How to Determine If a Word Document Is Read-Only?

Question

I use Word.Interop to work with Word Document and let user to open a file from hard disk.

Sometimes I get error saying that the file that user has chosen is readonly.

How can I check if a file is readonly or not?

Are you sure you are actually talking about the File attribute (that can be set via the Windows file properties dialog)? If so, you can use FileInfo.IsReadOnly:

FileInfo fileInfo = new FileInfo(@"path\to\file");
if (fileInfo.IsReadOnly)
{
    // do something
}

otherwise, refer to this answer if another process is using the file.

Word documents can be marked read only while the file itself is totally normal. – Shadow Wizard Says No More War Aug 12 '12 at 08:34
