c# - 使用自定义字体的 RDLC 报告 - 调用 COM 组件已返回错误 HRESULT E_FAIL

Question

我有一个在 Windows Azure Web 角色上运行的 ASP.NET MVC(Razor View Engine 和 C#)应用程序。

我使用 RDLC 本地报告创建 pdf 文件，其中包含带有相应条形码的可打印价格标签。

使用启动任务安装条形码字体 (TrueType) 后，我让它在 Azure 上运行。最近，在我没有更改任何与此功能相关的内容的情况下，它就停止工作了。

我收到以下错误，到目前为止我还没有找到任何解决方案。我知道问题出在条形码字体上，因为 pdf 是使用 Arial 等标准字体生成的。此外，当在我的计算机上本地运行该应用程序时，它与条形码完美配合。

report.ReportPath = Server.MapPath("~/Reports/PriceTags.rdlc");

// Data source
report.DataSources.Add(new ReportDataSource("productsDataSet", dataset1));

// Some parameters
ReportParameterCollection reportParameters = new ReportParameterCollection();   
reportParameters.Add(new ReportParameter("currency", "EUR"));
reportParameters.Add(new ReportParameter("precision", 2));
report.SetParameters(reportParameters);

// FileContentResult GenPdf(LocalReport report, string filename)
return GenPdf(report, "Price Tags");

欢迎对此问题提供任何帮助，并对任何语法错误表示歉意。
