查看留⾔界⾯：
protected void Page_Load(object sender, EventArgs e)
{
string conn = "Data Source=.;Initial Catalog=Information;Integrated Security=True";
SqlConnection con = new SqlConnection(conn);
string sqlstr = "select*from Message";
SqlDataAdapter ad = new SqlDataAdapter(sqlstr,con);
DataSet ds = new DataSet();
con.Open();
ad.Fill(ds);
con.Close();
DataList1.DataSource = ds.Tables[0].DefaultView;
DataList1.DataBind();
}
留⾔界⾯：
using System.Data.SqlClient;
using System.Data;
protected void Button2_Click(object sender, EventArgs e)//取消留⾔
{
TextBox1.Text = "";
TextBox2.Text = "";
TextBox3.Text = "";
}
protected void Button1_Click(object sender, EventArgs e)//发送留⾔
{
string conn = "Data Source=.;Initial Catalog=Information;Integrated Security=True";
SqlConnection con = new SqlConnection(conn);
string sqlstr = "insert into Message(username,sex,email,contente,p_w_picpathadd)values('" + TextBox1.Text + "','" + RadioButtonList1.SelectedValue + "','" + TextBox2.Text + "','" + TextBox3.Text + "','3.jpg')";
SqlDataAdapter ad = new SqlDataAdapter(sqlstr, con);
DataSet ds = new DataSet();
ad.Fill(ds);
