hi to all,

I want to How to two xml files data comaire and mitchmatch data show in excel file.

i am using this code

private void btnCompaire_Click(object sender, RoutedEventArgs e)
{
List fileslist = new List();
var list = new List>();
//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.
