UsbBulkOutPipe.OutputStream 属性

定义

命名空间:

Windows.Devices.Usb

获取一个输出流，应用可以将要发送到终结点的数据写入该流。

public:
 property IOutputStream ^ OutputStream { IOutputStream ^ get(); };

IOutputStream OutputStream();

public IOutputStream OutputStream { get; }

var iOutputStream = usbBulkOutPipe.outputStream;

Public ReadOnly Property OutputStream As IOutputStream

属性值

IOutputStream

包含传输数据的输出蒸汽。

注解

若要写入数据，请先使用 OutputStream 属性从管道获取输出流，然后使用 DataWriter 对象写入实际缓冲区。

Windows::Storage::Streams::Buffer^ buffer = ref new Windows::Storage::Streams::Buffer(TRANSFER_SIZE);  

buffer->Length = TRANSFER_SIZE;  

auto stream = DeviceList::Current->Fx2Device->Configuration->UsbInterfaces->GetAt(0)->BulkOutPipes->GetAt(0)->OutputStream;  

Windows::Storage::Streams::DataWriter^ writer = ref new Windows::Storage::Streams::DataWriter(stream);  

writer->WriteBuffer(buffer);  


});
