关于TCP客户端接收数据格式乱码

Question

关于TCP客户端接收数据格式乱码，是一个485串口服务器网关连接电脑，485接线到电表读取用电量

发送 01 04 00 00 00 02 71 CB 接收到的是乱码

这是处理发送的代码
 Sub SendMsg(ByVal Msg As String) '发送数据
        Dim sendData As String = TxtSendMsg.Text
        Try '捕获异常
            sendData.Replace("0x", "")
            sendData.Replace("0x", "")
            Dim strArray() As String = sendData.Split(New Char() {",", "，", "\r", "\n", " ", "\t"})
            Dim decnum As Integer = 0
            Dim i As Integer = 0
            Dim sendBuffer() As Byte = New Byte(strArray.Length) {}
            Dim str As String
            For Each str In strArray
                Try
                    decnum = Convert.ToInt16(str, 16)
                    sendBuffer(i) = Convert.ToByte(decnum)
                    i = i + 1
                Catch

                End Try
            Next
            SockClient.Send(sendBuffer)
        Catch ss As SocketException
            ShowMsg(ss.Message)
            Return
        Catch s As Exception
            ShowMsg(s.Message)
            Return
        End Try

        ShowMsg("发送：" & Msg)
    End Sub

这是接收的代码

Sub RecMsg() '接受数据处理
        Dim buffMsgRec() As Byte = New Byte(1024 * 1024 * 10) {}
        Dim length As Integer = -1
        While True
            Try '捕获异常

                length = SockClient.Receive(buffMsgRec)

            Catch ss As SocketException
                ShowMsg(ss.Message)
                Return
            Catch s As Exception
                ShowMsg(s.Message)
                Return
            End Try

            Dim StrMsg As String
            StrMsg = System.Text.Encoding.UTF8.GetChars(buffMsgRec, 0, length)

            ShowMsg("接收：" & StrMsg)
        End While
    End Sub

Answer 1

把接收的十六进制数据转成字符串形式显示
