Remove extra space in json string

I am trying to remove all spaces from json formatted string and as a result i need all json in single line string.

Like below

[{"type":"text","label":"FirstName","name":"firstname","subtype":"text","className":"redform-control"},{"type":"select","label":"Profession","className":"form-control","name":"profession","values":[{"label":"StreetSweeper","value":"StreetSweeper"},{"label":"BrainSurgeon","value":"BrainSurgeon"}]},{"type":"textarea","label":"ShortBio:","className":"form-control","name":"short-bio","subtype":"textarea","rows":"4"}]

I have tried but it removes all spaces inside or like

"label":"First Name"

converts into

"label":"FirstName"

I need it in a single line string but inside inverted comma data would not be affected.

What I have tried:

var content = Regex.Replace(jsonContent, @"\s+", string.Empty);

Are you building this JSON serializer? Because if someone else is serializing this, then they should take care of this part.

If you are doing this, then remove any spaces while parsing.

No, I am not building it. I am getting json format and inserting it to database and again trying to use that json and getting exception.

You say you want to remove spaces and also you want it on one line, so are you wanting to remove the spaces or the line breaks?

Regardless this is one of those questions where it looks like you're trying to solve the wrong problem. If you are deserialising your json properly it shouldn't matter that the spaces or line breaks are there.

I want to remove space and line breaks too. As I have mentioned the format above.

use

s = s.Replace("\r\n", "")

to get rid of line breaks, see Solution 1 for the spaces

This thread c# - csharp remove white spaces unless within quotes, ignoring escaped quotes[^] suggests using a JSON parser to do this for you or Wiktor suggests this regex instead

C#

var content = Regex.Replace(jsonContent, @"(""[^""\\]*(?:\\.[^""\\]*)*"")|\s+", "$1");

There is are articles here on CP re parsing JSON that might help
From zero to hero in JSON with C#[^]
Dynamic JSON parser[^]
and possibly Deserialize JSON with C#[^]

Solution 2

Normally, I'd let the JSON serializer do that, but how you tell it to do that will depend on the serializer you use.
But you can minify JSON data with a regex: Minify indented JSON string in .NET - Stack Overflow[^]
