打开，关闭设备

首先添加引用：

using Jungo.wdapi_dotnet;
using Jungo.yourapp_lib;

获取PCI设备列表：

private YourApp_DeviceList pciDevList;//Declare PCI Device List
pciDevList = YourApp_DeviceList.TheDeviceList();//New
UInt32 dwStatus = pciDevList.Init();//Initilize Devices
if (dwStatus != (UInt32)WD_ERROR_CODES.WD_STATUS_SUCCESS)
    return;

将列表添加到ComBox中：

foreach (YourApp_Device dev in pciDevList)
    comboBox1.Items.Add(dev.ToString(true));
comboBox1.SelectedIndex = 0;

获取指定设备：

YourApp_Device device;
YourApp_Device dev = pciDevList.Get(comboBox1.SelectedIndex);

打开设备：

UInt32 dwStatus = device.Open();
if (dwStatus != (UInt32)WD_ERROR_CODES.WD_STATUS_SUCCESS)
{
    return false;
}

关闭设备：

bool bStatus = false;
if (device.Handle != IntPtr.Zero && !(bStatus = device.Close()))
{
    return false;
}
else
    device.Handle = IntPtr.Zero;
return bStatus;

获取PCI BAR，并添加到ComBox中：

string[] sBars = device.AddrDescToString(false);
 for (int i = 0; i < sBars.Length; ++i)
 {
     cmboBar.Items.Add(sBars[i]);
 }
 cmboBar.SelectedIndex = 0;
