Answer 1

protected void Button1_Click(object sender, EventArgs e)
{
if (TextBox1.Text == "" || TextBox2.Text == "")
{
Response.Write("<script>alert('用户名或密码不能为空！')</script>"); //提示对话框
}
else
{
string ConStr = "server=(local);user id=sa;pwd=123456;database=userdb";
SqlConnection con = new SqlConnection(ConStr);
string SqlStr = "select * from mymember where sname = '" + TextBox1.Text + "' and spwd = '" + TextBox2.Text + "'"; //Select查询语句
SqlDataAdapter ada = new SqlDataAdapter(SqlStr, con);
con.Open(); //打开连接
DataSet ds = new DataSet();
ada.Fill(ds);
if (ds.Tables[0].Rows.Count > 0)
{
Session["username"] = TextBox1.Text;
Response.Redirect("index.aspx");
}
else
{
Response.Write("<script>alert('用户名或密码错误，请重新登录！')</script>");
}
} //绑定GridView控件

}
