推荐答案

文件无法打开可能有以下几种原因：



1.您的系统没有安装.pdf查看器（如Adobe的Acrobat Reader），并且您已禁用Chrome中的默认.pdf阅读器：[ ^ ]。



2. the文件名不正确。



3.特定的.pdf文件已被锁定，加密，或者您无权打开它。



有关在WinForms中显示.pdf的各种技术，请参阅：[ ^ ]。

There could be several reasons why the file will not open:

1. your system has no .pdf viewer installed (like Adobe's Acrobat Reader), and you have the default .pdf reader in Chrome disabled: [^].

2. the file name is incorrect.

3. the specific .pdf file is locked, encrypted, or you don't have permission necessary to open it.
