fees_structure
有 24 个“A”类别行。但是当我尝试获取它们并打印时,它只显示 20 或(有时是 21 行)
这是我的代码:
string catA = "SELECT id,fees_name,amount,fee_category FROM fees_structure where fee_category='A' ORDER BY id";
using (SqlCommand scom = new SqlCommand(catA, con))
{
using (SqlDataReader read = scom.ExecuteReader())
{
read.Read();
if (read.HasRows)
{
while (read.Read())
{
feestableA.Append("<tr>");
feestableA.Append("<td>" + read["fees_name"] + "</td>");
feestableA.Append("<td>" + read["amount"] + "</td>");
feestableA.Append("</tr>");
}
plcfeesA.Controls.Add(new Literal { Text = feestableA.ToString() });
plcfeesA.Dispose();
}
}
}
