Question

我试图使按钮可见，然后单击按钮使按钮不可见，但是我是Windows编码的新手，所以任何帮助都将对您有所帮助。

#include "pch.h"
#include "MainPage.xaml.h"
#include <iostream>

using namespace App1;

using namespace Platform;
using namespace Windows::Foundation;
using namespace Windows::Foundation::Collections;
using namespace Windows::UI::Xaml;
using namespace Windows::UI::Xaml::Controls;
using namespace Windows::UI::Xaml::Controls::Primitives;
using namespace Windows::UI::Xaml::Data;
using namespace Windows::UI::Xaml::Input;
using namespace Windows::UI::Xaml::Media;
using namespace Windows::UI::Xaml::Navigation;


// The Blank Page item template is documented at 
https://go.microsoft.com/fwlink/?LinkId=402352&clcid=0x409
int blockbase = 1 ;
MainPage::MainPage()
{
    InitializeComponent();
}
void App1::MainPage::Button_Click(Platform::Object^ sender, 
Windows::UI::Xaml::RoutedEventArgs^ e)
{
    greetingOutput->Text = "Hello, " + nameInput->Text + "! \n Welcome to the 
    worlds worst quiz show!!! \n Here is the one and only question: What 
    director directed the classic film Battleship Potempkin?";

    AnswerChoiceA-> Visibility = "Visible" ;
}

当前我遇到错误C2664和E1767 C2664：'无效的Windows :: UI :: Xaml :: UIElement :: Visibility :: set（Windows :: UI :: Xaml :: Visibility）'：无法将参数1从'const char [8]'转换为'Windows：：UI :: Xaml ::可见性'

E1767：函数“ Windows :: UI :: Xaml :: UIElement :: Visibility :: set”无法用给定的参数列表调用

如何使用C ++在Visual Studio 2017中更改可见性设置
