data（）;
}
public void data（）

SqlCommand cmd = new SqlCommand（select * from countrydetails，conn）;
SqlDataAdapter da = new SqlDataAdapter（cmd）;
DataSet ds = new DataSet（）;
da.Fill（ds）;
foreach（ds.Tables [0] .Rows中的DataRow行）
$
PieChart1.PieChartValues.Add（新的AjaxControlToolkit.PieChartValue
{
// PieChartValueColor =＃00b0f0，
// PieChartValueStrokeColor =＃676767，
Category = row [name]。ToString（），
Data = Convert.ToDecimal（row [value]）
}）;
}
