这不是工作>

String ali = "<CC5Request><Name>Mert</Name><Password>123</Password><ClientId>xxxx</ClientId><IPAddress>213</IPAddress><Adress>asdsa</Adress>" + 
         "<OrderId>123</OrderId><Type>Auth</Type><Number>1234567891234567</Number><ExpiresAy>01</ExpiresAy><ExpiresYil>13</ExpiresYil><Cvv2Val>123</Cvv2Val>" +

        StreamReader loResponseStream = 

         new StreamReader(loWebResponse.GetResponseStream(), enc); 

        string lcHtml = loResponseStream.ReadToEnd(); 
        loWebResponse.Close(); 
        loResponseStream.Close();

编辑：实验1

String postData = "Name=Mert" + 
       "&Password=123" + 
       "&ClientId=1058" + 
       "&IPAddress=213.456.654.456" + 
       "&Adress=asdsa" + 
       "&OrderId=123" + 
       "&Type=Auth" + 
       "&Number=4522115422659661" + 
       "&ExpiresAy=01" + 
       "&ExpiresYil=13" + 
       "&Cvv2Val=123" + 
       "&Total=10" + 
       "&Taksit=1" + 
       "&Kdv=18" + 
       "&BankaID=1" + 
       "&TcKimlik=12345678912"; 

      string URI = "http://www.pay-pos.com/test.php"; 

      WebClient wc = new WebClient(); 
      wc.Headers["Content-type"] = "application/x-www-form-urlencoded"; 
      string HtmlResult = wc.UploadString(URI, postData);

实验2

HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://www.pay-pos.com/test.php"); 
     request.Method = WebRequestMethods.Http.Post; 
     request.ContentLength = postData.Length; 
     request.ContentType = "application/x-www-form-urlencoded"; 
     request.KeepAlive = false; //also tried true as well 

     StreamWriter writer = new StreamWriter(request.GetRequestStream()); 
     writer.Write(postData); 
     writer.Close(); 
     HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 
     StreamReader reader = new StreamReader(response.GetResponseStream()); 
     String responseString = reader.ReadToEnd(); 

     response.Close();

实验3 !!!工作！

String ali = "datafromuser=<CC5Request><Name>Mert</Name><Password>123</Password><ClientId>1058</ClientId><IPAddress>213.456.654.456</IPAddress><Adress>asdsa</Adress><OrderId>123</OrderId><Type>Auth</Type>" + 
"<Number>4522115422659661</Number><ExpiresAy>01</ExpiresAy><ExpiresYil>13</ExpiresYil><Cvv2Val>123</Cvv2Val><Total>10</Total><Taksit></Taksit><Kdv>18</Kdv><BankaID>1</BankaID>"+ 
"<TcKimlik>12345678912</TcKimlik></CC5Request>"; 

      byte[] byteArray = System.Text.Encoding.UTF8.GetBytes(ali); 

      WebRequest req = WebRequest.Create("http://www.pay-pos.com/test.php"); 

      req.ContentType = "application/x-www-form-urlencoded"; 
      req.ContentLength = byteArray.Length; 
      req.Method = "POST"; 

      Stream dataStream = req.GetRequestStream(); 
      dataStream.Write(byteArray, 0, byteArray.Length); 
      dataStream.Close(); 

      HttpWebResponse response = (HttpWebResponse)req.GetResponse(); 
      StreamReader reader = new StreamReader(response.GetResponseStream()); 
      String responseString = reader.ReadToEnd(); 

      response.Close();

＃ 3看起来接近完成... add req.Method =“POST”; – 2012-07-09 12:28:58

＃1和＃2没有发布正确的表单，因为服务器期望。 – 2012-07-09 12:31:13

我看到错误的第一件事就是您尝试使用查询字符串发布表单数据。你的“表单数据”应该是这样的：

String ali = "datafromuser=<CC5Request><Name>Mert</Name><Password>123</Password><ClientId>xxxx</ClientId><IPAddress>213</IPAddress><Adress>asdsa</Adress>" + 
          "<OrderId>123</OrderId><Type>Auth</Type><Number>1234567891234567</Number><ExpiresAy>01</ExpiresAy><ExpiresYil>13</ExpiresYil><Cvv2Val>123</Cvv2Val>" + 
          "<Total>10</Total><Taksit></Taksit><Kdv>xx</Kdv><BankaID>1</BankaID><TcKimlik>12345678912</TcKimlik></CC5Request>";

接下来，你需要从表单数据中获取字节[]。

byte[] byteArray = Encoding.UTF8.GetBytes(ali);

设置一些标题：

req.ContentType = "application/x-www-form-urlencoded"; 
req.ContentLength = byteArray.Length; 
req.Method = "POST";

现在你的数据写入请求流。

Stream dataStream = req.GetRequestStream(); 
dataStream.Write(byteArray, 0, byteArray.Length); 
dataStream.Close();

终于...得到您的回应。还要注意，任何实现IDisposable的应该包含在using声明中，即Stream和WebResponse。

另请注意，提交按钮不是您的表单发布数据的一部分。服务器可能期待它。

@Mert - 请用你的新代码更新你的答案，而不是覆盖旧的东西......只是将它附加到底部，就像“编辑 - 尝试以下并得到错误<你的错误在这里> – 2012-07-09 12:18:36

好的，我会感谢 – Mert 2012-07-09 12:20:23

这可能对你有帮助。

string URI = "http://www.myurl.com/post.php"; 
string myParamters = "param1=value1&param2=value2"; 

WebClient wc = new WebClient(); 
wc.Headers["Content-type"] = "application/x-www-form-urlencoded"; 
string HtmlResult = wc.UploadString(URI, myParameters);

我同意，WebClient对初学者来说可能会容易得多。 – 2012-07-09 11:58:57

默特尔，请让我知道它是否对你有帮助。 – 2012-07-09 12:02:13

刚刚尝试抱歉，迟到的答案，答案是“\ n”这意味着我们不能使它的工作:(也不应该我指定“datafromuser”在某些？ – Mert 2012-07-09 12:19:01

这是simples例子。 POSTDATA取决于形式

String postData = "Name=" + Username + 
       "&Password=" + Password + 
       "&Retype=" + Password + 
       "&Email=" + HttpUtility.UrlEncode(EmailAddress) + 
       "&RealName=" + String.Format("{0}+{1}", FirstName.Replace(" ", "+"), LastName.Replace(" ", "+"));

现在创建请求后的数据：

HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url); 
request.Method = WebRequestMethods.Http.Post; 
request.ContentLength = postData.Length; 
request.ContentType = "application/x-www-form-urlencoded"; 
request.KeepAlive = false; 

StreamWriter writer = new StreamWriter(request.GetRequestStream()); 
writer.Write(postData); 
writer.Close(); 
HttpWebResponse response = (HttpWebResponse)request.GetResponse(); 
StreamReader reader = new StreamReader(response.GetResponseStream()); 
String responseString = reader.ReadToEnd(); 

response.Close();

可以为了赶POSTDATA看起来如何使用Fiddler。

你可以给我的URL你想通过代码做http发布吗？ – 2012-07-09 12:12:18

这是问题发布别人的例子。 @Mert，你需要使用你的元素名称，即“datafromuser = {文本区域中的所有内容}” – 2012-07-09 12:15:17

试试这个。

using (WebClient client = new WebClient()) 
    { 

     byte[] response = client.UploadValues("http://dork.com/service", new NameValueCollection() 
     { 
      { "home", "Cosby" }, 
      { "favorite+flavor", "flies" } 
     }); 
    }

，将需要这些包括：

using System; 
using System.Collections.Specialized; 
using System.Net;

如果你在使用一个静态方法/班坚持：

public static class Http 
{ 
    public static byte[] Post(string uri, NameValueCollection pairs) 
    { 
     byte[] response = null; 
     using (WebClient client = new WebClient()) 
     { 
      response = client.UploadValues(uri, pairs); 
     } 
     return response; 
    } 
}

然后简单：

Http.Post("http://dork.com/service", new NameValueCollection() { 
    { "home", "Cosby" }, 
    { "favorite+flavor", "flies" } 
});
