Put the all Excel files in one folder in your application
Add one link on your page like

<asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl="~/Images/02639_SandeepSureshAkhare_BFSI_Self Appraisal.xls" Target=_self>HyperLink</asp:HyperLink></td>

and open it i think this one of the simplest way to open any file
The other is COM object which makes your application bulky

Thanks and Regards

Please Import Microsoft Excel from the COM Tab of the Add Reference Page.

See if this code helps U.
Try to understand this and write Ur code accordingly.

Create a table in the webpage.
Add the rows and its contents dynamically by iterating through the corresponding object.

Excel.Workbook objWorkBook = ExcelObj.Workbooks.Open("d:\\one.xls", 0, true, 5,
"", "", true, Excel.XlPlatform.xlWindows, "\t", false, false, 0, true);

Excel.Sheets sheets = objWorkBook.Worksheets;

Excel.Worksheet objworksheet = (Excel.Worksheet)sheets.get_Item(1);

Excel.Range objRange = objworksheet.get_Range("A" + i, "J" + i);
System.Array objvalues = (System.Array)objRange.Cells.Value;
string[] strArray = ConvertToStringArray(objvalues);

//Code to add data to the existing cells

using Excel = Microsoft.Office.Interop.Excel;

Microsoft.Office.Interop.Excel.Application excel = null;
Microsoft.Office.Interop.Excel.Workbook xls = null;
excel = new Microsoft.Office.Interop.Excel.Application();
object missing = Type.Missing;
object trueObject = true;
excel.Visible = false;

int i = 1;
while (wsEnumerator.MoveNext())
{
Microsoft.Office.Interop.Excel.Worksheet wsCurrent = Convert.ToString(Microsoft.Office.Interop.Excel.Worksheet.ReferenceEquals);
String outputFile = strFilePath + "." + i.ToString() + ".html";
wsCurrent.SaveAs(outputFile, format, missing, missing, missing,
missing, missing, missing, missing, missing);

I think that the & is an xml reserved character, you must use the entity form like this & amp ; (without the spaces).

Hello Friends,

I am encrypting an string and passing it with URL,

But when it is decrypted it is creating the following error :

System.FormatException: Invalid length for a Base-64 char array. at System.Convert.FromBase64String(String s)

but its working fine on local.

I have noticed one thing that which encrypted string is having '+' in it only that encrypted string creating this error while decrypting online.

And same encryped string is decrypted on local it is working fine...

I am not able to understand why it is happening.

In .Net, the method you're looking for is this one: System.Web.HttpUtility.UrlEncode().

Hope this helps,
