サーバーにメッセージを ping して、サーバー上の合計プレーヤーの数値を含むメッセージを取得しようとしています。残念ながら、以下のコードの一部を削除しない限り、以下のコードはフリーズします。
Public Shared Function SocketSendReceive(server As String, port As Integer) As String
'Set up variables and String to write to the server.
Dim ascii As Encoding = Encoding.ASCII
Dim request As String = (DoubleChar(Len(Chr(35))) + Chr(CheckSum(Chr(35)) * 20 Mod 194) + Chr(0) + Chr(35))
Dim bytesSent As [Byte]() = ascii.GetBytes(request)
Dim bytesReceived(255) As [Byte]
' Create a socket connection with the specified server and port.
Dim s As Socket = ConnectSocket(server, port)
If s Is Nothing Then
Return "0"
End If
' Send request to the server.
s.Send(bytesSent, bytesSent.Length, 0)
' Receive the server home page content.
Dim bytes As Int32
' Read the first 256 bytes.
Dim page As [String] = "0"
' The following will block until the page is transmitted.
Do
bytes = s.Receive(bytesReceived, bytesReceived.Length, 0)
page = page + Encoding.ASCII.GetString(bytesReceived, 0, bytes)
Loop While bytes > 0
Return page
End Function
コードのこの部分を削除すると:
Do
bytes = s.Receive(bytesReceived, bytesReceived.Length, 0)
page = page + Encoding.ASCII.GetString(bytesReceived, 0, bytes)
Loop While bytes > 0
ping は通過しますが、値が返されません。誰かが私が間違っていることを指摘できますか?
