How To Escape Quotation Marks in Multiple Line Of String? C#

Question

I have a string with multiple lines, each line contains number of Quotation mark ("),these Quotations are too much in my string and some of them even I cant skip with back slash() also. I tried to use 31d party website ( click here ) which will do Escapeing but its reforming the lines which I need my string in its line format so I can regex them line by line. Question is there any way to skip all these quotations in easy way?

bellow is mock of my string

var stringHolder = @" book book "book"
ten ten "book" book pen
pen "hook book" dook
beer poor "111" cat map"

Tnx alot in advance

English is not my first language, but when you say "skip" you mean "escape" ? — cantSleepNow, Dec 12 '18 at 21:17

What are you trying to accomplish? In C# if you use a [verbatim string literal](https://learn.microsoft.com/en-us/dotnet/csharp/language-reference/tokens/verbatim) then you must double up `"` marks inside it. — NetMage, Dec 12 '18 at 21:20
how can I see the other question ? so I can compare it with mine @NetMage — , Dec 13 '18 at 22:14

To escape double quotes in a verbatim string (ie, a string declared with the @ prefix), simply double the quotes up (""). This is in contrast to how you would normally escape a double quote in a string, \".

var stringHolder = @" book book ""book""
ten ten ""book"" book pen
pen ""hook book"" dook
beer poor ""111"" cat map";
Console.WriteLine(stringHolder);
/*Output:
 book book "book"
ten ten "book" book pen
pen "hook book" dook
beer poor "111" cat map
*/

When the indentation matters, you may have to fight the normal tabbing in your editor a bit, which can lead to some odd looking declarations.

namespace MyNamespace {
    public class Foo {
        public string GetString() => @"Hello
World"; // Returns a string that looks like
        // Hello
        // World

        public string GetString2() => @"Hello
            World"; // Returns a string that looks like
                    // Hello
                    //             World
    }
}

While this feature is currently in preview for C# 11, the following way of declaring multi-line strings that contain quotes is likely to be available in the coming future.

var stringHolder = """
     book book "book"
    ten ten "book" book pen
    pen "hook book" dook
    beer poor "111" cat map
    """;
    
    Console.WriteLine(stringHolder);
/*Output:
 book book "book"
ten ten "book" book pen
pen "hook book" dook
beer poor "111" cat map
*/

At the moment, the rules for how many quotes (in this example, 3) that are required is that the header and footer quotes be at least 3, or N+1 the amount of consecutive quotes expected in the string.
