WinForm passing parameters to URLs and getting return values

In the WinForm call URL and pass parameters mainly use HttpWebRequest object, divided into two forms of post and get, personal feeling is to simulate the browser,

1.post Method:

<summary>
Using the Post method, call the SMS interface
</summary>
<param name= "PhoneNumber" ></param>
<param name= "Smscontent" ></param>
<param name= "Phonenumbertype" ></param>
<param name= "Smsuser" ></param>
private void Callmsgcentertosendmsgpost (String phonenumber, String smscontent, String Phonenumbertype, String smsuser)
{
String formurl = configurationsettings.appsettings["Formurl"]. ToString (). Trim ();//url address
String formData = "phonenumber=" + PhoneNumber + "&smscontent=" +smscontent + "&phonenumbertype=" + Phonenumbertyp E + "&smsuser=" + Smsuser + "";
Cookiecontainer Cookiecontainer = new Cookiecontainer ();
Converts a committed string data into a byte array
byte[] PostData = Encoding.UTF8.GetBytes (FormData);

Set the relevant parameters for the submission
HttpWebRequest request = WebRequest.Create (Formurl) as HttpWebRequest;
Encoding myencoding = encoding.getencoding ("gb2312");
Request. Method = "POST";
Request. KeepAlive = false;
Request. AllowAutoRedirect = true;
Request. ContentType = "application/x-www-form-urlencoded";
Request. useragent = "mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1;. NET CLR 2.0.50727;. NET CLR 3.0.04506.648;. NET CLR 3.5.21022;. NET CLR 3.0.4506.2152;. NET CLR 3.5.30729) ";
Request. Cookiecontainer = Cookiecontainer;
Request. ContentLength = Postdata.length;

Submit Request Data
System.IO.Stream outputstream = Request. GetRequestStream ();
Outputstream.write (postdata, 0, postdata.length);
Outputstream.close ();

HttpWebResponse response;
Stream Responsestream;
StreamReader reader;
String srcstring;
Response = Request. GetResponse () as HttpWebResponse;
Responsestream = Response. GetResponseStream ();
reader = new System.IO.StreamReader (Responsestream, Encoding.UTF8);
srcstring = reader. ReadToEnd ();
Reader. Close ();
}

2,get method

//<summary>
//Use the Get method
//</summary>
//<param name= "PhoneNumber" ></param>
//<param name= "Smscontent" ></PARAM>
//<param name= "Phonenumbertype" ></param>
//<param name= "Smsuser" ></PARAM>
private void Callmsgcentertosendmsgget (String phonenumber, String smscontent, String Phonenumbertype, String smsuser)
{
String formurl = configurationsettings.appsettings[ "Formurl"]. ToString (). Trim ();
String formData = "phonenumber=" + httputility.urlencode (phonenumber) + "&smscontent=" + httputility.urlencode ( smscontent) + "&phonenumbertype=" + httputility.urlencode (phonenumbertype) + "&smsuser=" + Httputility.urlencode (Smsuser) + "";
Cookiecontainer Cookiecontainer = new Cookiecontainer ();

Formurl = Formurl + "?" + FormData;
Set the relevant parameters for the submission
HttpWebRequest request = WebRequest.Create (Formurl) as HttpWebRequest;

Request. Method = "GET";
Request. KeepAlive = false;
Request. AllowAutoRedirect = true;
Request. ContentType = "application/x-www-form-urlencoded";
Request. useragent = "mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1;. NET CLR 2.0.50727;. NET CLR 3.0.04506.648;. NET CLR 3.5.21022;. NET CLR 3.0.4506.2152;. NET CLR 3.5.30729) ";
Request. Cookiecontainer = Cookiecontainer;

HttpWebResponse sendsmsresponse = (httpwebresponse) request. GetResponse ();

StreamReader Sendsmsresponsestream = new StreamReader (Sendsmsresponse.getresponsestream ());

String strrespone = Sendsmsresponsestream.readtoend ();

Sendsmsresponse.close ();
Sendsmsresponsestream.close ();
}

3, the call is relatively simple, mainly in the process of passing parameters to pay attention to the processing of Chinese, otherwise it will become garbled, get the return value of course, using the HttpWebResponse object
