Replacing text in a string

Question

I need to replace all instances of "" with "null" in my string.

I was going to use

 result.Replace("", "");

but I cant seem to find a way to specify the two ".

As a note that will only be obvious to those that already know it: string.Replace returns a string and does not make the change to result itself (in the example code). — Austin Salonen

Interesting. I headed straight for string.Empty, but that doesn't work. You can't say result.Replace(string.Empty, "null"). — DOK

are you trying to replace the string with null as in the null or are you trying to get "null" as the string? — Eonasdan

Escape quotes:

result.Replace("\"\"", "\"null\""); // will return a new string

[edit] Forgot the quotes in the replacement.

Use the \ escape character:

result.Replace("\"\"", "\"null\"");

I don't imagine they want "null" stored, at least the question doesn't read that way.

Yes I did want null inside the quotes
