怎样在.NET中执行SQL语句,并把结果查返回显示在WEB面面中(不知哪错了,新人求指教)
备注:假设已经有一个名为sqlConnection1的SqlConnection

using System;
using System.Collections;
using System.ComponentModel;
using System.Data.SqlClient;
using System.Drawing;
using System.Web;
using System.Web.SessionState;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;

namespace WebApplication6
{
/// <summary>
/// WebForm1 的摘要说明。
/// </summary>
public class WebForm1 : System.Web.UI.Page
{
protected System.Web.UI.WebControls.Label Label1;
protected System.Data.SqlClient.SqlConnection sqlConnection1;
protected System.Data.SqlClient.SqlCommand sqlCommand1;
protected System.Web.UI.WebControls.Button Button1;

private void Page_Load(object sender, System.EventArgs e)
{
// 在此处放置用户代码以初始化页面
}

#region Web 窗体设计器生成的代码
override protected void OnInit(EventArgs e)
{
//
// CODEGEN: 该调用是 ASP.NET Web 窗体设计器所必需的。
//
InitializeComponent();
base.OnInit(e);
}

/// <summary>
/// 设计器支持所需的方法 - 不要使用代码编辑器修改
/// 此方法的内容。
/// </summary>
private void InitializeComponent()
{
this.sqlConnection1 = new System.Data.SqlClient.SqlConnection();
this.sqlCommand1 = new System.Data.SqlClient.SqlCommand();
this.Button1.Click += new System.EventHandler(this.Button1_Click);
//
// sqlConnection1
//
this.sqlConnection1.ConnectionString = "workstation id=ANT;packet size=4096;integrated security=SSPI;data source=ANT;pers " +
"ist security info=False;initial catalog=anttest ";
//
// sqlCommand1
//
this.sqlCommand1.Connection = this.sqlConnection1;
this.Load += new System.EventHandler(this.Page_Load);

}
#endregion

private void Button1_Click(object sender, System.EventArgs e)
{}
public class SQLDR

{

static void Main(string[] args)

{

// Step 1: Make a connection.

SqlConnection sqlConnection1 = new sqlConnection();

SqlConnection1.ConnectionString = "Provider=SqlClient.1; " +

"Integrated Security=SSPI; " + "Persist Security Info=False; " +

"Initial Catalog=Cars; " + "Data Source=BIGMANU; ";

sqlConnection1.Open();

// Step 2: Create a SQL command.

string strSQL = "SELECT * FROM students WHERE sex= '女 ' ";

SqlCommand sqlCommand1 = new SqlCommand(strSQL, sqlConnection1);

// Step 3: Obtain a data reader ala ExecuteReader().



SqlDataReader myDataReader;

SqlDataReader = SqlCommand.ExecuteReader();

// Step 4: Loop over the results.
while (myDataReader.Read())
{

Console.WriteLine( "Red car: " +

myDataReader[ "strSQL "].ToString());

}

myDataReader.Close();

sqlConnection1.Close();

}

}



[解决办法]
Console.WriteLine( "Red car: " + myDataReader[ "strSQL "].ToString());
====================================================================
Response.Write( "Red car: " + myDataReader[ "strSQL "].ToString() + " <br /> ");

在网页里用控制台的Console.WriteLine,打算给谁看啊


[解决办法]
楼上那位大哥已经指出症结了,还有你的这些程序应该放在Page_load中?
[解决办法]
static void Main(string[] args)
==============================
居然还有这个..

private void Page_Load(object sender, EventArgs e)
{

}
