SqlDataAdapter adapter = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();

StringBuilder sb = new StringBuilder();
sb.Append("<ul>");
for (int i = 0; i < dt.Rows.Count; i++)
{
sb.Append("<a href=" + dt.Rows[i]["BigImgUrl"] + ">");//添图片路径
sb.Append("<li>");
sb.Append("<img src=" + dt.Rows[i]["SmallImgUrl"] + ">");//添图片路径
