将从数据库中获取的数据 ，以HTML表格的形式显示
1.HTML页面
<body> <form id="form1" runat="server"> <div id="divUsers" runat="server"> </div> </form> </body>
2.添加命名空间
using System.Configuration; using System.Data.SqlClient; using System.Data; using System.Text;
3. 在Page_Load事件里面加载表格
protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) { string conString = ConfigurationManager.ConnectionStrings["DemosDatabaseConnectionString"].ConnectionString; string query = "SELECT * FROM Customers"; using (SqlConnection con = new SqlConnection(conString)) { using (SqlCommand cmd = new SqlCommand(query)) { using (SqlDataAdapter sda = new SqlDataAdapter()) { cmd.Connection = con; sda.SelectCommand = cmd; using (DataTable dt = new DataTable()) { sda.Fill(dt); StringBuilder str = new StringBuilder(); StringBuilder str1 = new StringBuilder(); str.Append("<table>"); str.Append("<tr>"); for (int k = 0; k < dt.Columns.Count; k++) { str.Append("<th>"); str.Append(dt.Columns[k].ColumnName); str.Append("</th>"); } str.Append("<th>"); str.Append(""); str.Append("</th>"); str.Append("</tr>"); for (int i = 0; i < dt.Rows.Count; i++) { str.Append("<tr>"); for (int k = 0; k < dt.Columns.Count; k++) { str.Append("<td>"); str.Append(dt.Rows[i][k]); str.Append("</td>"); } str.Append("<td>"); str.Append("<input type='text' ID='txtId" + (i + 1) + "' runat='server' />"); str.Append("</td>"); str.Append("</tr>"); } str.Append("</table>"); str.Append("<table>"); str.Append("<tr>"); for (int k = 0; k < dt.Columns.Count; k++) { str.Append("<th>"); str.Append("Head"); str.Append("</th>"); } str.Append("</tr>"); for (int i = 0; i < dt.Rows.Count; i++) { str.Append("<tr>"); for (int k = 0; k < dt.Columns.Count; k++) { str.Append("<td>"); str.Append("Test"); str.Append("</td>"); } str.Append("</tr>"); } str.Append("</table>"); divUsers.InnerHtml = str.ToString(); } } } } } }
