LoadData();
}
}
private void LoadData()
{
string constr = "data source=LOVE-PC\SQLEXPRESSPC;initial catalog=BoKe;user id=sa;password=admin";
using (SqlConnection conn = new SqlConnection(constr))

SqlDataAdapter adapter = new SqlDataAdapter(cmd);
DataTable dt = new DataTable();
adapter.Fill(dt);
StringBuilder sb = new StringBuilder();
sb.Append("<ul>");
for (int i = 0; i < dt.Rows.Count; i++)
{
sb.Append("<a href="http://www.gimoo.net/t/1903/ + dt.Rows[i]["BigImgUrl"] + ">");//添圖片路徑
sb.Append("<li>");
sb.Append("<img src="http://www.gimoo.net/t/1903/ + dt.Rows[i]["SmallImgUrl"] + ">");//添圖片路徑

sb.Append("</a>");
}
sb.Append("</ul>");
mydiv.InnerHtml = sb.ToString();
}
}
