RestSharp page creation issue when double quotes in my body.storage.value

[Patch]

I am using RestSharp for creating pages.  Page creation work great when the html body stay simple, without any (") double quotes characters.

This exemple work great for me:

request.AddParameter("application/json", "{\"type\": \"page\",\"title\": \"TEST\",\n " + AncestorString + " \"space\": {\"key\": \"" + ConfluenceSpaceKey + "\" }, \"body\": {\"storage\": {\"value\": \"<h2>Hello World</h2> \", \"representation\": \"storage\" } } }", ParameterType.RequestBody);

As soon I as need to add double quotes characters in the html body:

<h2 style =\"color: Tomato;\"> Hello World </h2>

I get this error:

{"statusCode": 500, "message": "", "reason": "Internal Server Error"}

This exemple don't work for me:

request.AddParameter("application/json", "{\"type\": \"page\",\"title\": \"TEST\",\n " + AncestorString + " \"space\": {\"key\": \"" + ConfluenceSpaceKey + "\" }, \"body\": {\"storage\": {\"value\": \"<h2 style =\"color: Tomato;\"> Hello World </h2> \", \"representation\": \"storage\" } } }", ParameterType.RequestBody);

Any ideas?
Thx!!

Hi @Patch 

so I assume your escaping is wrong: try something like this:

request.AddParameter("application/json", "{\n \"type\": \"page\",\n \"title\": \"new page22\",\n \"space\": {\n \"key\": \"TS\"\n },\n \"body\": {\n \"storage\": {\n \"value\": \"<p style=\\\"color:red\\\">This is a new page</p>\",\n \"representation\": \"storage\"\n }\n }\n}", ParameterType.RequestBody);
