ty for your helps

What I have tried:

private void button1_Click(object sender, EventArgs e)
       {
           Form2 frm = new Form2();
           string username = "Vector";
           int number = 89-2;
           string password = "Vector" + number.ToString();
           if ((txtusername.Text == username) && (txtpassword.Text == password))
               this.Hide();
               frm.Show();
               MessageBox.Show("Welcome MR.Vector");
           else
               MessageBox.Show("Do not try to open this program");
           this.Close();
       }

推荐答案

您没有使用大括号在if / else语句中对多行代码进行分组。只有VB允许这样做。



C＃'101' - 它应该是：

You are not using braces to group multiple lines of code in the if / else statement. Only VB allows this.

C# '101' - It should be:

if ((txtusername.Text == username) && (txtpassword.Text == password))
{
    this.Hide();
    frm.Show();
    MessageBox.Show("Welcome MR.Vector");
}
else
{
    MessageBox.Show("Do not try to open this program");
}
