Refer: Reading Excel files from C#

To connect to an excel file you need the appropriate connection string:

string connString = @"Provider=Microsoft.ACE.OLEDB.12.0; Data Source=<YourExcelPath>;
Extended Properties=\"Excel 12.0;HDR=YES;\"";

After use the OleDb classes to query the information from the file:

string selectCmd = "SELECT * FROM <SheetName>";

using(OleDbConnection excelConn = new OleDbConnection(connString))
{
    excelConn.Open(); 
    OleDbCommand command = new OleDbCommand(selectCmd, excelConn);
    OleDbDataAdapter da = new OleDbDataAdapter(command);

    DataTable sheetInfo = new DataTable();
    dataAdapter.Fill(sheetInfo);

    //Do something with the data.
    Bind your control with this datatable here
}

So you need to replace “YourExcelPath” with the path of your excel file..
