Windows窗体应用程序的身份验证

No。会员系统是Asp.net的一部分，虽然你可以在winforms应用程序中使用它，但它不会很干净。

如果你已经在数据库中有了用户名和密码，那么你最好的选择是实现一个直接的身份验证系统，除非你担心人们对代码进行逆向工程…在这种情况下，防止逆向工程是一件更高级的事情。

编辑:

微软确实有Windows身份基础，但它确实是一个比你可能想要的更复杂的系统。

我通常创建一个像这样的新表单。

public partial class LoginForm : Form
{
    public bool letsGO = false;
    public LoginForm()
    {
        InitializeComponent();
        textUser.CharacterCasing = CharacterCasing.Upper;
    }
    public string UserName
    {
        get
        {
            return textUser.Text;
        }
    }
    private static DataTable LookupUser(string Username)
    {
        const string connStr = "Server=(local);" +
                            "Database=LabelPrinter;" +
                            "trusted_connection= true;" +
                            "integrated security= true;" +
                            "Connect Timeout=1000;";
        //"Data Source=apex2006sql;Initial Catalog=Leather;Integrated Security=True;";
        const string query = "Select password From dbo.UserTable (NOLOCK) Where UserName = @UserName";
        DataTable result = new DataTable();
        using (SqlConnection conn = new SqlConnection(connStr))
        {
            conn.Open();
            using (SqlCommand cmd = new SqlCommand(query, conn))
            {
                cmd.Parameters.Add("@UserName", SqlDbType.VarChar).Value = Username;
                using (SqlDataReader dr = cmd.ExecuteReader())
                {
                    result.Load(dr);
                }
            }
        }
        return result;
    }
    private void HoldButton()
    {
        if (string.IsNullOrEmpty(textUser.Text))
        {
            //Focus box before showing a message
            textUser.Focus();
            MessageBox.Show("Enter your username", this.Text, MessageBoxButtons.OK, MessageBoxIcon.Information);
            //Focus again afterwards, sometimes people double click message boxes and select another control accidentally
            textUser.Focus();
            textPass.Clear();
            return;
        }
        else if (string.IsNullOrEmpty(textPass.Text))
        {
            textPass.Focus();
            MessageBox.Show("Enter your password", this.Text, MessageBoxButtons.OK, MessageBoxIcon.Information);
            textPass.Focus();
            return;
        }
        //OK they enter a user and pass, lets see if they can authenticate
        using (DataTable dt = LookupUser(textUser.Text))
        {
            if (dt.Rows.Count == 0)
            {
                textUser.Focus();
                MessageBox.Show("Invalid username.", this.Text, MessageBoxButtons.OK, MessageBoxIcon.Error);
                textUser.Focus();
                textUser.Clear();
                textPass.Clear();
                return;
            }
            else
            {
                string dbPassword = Convert.ToString(dt.Rows[0]["Password"]);
                string appPassword = Convert.ToString(textPass.Text); //we store the password as encrypted in the DB
                Console.WriteLine(string.Compare(dbPassword, appPassword));
                if (string.Compare(dbPassword, appPassword) == 0)
                {
                    DialogResult = DialogResult.OK;
                    this.Close();
                }
                else
                {
                    //You may want to use the same error message so they can't tell which field they got wrong
                    textPass.Focus();
                    MessageBox.Show("Invalid Password", this.Text, MessageBoxButtons.OK, MessageBoxIcon.Information);
                    textPass.Focus();
                    textPass.Clear();
                    return;
                }
            }
        }
    }
    private void textPass_KeyDown_1(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Return)
        {
            HoldButton();
        }
    }
    private void buttonLogin_Click(object sender, EventArgs e)
    {
        HoldButton();
    }
    private void textPass_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Return)
        {
            HoldButton();
        }
    }
}

然后在主表单中这样做:

public Form1(string userName)
{
    //this is incase a user has a particular setting in your form
    //so pass name into contructer
}

最后:

static class Program
{
    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        LoginForm fLogin = new LoginForm();
        if (fLogin.ShowDialog() == DialogResult.OK)
        {
            Application.Run(new Form1(fLogin.UserName));
        }
        else
        {
            Application.Exit();
        }
        //Application.Run(new Form1());
    }

希望这给了一个关于做什么的一般想法，虽然我确信他们有更好的方法来做到这一点，也要注意这不是真正安全的前端。

希望有帮助:

编辑:哦，在我忘记之前不要使用

Select password From dbo.UserTable (NOLOCK) Where UserName = @UserName 

我就把它扔到存储过程中。但无论如何，这不是最好的认证方式，但它是一个有效的解决方案，至少让你开始，我希望
