Question

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

C:\Windows\Microsoft.NET\Framework\v2.0.50727\Microsoft.Common.targets : warning MSB3245: Could not resolve this reference.

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的警告信号，它与构建输出中的第一个警告线一致。我确实安装了SDK，我也尝试删除并再次添加引用。有什么想法吗？

您显然没有正确引用DLL。我不熟悉QuickBooks SDK，但如果您注意到 csc.exe 行，则不会引用任何QuickBooks dll。

您是否在解决方案的每个项目中添加了适当的引用？

编辑：当您从项目菜单中选择添加参考... 时，是否在 .NET 标签下列出了Interop.QBFC程序集？检查文件是否存在。或者，通过浏览到文件所在的路径，显式添加对DLL的引用。您甚至可以先将DLL复制到项目文件夹中。

编辑：引用COM接口会动态创建Interop.XXX.dll。如果将QBFC8添加为COM引用，请确保在References文件夹中看到它。您可能需要将using Interop.QBFC8;更改为using QBFC8;。我注意到的第一件事就是我提到的 csc.exe 行没有显示正确的引用。以下是使用不同的COM引用构建项目时的行：

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.Drawing.dll 
    /reference:C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Windows.Forms.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，则需要再次查看参考文献。

我相信您需要添加对

的引用

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