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;

namespace Form1

public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();

}
SqlConnection conn = new SqlConnection();
conn.open();
SqlCommand co=new SqlCommand();
co.Connection=conn;
com="select timenian from jifeng ";
SqlDataReader data=conn.ExcuteReader();
if(data.Read())
{
textBox1.text=data["timenian"].Tostring;
}
co="select timeyue from jifeng";
SqlDataReader data =conn.ExcuteReader();
if (data.Read())
{
textBox2.text=data["timeyue"].Tostring;
data.Close();
conn.Close();
private void Form1_Load(object sender, EventArgs e)
{

}

private void button1_Click(object sender, EventArgs e)
{
Form2 fm = new Form2();
fm.Show();
}
}
}

Answer 1

把上面一段替换成

private void Form1_Load(object sender, EventArgs e)
        {
            SqlConnection conn = new SqlConnection();
            conn.Open();
            try
            {
                SqlCommand co = new SqlCommand();
                co.Connection = conn;
                co.CommandText = "select timenian,timeyue from jifeng ";
                SqlDataReader data = co.ExecuteReader();
                if (data.Read())
                {
                    textBox1.text=data["timenian"].Tostring;
                    textBox2.text=data["timeyue"].Tostring;
                }
                data.Close();
            }
            catch (Exception ex)
            {
                throw ex;
            }
            finally
            {
                conn.Close();
            }
        }

你上面有的是名字写错了，有的是地方放错了

把第13，14行的text 改为 Text ， ToString后面加个括号改为ToString()

Answer 2

SqlDataReader data 这个data是二维的 吧

Answer 3

Answer 4

如果有问题的话，vs显示的。

Answer 5

如果有问题，那就是语法问题
if (data.Read())
{
textBox2.text=data["timeyue"].Tostring;
｝//这里少了个大括号
