GetResponse不是System.Net.WebRequest的成员 [英] GetResponse is not a member of System.Net.WebRequest

问题描述

你好，
我正在使用VB创建win 8应用，由于GetResponse不是System.Net.WebRequest的成员，因此在代码段之后出现错误

Hello,
I am creating win 8 app using VB, I am getting error following snippet as GetResponse is not a member of System.Net.WebRequest

Dim msg As String
Function sendSMS(ByVal numbers As String, ByVal msg As String, ByVal provider As String, ByVal username As String, ByVal password As String)
 Try
 Dim myReq As HttpWebRequest = DirectCast(WebRequest.Create("http://ultimatesmsapi.tk/sms.php?username=" + username + "&password=" + password + "&msg=" + msg + "&numbers=" + numbers + "&provider=" + provider), HttpWebRequest)
 Dim myResp As HttpWebResponse = DirectCast(myReq.GetResponse(), HttpWebResponse)
 Dim respStreamReader As New System.IO.StreamReader(myResp.GetResponseStream())
 Dim responseString As String = respStreamReader.ReadToEnd()
 If responseString = 1 Then
 msg = "SMS sent successfully.."
 ElseIf responseString = -1 Then
 msg = "Username and password is incorrect"
 ElseIf responseString = -2 Then
 msg = "Some fields are missing!"
 ElseIf responseString = -3 Then
 msg = "Error while sending sms!"
 ElseIf responseString = -4 Then
 msg = "Invalid Provider!"
 ElseIf responseString = -5 Then
 msg = "Number is DND activated!"
 End If
 respStreamReader.Close()
 myResp.Close()
 Catch ex As Exception
 msg = "Problem in connection to server.."
 End Try
 Return msg
 End Function

推荐答案

您是否在项目属性中添加了对System.Net.dll的引用?

Did you add a reference to System.Net.dll in your Project Properties??
