\"";
var regex = new Regex("[^a-zA-Z0-9 :]");
string cleanedString = regex.Replace(testString, "");
Console.WriteLine(cleanedString);
Console.ReadLine();

它正在做的是匹配所有不是az，AZ，0-9或的字符，并用空字符串替换每个字符。

What it is doing is matching all characters that are not a-z,A-Z,0-9 or : and replacing each with an empty string.

您需要了解C＃中的转义字符和文字。

在C＃中转义：字符，字符串，字符串格式，关键字，标识符 [ ^ ]



取决于字符串的来源，用户输入，外部文件，代码中的文字，可执行文件中的字面值，最终结果不一样。

如果你有\status \：\ok \在源代码中，您将有status：ok在可执行文件中。



解决方案可能是您解决此问题所需要的。

You need to understand escape chars and literals in C#.
Escaping in C#: characters, strings, string formats, keywords, identifiers[^]

Depending on where a string come from, user input, external file, literal in code, literal in executable, the end result is not the same.
if you have "\"status\":\"ok\"" in source code, you will have "status":"ok" in executable.

Solution is probably what you need to solve this problem.
