Sorting Months in ComboBox using C#

If u add month randomly and the try to fill combo box with that , the months will not be in order... to sort monthname take idea from below code:

string q = "select monthname from months"
datatable dtmonths = new datatable();
sqldataadapter sd = new sqldataadapter();
sd.Fill(dtmonths);

if (dtmonths.Rows.Count > 0)
{
    foreach(DataRow dr in dtmonths.Rows)
    {
        if (dr[0].ToString() == "January")
            cbmonthstd.Items.Add(dr[0].ToString());
    }
    foreach(DataRow dr in dtmonths.Rows)
    {
        if (dr[0].ToString() == "February")
            cbmonthstd.Items.Add(dr[0].ToString());
    }
    foreach(DataRow dr in dtmonths.Rows)
    {
        if (dr[0].ToString() == "March")
            cbmonthstd.Items.Add(dr[0].ToString());
    }
    foreach(DataRow dr in dtmonths.Rows)
    {
        if (dr[0].ToString() == "April")
            cbmonthstd.Items.Add(dr[0].ToString());
    }
    foreach(DataRow dr in dtmonths.Rows)
    {
        if (dr[0].ToString() == "May")
            cbmonthstd.Items.Add(dr[0].ToString());
    }
    foreach(DataRow dr in dtmonths.Rows)
    {
        if (dr[0].ToString() == "June")
            cbmonthstd.Items.Add(dr[0].ToString());
    }
    foreach(DataRow dr in dtmonths.Rows)
    {
        if (dr[0].ToString() == "July")
            cbmonthstd.Items.Add(dr[0].ToString());
    }
    foreach(DataRow dr in dtmonths.Rows)
    {
        if (dr[0].ToString() == "August")
            cbmonthstd.Items.Add(dr[0].ToString());
    }
    foreach(DataRow dr in dtmonths.Rows)
    {
        if (dr[0].ToString() == "September")
            cbmonthstd.Items.Add(dr[0].ToString());

    foreach(DataRow dr in dtmonths.Rows)
    {
        if (dr[0].ToString() == "October")
            cbmonthstd.Items.Add(dr[0].ToString());
    }
    foreach(DataRow dr in dtmonths.Rows)
    {
        if (dr[0].ToString() == "November")
            cbmonthstd.Items.Add(dr[0].ToString());
    }
    foreach(DataRow dr in dtmonths.Rows)
    {
        if (dr[0].ToString() == "December")
            cbmonthstd.Items.Add(dr[0].ToString());
