如何通过代码实现datagridview中显示sqlsever的表

jhr123321 2014-10-22 04:34:37

代码如下：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Data.SqlClient;
using System.Collections;

namespace WindowsFormsApplication3
{
public partial class Form1 : Form
{
public SqlConnection m_con = new SqlConnection();
private DataGridView dataGridView = new DataGridView();
private BindingSource bindingSource1 = new BindingSource();
public Form1()
{
InitializeComponent();
}
DataSet wsgdwj = new DataSet();
SqlDataAdapter wsgdwj_path;

private void dataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e)
{

}

private void Form1_Load(object sender, EventArgs e)
{
string connsql = String.Format("server=127.0.0.1;Uid=sa;pwd=sasys;database=dnbs;");
//mySqlConnection1 = new MySqlConnection(connStr);
m_con.ConnectionString = connsql;
m_con.Open();

String str = "SELECT * FROM wsgdwj";
SqlDataAdapter da = new SqlDataAdapter(str, m_con);
DataSet ds = new DataSet();
da.Fill(ds, "wsgdwj");
//DataGridView dataGridView1 = new DataGridView();
//dataGridView1.DateSource = da;
//dataGridView1.DateBind();
dataGridView1.DataSource = ds.Table["wsgdwj"];
dataGridView1.DataBind();
m_con.Close();
}
}
}
程序报错：
错误 1 “System.Data.DataSet”不包含“Table”的定义，并且找不到可接受类型为“System.Data.DataSet”的第一个参数的扩展方法“Table”(是否缺少 using 指令或程序集引用?)
错误 2 “System.Windows.Forms.DataGridView”不包含“DataBind”的定义，并且找不到可接受类型为“System.Windows.Forms.DataGridView”的第一个参数的扩展方法“DataBind”(是否缺少 using 指令或程序集引用?)
求大神指点啊！小弟先在这谢过了！
