C# JsonElement to string without formatting

February 15, 2022

I need to convert a JsonElement to string but without any carriage return, tabs or spaces. A simple ToString() works but leaves those in:

data.ToString()

Results:

"{\r\n "Field1": "Value1",\r\n "Field2": "Value2"\r\n }"

Looking for:

"{"Field1": "Value1","Field2":"Value2"}"

Sure I could do a simple find and replace string command. However, there will be some fields that will contain carriage return, or tabs or spaces and I don’t want to change those.

>Solution :

In .NET 6 you can use JsonNode.ToJsonString() (using the System.Text.Json.Nodes namespace), but you’d need to convert from the JsonElement to a JsonObject first:

var jsonObject = JsonObject.Create(data);
Console.WriteLine(jsonObject.ToJsonString());

ToJsonString() takes JsonSerializerOptions as parameter so you could specify WriteIndented if you wanted different behaviour, but by default it will output with WriteIndented = false (which is your desired format).
