Question

我是POS系统的新手，所以如果我错过任何信息让我知道将用它编辑。我已经通过设置在其他PC上安装了WINFORM，我希望在表单加载时顶部打开一个现金抽屉。我使用过Microsoft.PointOfService dll。继承了我的代码：

  public partial class CashRegister : Form
{


    CashDrawer myCashDrawer;
    PosExplorer explorer;

    public CashRegister()
    {
        InitializeComponent();
        explorer = new Microsoft.PointOfService.PosExplorer();
        DeviceInfo ObjDevicesInfo = explorer.GetDevice("CashDrawer", "EP-125k");
        //myCashDrawer = (CashDrawer) explorer.CreateInstance(ObjDevicesInfo);
       // myCashDrawer.OpenDrawer();
    }
    public void OpenCashDrawer()
    {
        myCashDrawer.Open();
        myCashDrawer.Claim(1000);
        myCashDrawer.DeviceEnabled = true;
        myCashDrawer.OpenDrawer();
        myCashDrawer.DeviceEnabled = false;
        myCashDrawer.Release();
        myCashDrawer.Close();
    }

    private void button1_Click(object sender, EventArgs e)
    {
        this.Close();
    }

    private void CashRegister_Load(object sender, EventArgs e)
    {
      //  myCashDrawer.OpenDrawer();
    }
}

但是当它执行时会出现以下错误：

类型初始化程序'Microsoft.PointOfService.Management.Explorer'抛出异常

任何人都可以提供帮助。

我已经向你们所有人表示感谢，这只是一个愚蠢的错误。安装.Net v1.12.exe的POS并且没有任何错误。
