.aspx.cs代码如下：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
public partial class SQL___test : System.Web.UI.Page
{ string con = "server=localhost\\SQL2005 ;uid=sa;pwd=1111qq;database=userinfo";
SqlConnection conn;
SqlCommand cmd;
SqlDataReader datar;
string str_sql;
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btn_test_Click(object sender, EventArgs e)
{
conn = new SqlConnection(con);
conn.Open();
str_sql = txt_sql.Text;
cmd = new SqlCommand(str_sql, conn);
datar = cmd.ExecuteReader();
int i_fcount = datar.FieldCount;//字段数量
//构建表头
TableRow tr = new TableRow();
for (int i = 0; i < i_fcount; i++) {
TableCell td = new TableCell();
td.Text = datar.GetName(i);
tr.Cells.Add(td);
}
tbl_result.Rows.Add(tr);
//向表格里插入数据
while (datar.Read()) {
tr = new TableRow();
for (int i = 0; i < i_fcount; i++)
{
TableCell td = new TableCell();
td.Text = datar[i].ToString();
tr.Cells.Add(td);
}
tbl_result.Rows.Add(tr);
}
conn.Close();
}
}
效果如下：
