在LibUsbSharp中進(jìn)行異步數(shù)據(jù)傳輸可以通過(guò)使用異步方法或事件來(lái)實(shí)現(xiàn)。下面是使用異步方法進(jìn)行異步數(shù)據(jù)傳輸?shù)氖纠a:
using LibUsbDotNet;
using LibUsbDotNet.Main;
class Program
{
static UsbDevice MyUsbDevice;
static void Main(string[] args)
{
UsbDeviceFinder finder = new UsbDeviceFinder(1234, 5678); // Vendor ID and Product ID
MyUsbDevice = UsbDevice.OpenUsbDevice(finder);
if (MyUsbDevice == null)
{
throw new Exception("Device not found");
}
MyUsbDevice.Open();
byte[] buffer = new byte[64];
IAsyncResult result = MyUsbDevice.BeginBulkWrite(buffer, 1000, null, null);
// Do other stuff while data transfer is in progress
int bytesTransferred = MyUsbDevice.EndBulkWrite(result);
MyUsbDevice.Close();
}
}
在上面的示例代碼中,我們通過(guò)調(diào)用BeginBulkWrite
方法開(kāi)始了一個(gè)異步數(shù)據(jù)傳輸操作。在數(shù)據(jù)傳輸操作進(jìn)行的同時(shí),我們可以做一些其他的操作。最后,我們通過(guò)調(diào)用EndBulkWrite
方法來(lái)獲取傳輸?shù)淖止?jié)數(shù),并完成數(shù)據(jù)傳輸操作。
另外,LibUsbSharp也提供了一些異步事件用于數(shù)據(jù)傳輸,你可以注冊(cè)這些事件來(lái)處理異步數(shù)據(jù)傳輸。以下是一個(gè)使用異步事件進(jìn)行數(shù)據(jù)傳輸?shù)氖纠a:
using LibUsbDotNet;
using LibUsbDotNet.Main;
class Program
{
static UsbDevice MyUsbDevice;
static void Main(string[] args)
{
UsbDeviceFinder finder = new UsbDeviceFinder(1234, 5678); // Vendor ID and Product ID
MyUsbDevice = UsbDevice.OpenUsbDevice(finder);
if (MyUsbDevice == null)
{
throw new Exception("Device not found");
}
MyUsbDevice.Open();
byte[] buffer = new byte[64];
MyUsbDevice.DataReceived += (sender, e) =>
{
int bytesTransferred = e.Count;
// Handle received data
};
MyUsbDevice.DataSent += (sender, e) =>
{
int bytesTransferred = e.Count;
// Handle sent data
};
MyUsbDevice.Write(buffer, 1000);
// Do other stuff while data transfer is in progress
MyUsbDevice.Close();
}
}
在上面的示例代碼中,我們通過(guò)注冊(cè)DataReceived
和DataSent
事件來(lái)處理接收和發(fā)送數(shù)據(jù)的異步操作。當(dāng)數(shù)據(jù)傳輸完成時(shí),這些事件會(huì)被觸發(fā),我們可以在事件處理程序中處理接收和發(fā)送的數(shù)據(jù)。
希望以上信息能幫助到你。如果有任何疑問(wèn),請(qǐng)隨時(shí)提出。
