the process cannot access the file because it is being used by another proce

问题出现情况：在新创建一个pdf文件后，前台下载文件时，出现了The process cannot access the file because it is being used by another process 这个问题

原因分析：在生成文件后，已经或关闭相关的文件流操作，但是在使用System.IO.File.OpenRead(fullPath)读取文件时，就出现了上述问题

解决：将读取文件的方式改成 var stream = new FileStream(fullPath, FileMode.Open, FileAccess.Read, FileShare.ReadWrite)问题解决
