如何从C#向ASP.Net web api发出POST请求.我使用了Newtonsoft DLL文件来创建json,但是,我无法将其发送到api.

我的代码是:

        Login login = new Login
        {
            userid = username.Text,
            pass = pass.Text
        };
        string json = JsonConvert.SerializeObject(login, Formatting.Indented);

如何将此json发送到web api,并获得响应？

        httpWebRequest.Accept = "application/json; charset=utf-8";

        using (var streamWriter = new StreamWriter(httpWebRequest.GetRequestStream()))
        {

            json = json.Replace("\r\n","");
            //json = json.Replace("\",", "\","   + "\"" +"\u002B");
            streamWriter.Write(json);
            streamWriter.Flush();
            streamWriter.Close();
        }

        var httpResponse = (HttpWebResponse)httpWebRequest.GetResponse();
        using (var streamReader = new StreamReader(httpResponse.GetResponseStream()))
        {
            var result = …
