推荐答案

我认为问题.Net Framework或文件夹权限问题。



1.应用程序池中的IIS是检查> Net Framework版本是配置和池是相同的。



2.另外你渲染PDF文件这个文件夹是每个人的用户和IIS_user persion这个folde



然后尝试

its i think issue .Net Framework or Folder Permission Issue.

1. IIS in Application pool are check >Net Framework version are config and pool are same.

2. other wise you render PDF file this folder are everyone user and IIS_user persion this folde

then try
