    string connStr = ConfigurationManager.ConnectionStrings["shivcn"].ConnectionString;

    public String[] GetCurrancyrate(string exchangerate)
    {
        string rate="0";
        string symble="0";

        SqlConnection connection = new SqlConnection(this.connStr);
        connection.Open();
        SqlCommand command = new SqlCommand("select * from shiv.exchange_rate where country ='" + exchangerate + "'", connection);
        SqlDataReader reader = command.ExecuteReader();
        if (reader.Read())
        {
            rate = reader["rate"].ToString();
            symble = reader["symbol"].ToString();
        }
        connection.Close();
        connection.Dispose();
        reader.Close();
        reader.Dispose();
        command.Dispose();

        return new String[] { rate, symble };
    }
}

and I call This class
this.lblcurrency.Text = d.GetCurrancyrate(this.Session["exchangerate"].ToString())[0].ToString() ;
this.Lblcusymb1.Text = d.GetCurrancyrate(this.Session["exchangerate"].ToString())[1].ToString();

But It Fire Two Time

How I call This Class

Answer : get data from class

Of course it will fire 2 times. Because you are asking it to.

You need to put the result in a separate variable like this:

string[] currencies = d.GetCurrancyrate(this.Session["exchangerate"].ToString());

Then follow this by using:

this.lblcurrency.Text = currencies[0].ToString();
this.Lblcusymb1.Text = currencies[1].ToString();
