推荐答案

私有无效button1_Click(对象发送者，EventArgs e)
{


cn.Open();
cmd = new SqlCommand("select * from admin"，cn);
cmd.Connection = cn;
dr = cmd.ExecuteReader();
while(dr.Read())
{
if((textBox1.Text == dr [1] .ToString())&&(textBox2.Text == dr [2] .ToString()))
{
progressBar1.Visible = true;
progressBar1.Minimum = 1;
progressBar1.Maximum = 10000;
progressBar1.Value = 1;
progressBar1.Step = 1;
为(int i = 1; i< 10000; i ++)
progressBar1.PerformStep();
this.Hide();
Form2 sForm =新的Form2(textBox1.Text);
sForm.Show();
}
其他
{
MessageBox.Show(输入的数据无效！");
}
}

cn.Close();


}

private void button1_Click(object sender, EventArgs e)
{


cn.Open();
cmd = new SqlCommand("select * from admin", cn);
cmd.Connection = cn;
dr = cmd.ExecuteReader();
while (dr.Read())
{
if ((textBox1.Text == dr[1].ToString()) && (textBox2.Text == dr[2].ToString()))
{
progressBar1.Visible = true;
progressBar1.Minimum = 1;
progressBar1.Maximum = 10000;
progressBar1.Value = 1;
progressBar1.Step = 1;
for (int i = 1; i < 10000; i++)
progressBar1.PerformStep();
this.Hide();
Form2 sForm = new Form2(textBox1.Text);
sForm.Show();
}
else
{
MessageBox.Show("entered data''s not valid!!!");
}
}

cn.Close();


}
