我在Windows 8上学习并尝试通过WiFi Direct在2台PC之间创建一个传输文件的应用程序。 现在我可以让应用程序在2台PC之间发送文本。Windows 8上的文件传输WiFi Direct
SendText：
private async void SendText()
{
string msg = SendMessageTextBox.Text;
if (msg.Length > 0)
{
var msgLength = dataWriter.MeasureString(msg);
dataWriter.WriteInt32(msg.Length);
dataWriter.WriteString(msg);
try
{
await dataWriter.StoreAsync();
Debug.WriteLine("Send Message >>: " + msg + "\n");
}
catch (Exception exc)
{
Debug.WriteLine("Send error: " + exc.Message + "\n");
}
}
}
接收文字：
private async void ReceiveText(StreamSocket socket, DataReader reader)
{
uint initialLength = 5;
try
{
await reader.LoadAsync(initialLength);
uint msgLength = (uint)reader.ReadInt32();
try
{
await reader.LoadAsync(msgLength);
string message = reader.ReadString(msgLength);
Debug.WriteLine(currentTime + " <<: " + message + "\n");
ReceiveText(socket, reader);
}
catch (Exception exc)
{
Debug.WriteLine("Error: " + exc.Message + "\n");
socket.Dispose();
}
}
catch (Exception exc)
{
Debug.WriteLine("Error: " + exc.Message + "\n");
socket.Dispose();
}
}
但是我真的搞不清如何转换和传输文件，我花很多时间在上面......
我知道有是DataReader和DataWriter类中的一些方法：
...
public IBuffer ReadBuffer(uint length);
public void ReadBytes(byte[] value);
public static DataReader FromBuffer(IBuffer buffer);
...
public void WriteBytes(byte[] value);
public void WriteBuffer(IBuffer buffer, uint start, uint count);
...
但如何将文件转换为流和使用什么方法发送和接收？
我尽我所能，但总是失败，真让我画画......
是否有人给我一些指导？还是一个小样本？
谢谢。
