怎么才能把sqlcommand中的sql语句查询出来的结果放到textbox中去 比如这样个例子
using System;
using System.Collections.Generic;
using System.Text;
using System.Data.SqlClient;

namespace 查询
{
    class Program
    {
        static void Main(string[] args)
        {
            SqlConnection connection = new SqlConnection();
            connection.ConnectionString = "Data Source=WWW-2568B4977E8\\FREENESS;Initial Catalog=Exercise;Integrated Security=true";
            connection.Open();
            SqlCommand cmd = new SqlCommand("select * from Friend", connection);
            SqlDataReader myReader = cmd.ExecuteReader();
            到这边都没问题 接下来是怎么把sqlcommand中查的数据放到textbox中啊
        }
    }
}

晕 发错了 上面那个是控制台的程序 应该是这个
using System;
using System.Collections.Generic;
using
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using System.Data.SqlClient;

namespace WindowsApplication2
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {
            SqlConnection connection = new SqlConnection();
            connection.ConnectionString = "Data Source=WWW-2568B4977E8\\FREENESS;Initial Catalog=Exercise;Integrated Security=true";
            connection.Open();
            SqlCommand cmd = new SqlCommand("select * from Friend", connection);
            SqlDataReader myReader = cmd.ExecuteReader();
            //这边textbox应该怎么写？
        }
    }
}
