Compare Word Documents c#

Question

 

Hi All,

 

I have to compare the text of two word documents using C#. These word documents contain images and text also. But I just wanted to compare the text.

 

Can anybody please let me know how to do this?

 

Thanks,

Ravi Mullick

I think that you must use Visual Studio Tools for Office.

See the simplest example. For VBA

Code Snippet

For a = 1 To Documents("doc1.doc").Words.Count

    Documents("doc1.doc").Words(a).Copy
    Documents("doc3.doc").Words(a).Paste
      
    If Documents("doc1.doc").Words(a).Text <> Chr(13) _
            And Documents("doc1.doc").Words(a).Text <> Chr(1) Then
        If Documents("doc1.doc").Words(a).Text <> Documents("doc2.doc").Words(a).Text Then _
            Documents("doc3.doc").Words(a).Font.Color = wdColorRed
    End If

object missing = System.Reflection.Missing.Value;

//create a readonly variable of object type and assign it to false.

object readonlyobj = false;

object filename = txtfile1.Text;

//create a word application object for processing the word file.

Word.Application app = new Word.ApplicationClass();

//create a word document object and open the above file..

Word.Document doc = app.Documents.Open(

ref filename, ref missing, ref readonlyobj, ref missing, ref missing,

ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);

string filenm = txtfile2.Text;

string nm = txtpath.Text + @"\" + getfilename(txtfile1.Text);

object filesavename = nm;

doc.SaveAs(ref filesavename, ref missing, ref missing, ref missing, ref missing, ref missing,

ref missing, ref missing, ref missing, ref missing, ref missing);

doc.TrackRevisions = true;

doc.ShowRevisions = true;

doc.PrintRevisions = true;

doc.Compare(filenm);

doc.Close(ref missing, ref missing, ref missing);

app.Quit(ref missing, ref missing, ref missing);

MessageBox.Show("Process complete");

Hi,

I have used the below code and it is working for me for saving the compared document.

    public class WordDocComparer
    {
        #region Variables
        private Microsoft.Office.Interop.Word.Application WordApp;
        private Document aDoc;
        string _sourceFilePath;
        string _destinationFilePath;
        #endregion

        #region Constructor
        /// <summary>
        /// This is the constructor for WordDocComparer
        /// </summary>
        public WordDocComparer(string source, string destination)
        {
            _sourceFilePath = source;
            _destinationFilePath = destination;
        }
        #endregion

        #region Public Methods
        public void Compare()
        {
            object missing = System.Reflection.Missing.Value;

            object readonlyobj = false;
            object filename = _sourceFilePath;

            //create a word application object for processing the word file.
            Microsoft.Office.Interop.Word.Application app = new Microsoft.Office.Interop.Word.Application();

            //create a word document object and open the above file..
            Document doc = app.Documents.Open(ref filename, ref missing, ref readonlyobj, ref missing, ref missing
                , ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);

            doc.TrackRevisions = true;
            doc.ShowRevisions = true;
            doc.PrintRevisions = true;
            doc.Compare(_destinationFilePath, missing, WdCompareTarget.wdCompareTargetNew, true, false, false, false, false);

            doc.Close(ref missing, ref missing, ref missing);
            app.Quit(ref missing, ref missing, ref missing);
            MessageBox.Show("Process complete");
        }
        #endregion

        #region Private Method
        #endregion
    }

Thanks and Regards.
