How to change the a Header of HttpContent

I have this code to change the Header of my content from {text/plain; charset=utf-8} to "{application/json}"

using (System.Net.Http.HttpClient client = new System.Net.Http.HttpClient())
{
    string content = "some json data";
    System.Net.Http.StringContent sc = new System.Net.Http.StringContent(content);
    sc.Headers.Remove("Content-Type"); // "{text/plain; charset=utf-8}"
    sc.Headers.Add("Content-Type", "application/json");
    System.Net.Http.HttpResponseMessage response = client.PostAsync("http://foo.bar", sc).Result;
}

Is there a way to modify it directly instead of removin and adding it?

If you are building json string manuallly by serializing some data, then there is much better way. You can use PostAsJsonAsync extension method:

using (System.Net.Http.HttpClient client = new System.Net.Http.HttpClient())
{
    var response = await client.PostAsJsonAsync("http://foo.bar", data);
}

It will automatically do following things

  • Serialize data to JSON
  • Create StringContent
  • Provide correct application/json media type

Use this overload of StringContent for setting content-type

sc = new StringContent(content, Encoding.UTF8, "application/json");

After this, you don't need to add/remove header values.
