QuickBooks：未解决的 SDK 参考？

Question

当我构建示例 QuickBooks SDK 代码的 MCInvoiceAddQBFC C# 应用程序时，构建失败并显示

C:\Windows\Microsoft.NET\Framework\v2.0.50727\Microsoft.Common.targets : warning MSB3245: Could not resolve this reference. Could not locate the assembly "Interop.QBFC8, Version=8.0.0.28, Culture=neutral, PublicKeyToken=31d8aec643e18259". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors.

查看解决方案资源管理器，我看到有一个关于 Interop.QBFC8 的警告标志，它与构建输出中的第一条警告行一致。我确实安装了 SDK，我还尝试再次删除和添加引用。有什么想法吗？

Answer 1

您显然没有正确引用 DLL。我对 QuickBooks SDK 不熟悉，但如果您注意到您的 csc.exe 行，则没有对任何 QuickBooks dll 的引用。

您是否在解决方案的每个项目中添加了正确的引用？

编辑：当您从项目菜单中选择 Add reference... 时，Interop.QBFC 程序集是否列在 .NET 选项卡下?检查该文件是否存在。或者，通过浏览文件存在的路径显式添加对 DLL 的引用。您甚至可以先将 DLL 复制到您的项目文件夹中。

编辑： 引用 COM 接口会动态创建 Interop.XXX.dll。如果 QBFC8 作为 COM 引用添加，请确保您在 References 文件夹中看到它。您可能需要将using Interop.QBFC8; 更改为using QBFC8;。正如我所提到的，我注意到的第一件事是您的 csc.exe 行没有显示正确的引用。这是我用不同的 COM 引用构建项目时的一行：

C:\Windows\Microsoft.NET\Framework\v3.5\Csc.exe /noconfig /nowarn:1701,1702 errorreport:prompt /warn:4 /define:DEBUG;TRACE /reference:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\v3.5\System.Core.dll"
    /reference:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\v3.5\System.Data.DataSetExtensions.dll" 
    /reference:C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Data.dll 
    /reference:C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Deployment.dll 
    /reference:C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.dll

    /reference:C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Xml.dll 
    /reference:"C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework\v3.5\System.Xml.Linq.dll" 

    /reference:obj\Debug\Interop.COMSVCSLib.dll

    /debug+ /debug:full /filealign:512 /optimize- 
    /out:obj\Debug\WindowsFormsApplication1.exe 
    /resource:obj\Debug\WindowsFormsApplication1.Form1.resources 
    /resource:obj\Debug\WindowsFormsApplication1.Properties.Resources.resources /target:winexe
    Form1.cs Form1.Designer.cs Program.cs Properties\AssemblyInfo.cs Properties\Resources.Designer.cs Properties\Settings.Designer.cs

如果您没有看到 /reference:obj\Debug\Interop.XXX.dll，您需要再次查看您的参考资料。

我相信你需要添加对

的引用

C:\Program Files\Common Files\Intuit\QuickBooks\Interop.QBFC8.dll
