如何在3次尝试中关闭登录表单

Question

如果用户未能登录3次，如何关闭登录表单。我应该怎么做才能实现它？

if (user == "Admin" && pass == "Admin")
{

    //if user and pass are correct
    MessageBox.Show("Admin Access", "Access Granted",
    MessageBoxButtons.OK, MessageBoxIcon.Information);

    //will transfer to the next form
    frmItems frmitem = new frmItems();
    frmitem.Show();
    this.Hide();
}
else
{
    //to make the textbox null if the pass is wrong
    txtUser.Text = "";
    txtPass.Text = "";
    count = 0;
    count++;

    //if the user or pass are wrong
    MessageBox.Show("Invalid User/Passwosrd", "Access Denied",
    MessageBoxButtons.OK, MessageBoxIcon.Error);

    /close the program if the pass/user failed 3 times
    if (count == 3)
    {
        MessageBox.Show("This program will close", "Access Denied",
        MessageBoxButtons.OK, MessageBoxIcon.Warning);
    }      
}

现在，您正在函数内部进行，因为每次将变量设置回0时。

您只需将count的值设置为0即可定义它。希望你把你的计数变量作为全局变量。
