注意：
临时文件夹读写权限设置：1.自己设置
2.通过代码控制
//给Excel文件添加"Everyone,Users"用户组的完全控制权限
FileInfo fi = new FileInfo(excelPath);
System.Security.AccessControl.FileSecurity fileSecurity = fi.GetAccessControl();
fileSecurity.AddAccessRule(new FileSystemAccessRule("Everyone", FileSystemRights.FullControl, AccessControlType.Allow));
fileSecurity.AddAccessRule(new FileSystemAccessRule("Users", FileSystemRights.FullControl, AccessControlType.Allow));
fi.SetAccessControl(fileSecurity); //给Excel文件所在目录添加"Everyone,Users"用户组的完全控制权限
DirectoryInfo di = new DirectoryInfo(Path.GetDirectoryName(excelPath));
System.Security.AccessControl.DirectorySecurity dirSecurity = di.GetAccessControl();
dirSecurity.AddAccessRule(new FileSystemAccessRule("Everyone", FileSystemRights.FullControl, AccessControlType.Allow));
dirSecurity.AddAccessRule(new FileSystemAccessRule("Users", FileSystemRights.FullControl, AccessControlType.Allow));
di.SetAccessControl(dirSecurity);
