【问题讨论】：
【参考方案1】：基本上...
using System;
using System.IO;
using System.Net;
using System.Text;
namespace Examples.System.Net
public class WebRequestPostExample
public static void Main ()
// Create a request using a URL that can receive a post.
WebRequest request = WebRequest.Create ("https://go.urbanairship.com/api/push/");
// Set the Method property of the request to POST.
request.Method = "POST";
// Create POST data and convert it to a byte array.
分成多行，以便您阅读
string postData = "
"device_tokens": [
"some device token",
"another device token"
],
"aliases": [
"user1",
"user2"
],
"tags": [
"tag1",
"tag2"
],
"schedule_for": [
"2010-07-27 22:48:00",
"2010-07-28 22:48:00"
],
"exclude_tokens": [
"device token you want to skip",
"another device token you want to skip"
],
"aps":
"badge": 10,
"alert": "Hello from Urban Airship!",
"sound": "cat.caf"
";
然后
byte[] byteArray = Encoding.UTF8.GetBytes (postData);
// Set the ContentType property of the WebRequest.
request.ContentType = "application/json";
// Set the ContentLength property of the WebRequest.
request.ContentLength = byteArray.Length;
//Do a http basic authentication somehow
string username = "<application key from urban airship>";
string password = "<master secret from urban airship>";
string usernamePassword = username + ":" + password;
CredentialCache mycache = new CredentialCache();
mycache.Add( new Uri( "https://go.urbanairship.com/api/push/" ), "Basic", new NetworkCredential( username, password ) );
request.Credentials = mycache;
request.Headers.Add( "Authorization", "Basic " + Convert.ToBase64String( new ASCIIEncoding().GetBytes( usernamePassword ) ) );
// Get the request stream.
Stream dataStream = request.GetRequestStream ();
// Write the data to the request stream.
dataStream.Write (byteArray, 0, byteArray.Length);
// Close the Stream object.
dataStream.Close ();
// Get the response.
WebResponse response = request.GetResponse ();
// Display the status.
Console.WriteLine (((HttpWebResponse)response).StatusDescription);
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream ();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader (dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd ();
// Display the content.
Console.WriteLine (responseFromServer);
// Clean up the streams.
reader.Close ();
dataStream.Close ();
response.Close ();

【参考方案2】：接受的答案不起作用，您需要更改以下行：
request.ContentType = "application/x-www-form-urlencoded";
到
request.ContentType = "application/json";
完整的工作代码如下所示：
using System;
using System.IO;
using System.Net;
using System.Text;
namespace UrbanAirship_Tes_1
class Program
public static void Main()
// Create a request using a URL that can receive a post.
WebRequest request = WebRequest.Create("https://go.urbanairship.com/api/push/");
request.Credentials = new NetworkCredential("pvYMExk3QIO7p2YUs6BBkg", "rO3DsucETRadbbfxHkd6qw");
// Set the Method property of the request to POST.
request.Method = "POST";
// Create POST data and convert it to a byte array.
//WRITE JSON DATA TO VARIABLE D
string postData = "\"aps\": \"badge\": 1, \"alert\": \"Hello from Urban Airship!\", \"device_tokens\": [\"6334c016fc643baa340eca25bc661d15055a07b475e9a6108f3f644b15dd05ac\"]";
byte[] byteArray = Encoding.UTF8.GetBytes(postData);
// Set the ContentType property of the WebRequest.
request.ContentType = "application/json";
// Set the ContentLength property of the WebRequest.
request.ContentLength = byteArray.Length;
// Get the request stream.
Stream dataStream = request.GetRequestStream();
// Write the data to the request stream.
dataStream.Write(byteArray, 0, byteArray.Length);
// Close the Stream object.
dataStream.Close();
// Get the response.
WebResponse response = request.GetResponse();
// Display the status.
// Console.WriteLine(((HttpWebResponse)response).StatusDescription);
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream();
// Open the stream using a StreamReader for easy access.
StreamReader reader = new StreamReader(dataStream);
// Read the content.
string responseFromServer = reader.ReadToEnd();
// Display the content.
Console.WriteLine(responseFromServer);
// Clean up the streams.
reader.Close();
dataStream.Close();
response.Close();

哇，答案很有效。看起来我是新手，想要同样的，想将数据发送到 iphone、android 和黑莓的应用程序。我是一名从事 sebservice 的网络开发人员，它将向客户端应用程序生成推送消息。 从你的代码我刚刚更改了网络线路的用户名和密码。 System.Net.WebException：远程服务器返回错误：（401）未经授权。在 System.Net.HttpWebRequest.GetResponse() 在 ConsoleApplication1.Program.Main(String[] args) 在 c:\Users\Window8\Downloads\urban-airship-windows-latest\urban-airship-windows-1_0_1_0\ConsoleApplication1\ Program.cs：第 38 行【参考方案3】：public class PushNotificationHelper

【参考方案4】：这是使用 System.Net.Http.HttpClient 异步方法的方法。
var handler = new HttpClientHandler Credentials = new NetworkCredential(urbanairshipapiKey, urbanairshipApiAppMasterSecret) ;
var client = new HttpClient(handler);
var added = client.DefaultRequestHeaders.TryAddWithoutValidation("Accept", "application/vnd.urbanairship+json; version=3;");
var response = await client.PostAsync(apiUrl + "/push/", new StringContent(json, Encoding.UTF8, "application/json"));

【参考方案5】：我编写了一个 c# 库来简化 UrbanAirship API 的使用
