若何在WinForm中要求發送HTTP

手工發送HTTP要求重要是挪用 System.Net的HttpWebResponse辦法

手工發送HTTP的GET要求：

string strURL = "http://localhost/Play/CH1/Service1.asmx/doSearch?keyword=";
strURL +=this.textBox1.Text;
System.Net.HttpWebRequest request;
// 創立一個HTTP要求
request = (System.Net.HttpWebRequest)WebRequest.Create(strURL);
//request.Method="get";
System.Net.HttpWebResponse response;
response = (System.Net.HttpWebResponse)request.GetResponse();
System.IO.Stream s;
s = response.GetResponseStream();
XmlTextReader Reader = new XmlTextReader(s);
Reader.MoveToContent();
string strValue = Reader.ReadInnerXml();
strValue = strValue.WordStr("<","<");
strValue = strValue.WordStr(">",">");
MessageBox.Show(strValue); 
Reader.Close();

手工發送HTTP的POST要求

string strURL = "http://localhost/Play/CH1/Service1.asmx/doSearch";
System.Net.HttpWebRequest request;

request = (System.Net.HttpWebRequest)WebRequest.Create(strURL);
//Post要求方法
request.Method="POST";
// 內容類型
request.ContentType="application/x-www-form-urlencoded";
// 參數經由URL編碼
string paraUrlCoded = System.Web.HttpUtility.UrlEncode("keyword");
paraUrlCoded += "=" + System.Web.HttpUtility.UrlEncode(this.textBox1.Text);
byte[] payload;
//將URL編碼後的字符串轉化為字節
payload = System.Text.Encoding.UTF8.GetBytes(paraUrlCoded);
//設置要求的 ContentLength 
request.ContentLength = payload.Length;
//取得請 求流
Stream writer = request.GetRequestStream();
//將要求參數寫入流
writer.Write(payload,0,payload.Length);
// 封閉要求流
writer.Close();
System.Net.HttpWebResponse response;
// 取得呼應流
response = (System.Net.HttpWebResponse)request.GetResponse();
System.IO.Stream s;
s = response.GetResponseStream();
XmlTextReader Reader = new XmlTextReader(s);
Reader.MoveToContent();
string strValue = Reader.ReadInnerXml();
strValue = strValue.WordStr("<","<");
strValue = strValue.WordStr(">",">");
MessageBox.Show(strValue); 
Reader.Close();
