Remarks
After calling MvCamCtrl.NET::MyCamera::MV_CC_OpenDevice_NET to connect to the device, you
can call this API to disconnect the device and release the resources.
Example
C#
using System;
using System.Runtime.InteropServices;
using System.IO;
using MvCamCtrl.NET;
namespace CloseDevice
{
class Program
{
static void Main(string[] args)
{
uint nTLayerType = MyCamera.MV_GIGE_DEVICE | MyCamera.MV_USB_DEVICE;
MyCamera.MV_CC_DEVICE_INFO_LIST stDevList = new MyCamera.MV_CC_DEVICE_INFO_LIST();
int nRet = MyCamera.MV_CC_EnumDevices_NET(nTLayerType, ref stDevList);
if (MyCamera.MV_OK != nRet)
{
Console.WriteLine("Enum device failed:{0:x8}", nRet);
return;
}
Console.WriteLine("The number of devices found: " + Convert.ToString(stDevList.nDeviceNum));
if (0 == stDevList.nDeviceNum)
{
return;
}
MyCamera.MV_CC_DEVICE_INFO stDevInfo;
//Change the device information structure pointer to device information structure
stDevInfo = (MyCamera.MV_CC_DEVICE_INFO)Marshal.PtrToStructure(stDevList.pDeviceInfo[0],
typeof(MyCamera.MV_CC_DEVICE_INFO));
MyCamera device = new MyCamera();
//Create device
nRet = device.MV_CC_CreateDevice_NET(ref stDevInfo);
if (MyCamera.MV_OK != nRet)
{
Console.WriteLine("Create device failed:{0:x8}", nRet);
return;
}
//Open device
device.MV_CC_OpenDevice_NET(MyCamera.MV_ACCESS_Exclusive,0);
if (MyCamera.MV_OK != nRet)
{
Console.WriteLine("Open device failed:{0:x8}", nRet);
