试试这个

var c = new HttpClient
{
    BaseAddress = new Uri("Your URL")
};

c.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));

var json = "Your json string"

var req = new HttpRequestMessage(HttpMethod.Post, "Your Method name in URI Template")
{
    Content = new StringContent(json, Encoding.UTF8, "application/json")
};
c.SendAsync(req).ContinueWith(respTask =>
{
    var response = respTask.Result.Content.ReadAsStringAsync();
    Console.WriteLine("Response: {0}", respTask.Result);
});
}
