  • Hi Özlem,

    I tested your code and it was a success on my machine. Could you provide more detailed information? For example, error messages(English). 

    You could use the following code to get the number of open Word documents:
    Microsoft.Office.Interop.Word.Application WordObj;
    WordObj = (Microsoft.Office.Interop.Word.Application)System.Runtime.InteropServices.Marshal.GetActiveObject("Word.Application");
    // The count variable is the number of open Word documents
    int count = WordObj.Windows.Count;

    You could refer to the following  link:
    C# Get list of opened Word documents

    Best Regards,
