如何在字符串或字符中声明 ^\

Question

I would like to declare ^\ this as a string or character. I used the below but i am getting an error

 string str="^\";

So can any one help me

Answer 1

You have to escape the backslash.

string str = "^\\";

Or, you can use the verbatim syntax.

string str = @"^\";

Answer 2

\ is the escape token, you have to double it to use it as a literal in a string:

string str = "^\\";

Alternatively, you can use literal string syntax:

string str = @"^\";

Answer 3

You need to escape backslash characters, so instead of:

string str = "^\";

use:

string str = "^\\";

Answer 4

I have no idea about C#, but can you try:

string str="^\\";
