如何设置标签的货币格式

Question

我想显示两个标签的货币格式，像这样" 150,000,000,000 ">

这是我的代码

cn.Open();
cm = new SqlCommand("SELECT SUM(price*qty),SUM(buy_price*qty) FROM tblproduct", cn);
dr = cm.ExecuteReader();
while (dr.Read())
{
lblTprice.Text = dr[0].ToString();
lblTbuyPrice.Text = dr[1].ToString();

}
dr.Close();
cn.Close();

Answer 1

lblTprice.Text = dr[0].ToString("C", CultureInfo.CurrentCulture);
lblTbuyPrice.Text = dr[1].ToString("C", CultureInfo.CurrentCulture);
