table1 = GetDataTabletFromCSVFile(tbCSVPath.Text);  
table2 = GetDataTabletFromCSVFile1(tbCSVPath1.Text);
List<string> excludedNames = new List<string>();

        for (int i = 0; i < table1.Rows.Count; i++)
     {
          string col = table1.Rows[i]["Par Name"].ToString();

              if (!table2.Columns.Contains(col))
        {
              excludedNames.Add(col);
        }
      }
