mscorlib.dll中的兄弟QL-700 B-PAC SDK错误'System.IO.FileNotFoundException'

Question

我有Brother QL-700标签打印机，我已经安装了上个月底发布的最新B-PAC SDK V3.2.001 64位。我也在我的Windows 10 64位计算机上安装了“B-PAC客户端组件”。给定模板文件（addr.LBX）从P-touch Editor 5.2成功打印。

但是B-Pac sdk会从C＃程序下面打印出来。执行给定的代码片段时，它会给出以下错误

'NamePlt.vshost.exe' (CLR v2.0.50727: NamePlt.vshost.exe): Loaded 'C:\Program Files\Brother bPAC3 SDK\Samples\VCS\NamePlt\bin\Debug\Interop.bpac.dll'. Module was built without symbols.Exception thrown: 'System.IO.FileNotFoundException' in mscorlib.dll

任何支持都非常感谢！

private const string TEMPLATE_DIRECTORY = @"C:\Program Files\Brother bPAC3 SDK\Templates\"; // Template file path
private const string TEMPLATE_FILE = "addr.LBX";    // Template file printing fine from the P-touch Editor

    public Form1()
    {
        InitializeComponent();
    }

    private void btnPrint_Click(object sender, EventArgs e)
    {
        string templatePath = TEMPLATE_DIRECTORY;

        templatePath += TEMPLATE_FILE;

        bpac.DocumentClass doc = new DocumentClass();
        if (doc.Open(templatePath) != false)
        {
            //doc.GetObject("objCompany").Text = txtCompany.Text;
            //doc.GetObject("objName").Text = txtName.Text;

            // doc.SetMediaById(doc.Printer.GetMediaId(), true);
            doc.StartPrint("", PrintOptionConstants.bpoDefault);
            doc.PrintOut(1, PrintOptionConstants.bpoDefault);
            doc.EndPrint();
            doc.Close();

            MessageBox.Show("Error code : " + doc.ErrorCode);

        }
        else
        {
            MessageBox.Show("Open() Error: " + doc.ErrorCode);
        }
    }
