将对象添加到列表，不能指定给Add，因为它是一种分组方法

当前以下代码出现错误，我不知道如何修复！

这是错误：Cannot assign to 'Add' because it is a 'method group'

这是我的App.xaml.cs:

public partial class App : Application
{
    //Public list of users and form can access
    List<User> LoggedUsers = new List<User>();
    //First startup of the application
    public void Application_Startup(object sender, StartupEventArgs e)
    {
        //First startup, display the login form
        LoginWindow FirstLogin = new LoginWindow();
        FirstLogin.ShowDialog();
        //If the login form was closed properly, handle the user
        if (FirstLogin.DialogResult == true)
        {
            //Add the user to the list of logged users
            User returned = FirstLogin.returnUser;
            //Create temp duplicate for testing
            User tmp = new User();
            tmp.Email = "email@gmail.com";
            tmp.FirstName = "John";
            tmp.LastName = "Johnson";
            tmp.ID = "01";
            tmp.Permissions = 1;
            LoggedUsers.Add = tmp;
            LoggedUsers.Add = returned;
        }
    }
}

这是我的LoginDow.xaml.cs，用户对象在关闭时从中返回（返回）：

//Give App access to user object outside of this form
public User returnUser
{
    get
    {
        return user;
    }
}
//Public user object, start empty
User user = new User();
//Check the login
private void doLogin(string username, string password)
{
    //User logged in, add data to user object
    user.Email = "email@gmail.com";
    user.FirstName = "John";
    user.LastName = "Johnson";
    user.ID = "01";
    user.Permissions = 1;
    //Close the form with dialog result "true"
    this.DialogResult = true;
    this.Close();
}

还有课堂，如果你需要的话：

//Logged in users class
Public Class User
{
    public string ID { get; set; }
    public string FirstName { get; set; }
    public string LastName { get; set; }
    public string Email { get; set; }
    public Int16 Permissions { get; set; }
}

当我修复了这个问题时，为了一些测试目的，将一个重复的对象添加到列表中。

将对象添加到列表，不能指定给Add，因为它是一种分组方法

List.Add()是一个方法而不是属性：

LoggedUsers.Add(tmp);
LoggedUsers.Add(returned);
