            //string[] finaltxtfiledata;
            // KeyValuePair finallist = new KeyValuePair();
            if (File.Exists(txtpath))
            {
                string[] LinesinText = File.ReadAllLines(txtpath);
                fileslist.Add(LinesinText[0]);
                fileslist.Add(LinesinText[1]);
            }
            string[] Linesin1 = File.ReadAllLines(fileslist[0]);
            string[] Linesin2 = File.ReadAllLines(fileslist[1]);
            bool areEqual = Linesin1pcfg.SequenceEqual(Linesin2pcfg);
            int onecount = Linesin1.Count();
            int twocount = Linesin2.Count();
            int finalcount;
            if (onecount > twocount)
            {
                finalcount = onecount;
            }
            else
            {
                finalcount = twocount;
            }
            if (!areEqual)
            {
                for (int i = 0; i < finalcount; i++)
                {
                    try
                    {
                        if (Linesin1pcfg[i] != null && Linesin2[i] != null)
                        {
                            if (Linesin1pcfg[i].Equals(Linesin2[i]))
                            {
                                //.Application oExcel = new Microsoft.Office.Interop.Excel.Application();
                                //Excel._Workbook oWorkBook;
                                //Excel._Worksheet oSheet;  
                                 Microsoft.Office.Interop.Excel.Application xlApp = new  Microsoft.Office.Interop.Excel.Application();
                                if (xlApp != null)
                                {
                                   // xlApp.Visible = true;
                                    
                                    string workbookPath = Linesin1[i];
                                     Microsoft.Office.Interop.Excel.Application excelApp = new  Microsoft.Office.Interop.Excel.Application();
                                     Microsoft.Office.Interop.Excel.Workbook excelWorkbook =  excelApp.Workbooks.Open(workbookPath);
                                     Microsoft.Office.Interop.Excel.Worksheet sheet =  excelWorkbook.Sheets["Sheet1"] as       Microsoft.Office.Interop.Excel.Worksheet;
                                    if (sheet == null) return;
                                    Microsoft.Office.Interop.Excel.Range range = sheet.get_Range("A1", Missing.Value);
                                    var yourValue = range.Text;
                                }
                            }
                            else
                            {
                                list.Add(new KeyValuePair(Linesin1[i], Linesin2[i]));
                            }
                        }
                    }
                    catch (Exception)
                    {
                        continue;
                    }
                }
            }
        }
 
 
 
 
In this code i am getting value :
xaml file path in TextFile  : like C:\Desktop\abc.xml
                                              C:\Desktop\xyz.xml
 
In Both files contaion some data like abc.xml file contaion 150 lines  & xyz.xml file contain 200 lines of xml code.
Getting data of both files 
  string[] Linesin1 = File.ReadAllLines(fileslist[0]);
  string[] Linesin2 = File.ReadAllLines(fileslist[1]);
 
Now i want to how to compaire data of both files and show in a EXCEL file.
Mismatch  xml data show on EXCEL file.
