我有一个ASP.NET MVC 5应用程序。它有一个简单的形式,当用户提交它时,表单存储在缓存中,然后调用另一个控制器动作,该操作将以PDF的形式返回模型作为视图。
我没有必要在本地保存它,只是在浏览器中显示,以便用户可以下载它。
也不需要数据库,这就是为什么我将模型存储在缓存中。
在本地,在Visual Studio 2013上,它工作正常。但是当我发布到IIS 7时,我会收到一个未处理的执行错误。这是我收回的堆栈跟踪:

我第一次使用ActionAsPDF(),但是现在我也尝试使用返回新的ViewAsPDF()。两者都提供相同的错误和堆栈跟踪。这是否必须执行某些权限?
解决方法
此错误是一个名为(MSVCP120.dll)的Visual Studio 2013文件缺少的C可重新分发包。
解决问题:
>打开Visual Studio 2013的可下载C包可下载链接如下:
download Visual C++ Redistributable Packages for Visual Studio 2013
>单击下载并选择文件(vcredist_x86.exe),即使您正在运行X64位服务器版本。
>安装文件。
