C# Word到PDf转换的PDf有错误-拒绝访问错误

将MS word文档转换为PDF后。如果我发送相同路径的已转换word到pdf。i、 e PDF。在提取文件时，在服务器上发布网站时，我会遇到访问被拒绝的错误。它在本地计算机上工作。是否有我在代码中留下的东西，或者是否有我需要安装的东西

您是否检查了用户在发出错误的机器上的权限（以确保他们具有所需的读/写权限）？

您可以发布异常的stacktrace吗？我不明白为什么这个答案被否决。我对它投了更高的票，因为这是一个很好的反问（但也许它应该被添加为一个评论）。我很确定“拒绝访问”警告与权限有关。文件被锁定，或者Web服务器以无法访问该文件的用户身份运行。谢谢Bruno.：）我想发表评论，但由于没有足够的声誉，无法发表评论！所以，我不得不这样做作为一个答案…我已经改变了服务器。以同样的权限，现在它的工作良好。在一个或多个服务器中具有相同权限，但它不工作。
