查找数据包丢失和.NET中跟踪路由

Question

我想代码捕获计算机上的数据包丢失，但我已经能够做到这一点的唯一方法是运行NETSTAT.EXE和TraceRt.exe流程并将捕捉到一个列表框（使用下面的代码）：

Private Sub myProcess()
    Dim p As System.Diagnostics.Process
    Dim theFile, sTemp, sLineOut, mySent, myRetrans As String
    Dim intSentStart As Double
    Dim isEnabled As Boolean

    p = New System.Diagnostics.Process
    theFile = t.Name

    If File.Exists("c:\windows\system32\" & theFile) Then
        theFile = "c:\windows\system32\" & theFile
    Else
        MessageBox.Show("Unable to find the " & theFile & " file on your computer.", "File Find Error!", MessageBoxButtons.OK, MessageBoxIcon.Error)
    End If

    Select Case t.Name
        Case "TraceRt.exe"
            p.StartInfo.Arguments = "-h 30 www.stackoverflow.com"

        Case "NetStat.exe"
            p.StartInfo.Arguments = "-s -p tcp"
    End Select

    Try
        p.StartInfo.FileName = theFile
        p.StartInfo.CreateNoWindow = True
        p.StartInfo.UseShellExecute = False
        p.StartInfo.RedirectStandardOutput = True
        p.Start()
        p.PriorityClass = System.Diagnostics.ProcessPriorityClass.Normal

        sLineOut = ""

        Do While Not p.HasExited
            sTemp = p.StandardOutput.ReadLine()
            If sTemp <> "" Then
                sLineOut = sLineOut & sTemp & vbNewLine
                'Send to listbox
                setTrace(sTemp)
            End If
        Loop
        If sLineOut = "" Then
            'Clear Listbox
            clearTrace()
            myProcess()
            Exit Sub
        End If
        If t.Name = "NetStat.exe" Then
            Try
                If lboxTrace.Items.Count < 9 Then
                    'Clear Listbox
                    clearTrace()
                    myProcess()
                    Exit Sub
                End If
                mySent = ""
                mySent = lboxTrace.Items.Item(8) '("Segments Sent")
                mySent = Trim(mySent.Replace("Segments Sent", ""))
                mySent = Trim(mySent.Replace("=", ""))

                myRetrans = ""
                myRetrans = lboxTrace.Items.Item(9)
                myRetrans = Trim(myRetrans.Replace("Segments Retransmitted", ""))
                myRetrans = Trim(myRetrans.Replace("=", ""))

                intSentStart = Math.Round((myRetrans / mySent) * 100, 2)

                'setTrace sends data to the listbox
                If intSentStart < 2 Then
                    setTrace("Your Current Packet Loss is: " & intSentStart & "%.")
                    setTrace("Your packet loss is within acceptable ranges.")
                Else
                    setTrace("Your Current Packet Loss is: " & intSentStart & "%.")
                    setTrace("Your packet loss is below acceptable ranges!")
                    setTrace("Please contact your Internet Provider about your Internet Connection.")
                End If

            Catch ex As Exception
                'Clear Listbox
                clearTrace()
                myProcess()
                Exit Sub
            End Try
        End If
    Catch ex As Exception
        MessageBox.Show(ex.Message)
    End Try

End Sub

有没有人有更好的主意来获取这些信息？我宁愿使用，而不是通过这种方式黑客托管代码。

先谢谢了！ -JFV

不知道这是你在寻找什么，但你采取了看的 Ping类？

编辑：其实对于路由跟踪，看看这里的答案：路由跟踪和Ping在C＃ 。

有关的Netstat，看一看 HTTP：// towardsnext .wordpress.com / 2009/02/09 / netstat的功能于C / 。
