How to write all keys and values within Dictionary<string, object> to a text file?

Question

I have a Dictionary<string, object> advertiserResponse that looks like this...

"AdvertiserLookup": {
          "Agency": {
            "AgencyAlpha": "ABC",
            "Media": [
              {
                "Code": "123",
                "Name": "XYZ",
                "Advertisers": {
                  "Advertiser": [
                    {
                      "Code": "JKL",
                      "Name": "EFG",
                      "BusinessKey": "HIJ"
                    },
                    {
                      "Code": "KLM",
                      "Name": "NOP",
                      "BusinessKey": "QRS"
                    },
                    {

This is the line I'm using to try to write to a text file:

File.WriteAllLines("test.txt", advertiserResponse.Select(x => "[" + x.Key + " " + x.Value + "]").ToArray());

I'm expecting the Json (not necessary in pretty print) with all keys and text below AdvertiserLookup. What I get in test.txt:

[AdvertiserLookup System.Collections.Generic.Dictionary``2[System.String,System.Object]]

How do I write the entire thing to text?

Give Json.NET a try. You should be able to serialize your dictionary.

var jsonString = JsonConvert.SerializeObject(advertiserResponse, Formatting.Indented)
