Try this

private void GetExcelSheets(string FilePath, string Extension, string isHDR)
{
string conStr="";
switch (Extension)
{
    case ".xls": //Excel 97-03
        conStr = ConfigurationManager.ConnectionStrings["Excel03ConString"]
                 .ConnectionString;
        break;
    case ".xlsx": //Excel 07
        conStr = ConfigurationManager.ConnectionStrings["Excel07ConString"]
                 .ConnectionString;
        break;
}

//Get the Sheets in Excel WorkBoo
conStr = String.Format(conStr, FilePath, isHDR);
OleDbConnection connExcel = new OleDbConnection(conStr);
OleDbCommand cmdExcel = new OleDbCommand();
OleDbDataAdapter oda = new OleDbDataAdapter();
cmdExcel.Connection = connExcel;
connExcel.Open();

//Bind the Sheets to DropDownList
ddlSheets.Items.Clear(); 
ddlSheets.Items.Add(new ListItem("--Select Sheet--", ""));    
ddlSheets.DataSource=connExcel
         .GetOleDbSchemaTable(OleDbSchemaGuid.Tables, null);
ddlSheets.DataTextField = "TABLE_NAME";
ddlSheets.DataValueField = "TABLE_NAME";
ddlSheets.DataBind();
connExcel.Close();
txtTable.Text = "";
lblFileName.Text = Path.GetFileName(FilePath);
Panel2.Visible = true;
Panel1.Visible = false;
}
