跟着视频来的，不知道代码哪里出错了，求解。

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Data.SqlClient;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

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

        private void button1_Click(object sender, EventArgs e)
        {
            string id = textBox1.Text;
            string pwd = textBox2.Text;

            SqlConnection conn = new SqlConnection();
            conn.ConnectionString = "Server=.;uid=sa;pwd=112233;database=T_uird";
            conn.Open();
            SqlCommand cmd =new SqlCommand("server *from name='"+id+"'"+"and password='"+pwd+"'",conn);

            SqlDataReader sdr = cmd.ExecuteReader();

            if (sdr.HasRows)
            {
                MessageBox.Show("登录成功！");
                Form2 f2 = new Form2();
                f2.ShowDialog();
            }

            else
            {
                MessageBox.Show("账号或密码输入错误，请重新输入！");
            }
            sdr.Close();
            conn.Close();
        }
    }
}

Answer 1

"server *from name='"+id+"'"+"and password='"+pwd+"'"
你的表的呢？
而且是select，不是server，where也不见了

SqlCommand cmd =new SqlCommand("select * from 表名 where name='"+id+"' and password='"+pwd+"'",conn);
