c# - 蓝牙文件发送

Question

我是蓝牙开发新手，我发现了 32netfeet 。现在我可以搜索附近的蓝牙设备并连接到它们，但如何发送文件，例如 SendTest.txt？我尝试使用 OBEX 的 ButtonClick 事件，但我不明白这是我的示例代码:

using InTheHand.Net;
using InTheHand.Net.Sockets;
using InTheHand.Net.Bluetooth;

namespace BluetoothIntheHand
{
    public partial class Form2 : Form
    {
        private Guid service = BluetoothService.DialupNetworking;
        private BluetoothClient bluetoothClient;

        public Form2()
        {
            InitializeComponent();
        }

        private void btnSearch_Click(object sender, EventArgs e)
        {

                BluetoothRadio.PrimaryRadio.Mode = RadioMode.Discoverable;
                BluetoothRadio myRadio = BluetoothRadio.PrimaryRadio;
                lblSearch.Text = "" + myRadio.LocalAddress.ToString();

                bluetoothClient = new BluetoothClient();
                Cursor.Current = Cursors.WaitCursor;
                BluetoothDeviceInfo[] bluetoothDeviceInfo = { };
                bluetoothDeviceInfo = bluetoothClient.DiscoverDevices(10);
                comboBox1.DataSource = bluetoothDeviceInfo;
                comboBox1.DisplayMember = "DeviceName";
                comboBox1.ValueMember = "DeviceAddress";
                comboBox1.Focus();
                Cursor.Current = Cursors.Default;

        }

        private void btnConnect_Click(object sender, EventArgs e)
        {
            if (comboBox1.SelectedValue != null)
            {
                try
                {
                    bluetoothClient.Connect(new BluetoothEndPoint((BluetoothAddress)comboBox1.SelectedValue, service));
                    MessageBox.Show("Connected");
                }
                catch (Exception ex)
                {
                    MessageBox.Show(ex.Message);
                }
            }
        }


   private void btnSend_Click(object sender, EventArgs e)
        {

                    bluetoothClient.Connect(new BluetoothEndPoint((BluetoothAddress)comboBox1.SelectedValue, service));
                    String addr  = "112233445566";
                    Uri uri = new Uri("obex://"+@"SendTest.txt");
                    ObexWebRequest req= new ObexWebRequest(uri);

                    ObexWebResponse rsp;


        }

我找到了指南，但不太知道如何转换为 C#

' The host part of the URI is the device address, e.g. IrDAAddress.ToString(),
' and the file part is the OBEX object name.
Dim addr As String = "112233445566"
Dim uri As New Uri("obex://" & addr & "/HelloWorld2.txt")
Dim req As New ObexWebRequest(uri)
Using content As Stream = req.GetRequestStream()
   ' Using a StreamWriter to write text to the stream...
   Using wtr As New StreamWriter(content)
      wtr.WriteLine("Hello World GetRequestStream")
      wtr.WriteLine("Hello World GetRequestStream 2")
      wtr.Flush()
      ' Set the Length header value
      req.ContentLength = content.Length
   End Using
   ' In this case closing the StreamWriter also closed the Stream, but ...
End Using
Dim rsp As ObexWebResponse = CType(req.GetResponse(),ObexWebResponse) 
Console.WriteLine("Response Code: {0} (0x{0:X})", rsp.StatusCode)

Answer 1

和:

string fileName = @"SendTest.txt";

String adr = "0025677FB346";
Uri uri = new Uri("obex://" + adr + "/" + System.IO.Path.GetFileName(fileName)); 
ObexWebRequest request = new ObexWebRequest(uri);
request.ReadFile(fileName);

ObexWebResponse response = (ObexWebResponse)request.GetResponse();
MessageBox.Show(response.StatusCode.ToString());
response.Close();
