Describe the Issue

When using "Code snippet" > "C# - HttpClient", the code generated is invalid and will not run.

Steps To Reproduce

Import the following curl request (I used a real request, but changed some values for the sake of privacy):

curl "https://myurl.com/endpoint" ^
  -H "accept: application/json, text/plain, */*" ^
  -H "accept-language: en-US,en;q=0.8" ^
  -H "authorization: Bearer MYTOKEN" ^
  -H "content-type: application/json;charset=UTF-8" ^
  -H "origin: https://origin.myurl.com" ^
  -H "referer: https://referer.myurl.com/" ^
  -H ^"sec-ch-ua: ^\^"Brave^\^";v=^\^"123^\^", ^\^"Not:A-Brand^\^";v=^\^"8^\^", ^\^"Chromium^\^";v=^\^"123^\^"^" ^
  -H "sec-ch-ua-mobile: ?0" ^
  -H ^"sec-ch-ua-platform: ^\^"Windows^\^"^" ^
  -H "sec-fetch-dest: empty" ^
  -H "sec-fetch-mode: cors" ^
  -H "sec-fetch-site: same-site" ^
  -H "sec-gpc: 1" ^
  -H "user-agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/123.0.0.0 Safari/537.36" ^
  --data-raw ^"^{^\^"TeamIds^\^":^[57566^],^\^"StartTime^\^":^\^"2024-03-01T00:00:00.000Z^\^",^\^"EndTime^\^":^\^"2024-05-31T23:59:59.999Z^\^"^}^"

After importing the above request, generate a code snippet using "Code snippet" > "C# - HttpClient". The following snippet is generated:

var client = new HttpClient();
var request = new HttpRequestMessage(HttpMethod.Post, "https://myurl.com/endpoint");
request.Headers.Add("accept", "application/json, text/plain, */*");
request.Headers.Add("accept-language", "en-US,en;q=0.8");
request.Headers.Add("authorization", "Bearer MYTOKEN");
request.Headers.Add("content-type", "application/json;charset=UTF-8");
request.Headers.Add("origin", "https://origin.myurl.com");
request.Headers.Add("referer", "https://referer.myurl.com/");
request.Headers.Add("sec-ch-ua", "\"Brave\";v=\"123\", \"Not:A-Brand\";v=\"8\", \"Chromium\";v=\"123\"");
request.Headers.Add("sec-ch-ua-mobile", "?0");
request.Headers.Add("sec-ch-ua-platform", "\"Windows\"");
request.Headers.Add("sec-fetch-dest", "empty");
request.Headers.Add("sec-fetch-mode", "cors");
request.Headers.Add("sec-fetch-site", "same-site");
request.Headers.Add("sec-gpc", "1");
request.Headers.Add("user-agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/123.0.0.0 Safari/537.36");
var content = new StringContent("{\"TeamIds\":[57566],\"StartTime\":\"2024-03-01T00:00:00.000Z\",\"EndTime\":\"2024-05-31T23:59:59.999Z\"}", null, "application/json;charset=UTF-8");
request.Content = content;
var response = await client.SendAsync(request);
response.EnsureSuccessStatusCode();
Console.WriteLine(await response.Content.ReadAsStringAsync());

However, the above code is invalid in multiple ways and will not run.

Here is the correct equivalent code:

var client = new HttpClient();
client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json")); //Content-Type header must be specified in this way
var request = new HttpRequestMessage(HttpMethod.Post, "https://myurl.com/endpoint");
request.Headers.Add("accept", "application/json, text/plain, */*");
request.Headers.Add("accept-language", "en-US,en;q=0.8");
request.Headers.Add("authorization", "Bearer MYTOKEN");
request.Headers.Add("origin", "https://origin.myurl.com");
request.Headers.Add("referer", "https://referer.myurl.com/");
request.Headers.Add("sec-ch-ua", "\"Brave\";v=\"123\", \"Not:A-Brand\";v=\"8\", \"Chromium\";v=\"123\"");
request.Headers.Add("sec-ch-ua-mobile", "?0");
request.Headers.Add("sec-ch-ua-platform", "\"Windows\"");
request.Headers.Add("sec-fetch-dest", "empty");
request.Headers.Add("sec-fetch-mode", "cors");
request.Headers.Add("sec-fetch-site", "same-site");
request.Headers.Add("sec-gpc", "1");
request.Headers.Add("user-agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/123.0.0.0 Safari/537.36");
var content = new StringContent("{\"TeamIds\":[57566],\"StartTime\":\"2024-03-01T00:00:00.000Z\",\"EndTime\":\"2024-05-31T23:59:59.999Z\"}", System.Text.Encoding.UTF8, "application/json"); //This is the proper way to specify encoding
request.Content = content;
var response = await client.SendAsync(request);
response.EnsureSuccessStatusCode();
Console.WriteLine(await response.Content.ReadAsStringAsync());

Additional Context?

There are other ways to improve the C# code above (for instance, JsonContent instead of StringContent) but this is the minimal amount of changes to make the code useable
