如何从一个选项卡切换到另一个选项卡Xamarin IOS

Question

我创建的UITabBarController类有5个 ViewControllers

        controller1 = new Controller1();
        controller2 = new Controller2();
        controller3 = new Controller3();
        controller4 = new Controller4();
        controller5 = new Controller5();

        controller1.TabBarItem = new UITabBarItem ("first", UIImage.FromFile("/Images/first.png"), 0);
        controller5.TabBarItem = new UITabBarItem ("second", UIImage.FromFile("/Images/four.png"), 1);
        controller5.TabBarItem = new UITabBarItem ("third", UIImage.FromFile("/Images/four.png"), 2);
        controller5.TabBarItem = new UITabBarItem ("four", UIImage.FromFile("/Images/four.png"), 3);
        controller5.TabBarItem = new UITabBarItem ("five", UIImage.FromFile("/Images/four.png"), 4);

    var tabs = new UIViewController[] {
            controller1, controller2, controller3, controller4, controller5 
        };
        ViewControllers = tabs;

在第三个控制器中,我有一个提交按钮.

在提交按钮的动作,我想从切换标签controller3到controller5.

我该怎么做呢？

像这样的东西:

this.TabBarController.SelectedIndex = 4;
