JSON Question

Newtonsoft.Json SerializeObject without escape backslashes

Given the code:

dynamic foo = new ExpandoObject();
foo.Bar = "something";
string json = Newtonsoft.Json.JsonConvert.SerializeObject(foo);


The output is below:

"{\"Bar\":\"something\"}"


When debugging a large json document it is hard to read - using the built in features of Newtonsoft.Json (not regex or hacks that could break things) is there any way to make the output a string with the valie:

{Bar: "something"}

Answer

What you see in debugger when looking at the json value is the string value that you should use in a C# file to obtain the same value.

Indeed you could replace

dynamic foo = new ExpandoObject();
foo.Bar = "something";
string json = Newtonsoft.Json.JsonConvert.SerializeObject(foo);

with

string json = "{\"Bar\":\"something\"}";

without changing the program's behaviour.

Thus, to obtain a different value, you should change how JsonConvert works, but JsonConvert conforms to the JSON standard, thus forget it!

If you are not actually serializing ExpandoObject (nor any other sealed class out of your control), you can use the DebuggerDisplayAttribute on the types that you are serializing in json, to define how the object will be shown during debug (in your code, the foo instance).

But a string is a string and VisualStudio is right: double-quotes must be escaped.
