Question

my code :

 object c = "d:\\1.doc";

        if(File.Exists(c.ToString()))
        {
            File.Delete(c.ToString());
        }

error :

The process cannot access the file ‘d:\1.doc’ because it is being used
by another process.

How close ? with code

Answer 1

first of all use string instead of object, so:

string c = "d:\\1.doc";

now as the message indicated the file being used by another process. either by windows process, or you are opening the file stream and forget to close it. check in your code where you are interacting with the file.

Edit: Since you are using Microsoft.Office.Interop.Word make sure you close the file(s) open first like:

Word.ApplicationClass word = new Word.ApplicationClass();

//after using it:

if (word.Documents.Count > 0)
{
    word.Documents.Close(...);
}

((Word._Application)word.Application).Quit(..);

word.Quit(..);
