asp.net-mvc-4 – NReco.PdfGenerator服务器上的管道已经结束错误

我正在为我的PDF文档使用 NReco.PdfGenerator(该组件基于WkHtmlToPdf工具),我的代码允许我使用参数controller,action,model创建一个调用函数的pdf：

public static byte[] GeneratePdfDocument(System.Web.Mvc.Controller controller,string viewName,object model)
{
     string result;
     controller.ViewData.Model = model;
     using (StringWriter sw = new StringWriter())
     {
         ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(controller.ControllerContext,viewName);
         ViewContext viewContext = new ViewContext(controller.ControllerContext,viewResult.View,controller.ViewData,controller.TempData,sw);
         viewResult.View.Render(viewContext,sw);

         result = sw.ToString();
     }

     return (new NReco.PdfGenerator.HtmlToPdfConverter()).GeneratePdf(result);
}

使用此代码,我可以从我的视图中轻松创建PDF,并且它在我的开发环境中运行良好但在服务器上我收到此错误：

The pipe has been ended.

我认为这可能是我的IIS上的权限或某些配置的问题,任何想法？

解决方法

您可能缺少VS2013(x86)的Visual C Redistributable Packages.即使您的服务器运行的是64位Windows,也需要安装x86 C软件包.
