ajax 数据库中随机读取5条数据动态在页面中刷新

for (int i = 0; i < n; i++)
{
string username = mytable.Rows[i]["username"].ToString();
string fullname = mytable.Rows[i]["FullName"].ToString();
string email = mytable.Rows[i]["Email"].ToString();
if (i % 2 != 0)
{
str.Append("<tr><td>" + username + "</td>");
str.Append("<td>" + fullname + "</td>");
str.Append("<td>" + email + "</td></tr>");
}
else
{
str.Append("<tr style='color:blue'><td>" + username + "</td>");
str.Append("<td>" + fullname + "</td>");
str.Append("<td>" + email + "</td></tr>");
}
}
str.Append("</table>");
Response.Clear();
Response.ContentType = "application/text";
Response.Write(str);
Response.End();
