蓝牙发送文件 [英] bluetooth file send
本文介绍了蓝牙发送文件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我是新的蓝牙开发，我发现32netfeet。现在，我可以到附近搜索蓝牙设备并连接到他们，但我如何发送文件例如SendTest.txt？我试着ButtonClick事件使用OBEX，但我不明白这是我的例子code：
使用InTheHand.Net;
使用InTheHand.Net.Sockets;
使用InTheHand.Net.Bluetooth;命名空间BluetoothIntheHand
{
公共部分类窗体2：表
{
私人的Guid =服务BluetoothService.DialupNetworking;
私人BluetoothClient bluetoothClient; 公共窗体2（）
{
的InitializeComponent（）;
} 私人无效btnSearch_Click（对象发件人，EventArgs的发送）
{ BluetoothRadio.PrimaryRadio.Mode = RadioMode.Discoverable;
BluetoothRadio myRadio = BluetoothRadio.PrimaryRadio;
lblSearch.Text =+ myRadio.LocalAddress.ToString（）; bluetoothClient =新BluetoothClient（）;
Cursor.Current = Cursors.WaitCursor;
BluetoothDeviceInfo [] bluetoothDeviceInfo = {};
bluetoothDeviceInfo = bluetoothClient.DiscoverDevices（10）;
comboBox1.DataSource = bluetoothDeviceInfo;
comboBox1.DisplayMember =设备名称;
comboBox1.ValueMember =DeviceAddress;
comboBox1.Focus（）;
Cursor.Current = Cursors.Default; } 私人无效btnConnect_Click（对象发件人，EventArgs的发送）
{
如果（comboBox1.SelectedValue！= NULL）
{
尝试
{
bluetoothClient.Connect（新BluetoothEndPoint（（BluetoothAddress）comboBox1.SelectedValue，服务））;
MessageBox.Show（已连接）;
}
赶上（异常前）
{
MessageBox.Show（ex.Message）;
}
}
}
私人无效btnSend_Click（对象发件人，EventArgs的发送）
{ bluetoothClient.Connect（新BluetoothEndPoint（（BluetoothAddress）comboBox1.SelectedValue，服务））;
字符串地址=112233445566;
开放的我们的uri =新的URI（OBEX：//+ @SendTest.txt）;
ObexWebRequest REQ =新ObexWebRequest（URI）; ObexWebResponse RSP;
}
我找到了指南，但真的不知道如何转换为C＃
URI的主机部分是设备地址，例如IrDAAddress.ToString（），
'和文件部分是OBEX对象名称。
昏暗地址作为字符串=112233445566
昏暗URI作为新的URI（OBEX：//＆放大器;地址＆安培;/HelloWorld2.txt）
昏暗的REQ作为新ObexWebRequest（URI）
使用内容作为流= req.GetRequestStream（）
使用的StreamWriter写入文本流中...
使用WTR作为新的StreamWriter（内容）
wtr.WriteLine（的Hello World GetRequestStream）
wtr.WriteLine（的Hello World GetRequestStream 2）
wtr.Flush（）
设定长度标头值
req.ContentLength = content.Length
使用完
在这种情况下，关闭的StreamWriter还关闭了流，但...
使用完
昏暗RSP作为ObexWebResponse = CTYPE（req.GetResponse（），ObexWebResponse）
Console.WriteLine（响应code：{0}（0X {0：X}），rsp.Status code）
解决方案
// URI的主机部分是设备地址，例如IrDAAddress.ToString（），
//和文件部分是OBEX对象名称。{
字符串地址=112233445566;
开放的我们的uri =新的URI（OBEX：//+地址+/HelloWorld2.txt）;
ObexWebRequest REQ =新ObexWebRequest（URI）;
使用（流内容= req.GetRequestStream（））{
//使用的StreamWriter写入文本流中...
使用（WTR的StreamWriter =新的StreamWriter（内容））{
wtr.WriteLine（的Hello World GetRequestStream）;
wtr.WriteLine（的Hello World GetRequestStream 2）;
wtr.Flush（）;
//设置长度标头值
req.ContentLength = content.Length;
}
}
//在这种情况下关闭的StreamWriter还关闭了流，但...
ObexWebResponse RSP =（ObexWebResponse）req.GetResponse（）;
Console.WriteLine（响应code：{0}（0X {0：X}），rsp.Status code）;
}
i'm new to bluetooth development and i found the 32netfeet . Right now i'm able to search for bluetooth devices nearby and connect to them but how do i send a file e.g SendTest.txt? I tried buttonclick event using the OBEX but i don't understand this is my example code:
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;
}
I found the guide but don't really know how to convert to 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)
解决方案
// The host part of the URI is the device address, e.g. IrDAAddress.ToString(),
// and the file part is the OBEX object name.
{
string addr = "112233445566";
Uri uri = new Uri("obex://" + addr + "/HelloWorld2.txt");
ObexWebRequest req = new ObexWebRequest(uri);
using (Stream content = req.GetRequestStream()) {
// Using a StreamWriter to write text to the stream...
using (StreamWriter wtr = 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;
}
}
// In this case closing the StreamWriter also closed the Stream, but ...
ObexWebResponse rsp = (ObexWebResponse)req.GetResponse();
Console.WriteLine("Response Code: {0} (0x{0:X})", rsp.StatusCode);
}
