用vb.net如何向服务器发送request请求并获取结果？

最好有源代码！

用System.Net空间里的WebClient或HttpWebRequest/HttpWebResponse类, 参考下面这个例子

http://dev.kanngard.net/Permalinks/ID_20040422161020.html

Dim postData As String
postData = "username=MyUserName&password=mysecretpassword1234"
Dim request As HttpWebRequest
Dim response As HttpWebResponse
request = CType(WebRequest.Create("http://server.com/?Login"), HttpWebRequest)
request.ContentType = "application/x-www-form-urlencoded"
request.ContentLength = postData.Length
request.Method = "POST"
request.AllowAutoRedirect = False

Dim requestStream As Stream = request.GetRequestStream()
Dim postBytes As Byte() = Encoding.ASCII.GetBytes(postData)
requestStream.Write(postBytes, 0, postBytes.Length)
requestStream.Close()
response = CType(request.GetResponse(), HttpWebResponse)

Console.WriteLine(New StreamReader(response.GetResponseStream()).ReadToEnd())
Console.WriteLine("Headers:")
Console.WriteLine(response.Headers.ToString())
