IEqualityComparer GethashCode method

Question

Hi,

My datatable contains the following columns...

    resultsView.Columns.Add("Fam.", typeof(string));
    resultsView.Columns.Add("Component", typeof(int));
    resultsView.Columns.Add("Description", typeof(string));
    resultsView.Columns.Add("Quantity", typeof(double));
    resultsView.Columns.Add("Unit", typeof(string));
    resultsView.Columns.Add("Unit Price", typeof(double));
    resultsView.Columns.Add("Total", typeof(double));

I have a datatable, I use IEqualityComparer to get distinct rows. Im able to get the distinct rows... What my problem is If i find same rows, i need to increase a columnValue in this datatable.

I mean i have column named "component" in my datatable, so if two rows are same, then i need to get one row with component value increased by 1 using IEqualitycomparer. What i get now is only one row with component column value not increased...

cud anyone plz help me to solve this problem??
