c# - New Line in Constant error

I am writing a c# code in which i am fetching values from the database and using it. The problem i am facing is as below.

If my fetched value from the database is :

 string cat1 = "sotheby's";

now while using this cat i want to insert an escape character before single quote, to achieve this i have written the below code:

  string cat1 = "sotheby's";
                    if (cat1.Contains("'")) {
                        var indexofquote = cat1.IndexOf("'");
                        cat1.Insert(indexofquote-1,"");
                        var cat2 = cat1;
                    }

The error rises in insert line, the backslash(escape character). The error is New Line in Constant. Please help me how to correct this error.

You can't just write "" in C# code. That will produce the "New Line in Constant" error because it 'escapes' the second quote so that it doesn't count. And the string isn't closed.

Use either "" (escaping the with itself)
or use @"" (a verbatim string).
