c# - 使用 Rotativa 导致 'Could not load file or assembly' 错误

Question

我正在尝试在 MVC 应用程序(使用 Visual Studio 下载 NuGet 包)中使用 Rotativa 将 View 打印为 PDF，但每当调用该方法时，我都会收到“无法加载文件或程序集”错误。我试过在线寻找解决方案，但找不到合适的解决方案。以下是错误的完整堆栈跟踪:

Server Error in '/' Application.

以及我使用 Rotativa 的 ActionAsPDF 的代码示例:

[HttpGet]
public ActionResult ViewOrder(int id)
{
    Order GetOrder = new CartBL().GetOrderById(id);
    return View(GetOrder);
}

[HttpGet]
public ActionResult PrintOrder(int id)
{
    return new ActionAsPdf(
         "ViewOrder",
         new { id = id }) { FileName = "Order.pdf" };
}

如果有人能帮我解决这个问题，我将不胜感激。

Answer 1

我猜，Rotativa 可能是使用 ASP.NET MVC 构建的，并引用特定版本(即 System.Web.Mvc 版本 - 3.0.0.1)，并且您的 MVC 应用程序可能使用不同版本的 System. Web.Mvc。尝试在项目的 web.config 的 assemblyBinding 部分中添加类似于以下内容的程序集绑定(bind)。

  <dependentAssembly>
    <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35" />
    <bindingRedirect oldVersion="1.0.0.0-5.0.0.0" newVersion="5.0.0.0" />
  </dependentAssembly>

这里，您可能需要将5.0.0.0替换为您项目中System.Web.Mvc的版本。
