Passing variables into verbatim string literal for JSON request body

Question

Fairly new to C# and I'm trying to build a clean-ish multi line string using a verbatim string literal, but also trying to pass in variables to it.

Says it is not formatted correctly, so seeing what I am doing wrong here, as this format is close to what I've seen in other SO questions.

  var bodyJson =string.Format(@"{
                                  ""[email protected]"": ""/consultingprojectses({0})"",
                                  ""[email protected]"": ""products(f4b6b505-99df-e711-8108-c4346bdc3201)"",
                                  ""[email protected]"": ""/contacts({1})"",
                                  ""[email protected]"": ""/accounts({2})""
                                }", projectRecord.consultingprojectsid, contact, projectRecord.account_value);

Or preferably this:

  var bodyJson =string.Format(@"{
                                  '[email protected]': '/consultingprojectses({0})',
                                  '[email protected]': 'products(f4b6b505-99df-e711-8108-c4346bdc3201)',
                                  '[email protected]': '/contacts({1})',
                                  '[email protected]': '/accounts({2})'
                                }", projectRecord.consultingprojectsid, contact, projectRecord.account_value);

JSON is serialized data from a model or object; rather than concocting a fancy string use a serializer — Ňɏssa Pøngjǣrdenlarp

Please don't do this. Create an object and use a serializer! — user47589

You may want to consider using JObject to create the necessary structure and values rather than trying to escape and all that; for instance, technically you have invalid JSON because strings must use double quotes, not single quotes. — Heretic Monkey

Why not try replace by placing some place holder like bodyJson.Replace("{0}","myvalue") — Jaydip Jadhav

Create an object and use a serializer to construct your Json:

var obj = new
            {
                Key1 = "value1",
                Key2 = "value2"
            };

var json = JsonConvert.SerializeObject(obj);
