Question

我有一个带登录界面的程序。用户可以通过选择单选按钮选择通过Windows身份验证模式或SQL服务器身份验证模式登录。以下是界面的快照：

当用户选择Windows身份验证时，用户无需在用户名和密码文本框中输入任何凭据。如果用户选择SQL server auth，则用户必须填写文本框上的凭据。因此，我想将windows auth的文本框设置为空白或不可见，这样如果用户尝试使用，则不允许用户输入凭据。

以下是代码：

private void btn_Login_Click(object sender, EventArgs e)
        {
            bool useWindowsAuth = WindowsAuth.Checked; // Check radio button for windows authentication

            string userName = string.Empty;
            string password = string.Empty;

            // Windows authentication mode : if textbox are empty , display message
            if (!useWindowsAuth)
            {
                userName = textBox1.Text;
                password = textBox2.Text;

                if (string.IsNullOrWhiteSpace(userName) || string.IsNullOrWhiteSpace(password))
                {
                    MessageBox.Show("Please provide Username and Password");
                    return;
                }
            }

            //create sql connection to both authentication mode
            var connStrBldr = new System.Data.SqlClient.SqlConnectionStringBuilder();
            connStrBldr.DataSource = "XXXXXXXXXX";
            connStrBldr.InitialCatalog = "Test";

            if (useWindowsAuth)
            {
                connStrBldr.IntegratedSecurity = true;  // accepts user login without any credentials
            }
            else
            {
                connStrBldr.IntegratedSecurity = false;  // accepts user login with credential stored in sql server
                connStrBldr.UserID = userName;
                connStrBldr.Password = password;
            }

            bool validUser = true;

            try
            {
                using (SqlConnection con = new SqlConnection(connStrBldr.ToString()))
                {
                    con.Open();
                    //lookup on login credentials in sql server
                }
            }
            catch (SqlException) // An exception will be caught if invalid credentials were used.
            {
                validUser = false;
            }

            //validate if user is successful or failed
            if (validUser)
            {
                MessageBox.Show("Login successful!");
                this.Hide();
                MainPage main = new MainPage();
                main.Show();
            }

            else
            {
                MessageBox.Show("Login failed!");
            }
        }

我需要什么属性来实现它？

这就是你要找的东西吗？

 textBox1.Enabled = false;

c＃ - 将登录文本框属性设置为不可见
