每当我将我的 private void btnT_Click(object sender, EventArgs e)
{
SqlConnection cn = new SqlConnection("data source = TURKY-PC ; initial
catalog = coffeeshopDB ; integrated security = true ; ");
SqlCommand cmd;
SqlDataReader dr;
cmd = new SqlCommand("select SUM (cost) from billTB", cn);
cn.Open();
dr = cmd.ExecuteReader();
while (dr.Read())
{
btnT.Text = dr["cost"].ToString();
}
dr.Close();
cn.Close();
}
上传到 System.IndexOutOfRangeException: 'cost' 版本时，我都会得到一条标有我的 config.xml 的横幅>格式不正确...
该如何解决？
