Windows :: UI :: Xaml :: Horizo​​ntalAlignment与Windows :: UI :: Xaml :: FrameworkAlignment :: Horizo​​ntalAlignment [英] Windows::UI::Xaml::HorizontalAlignment versus Windows::UI::Xaml::FrameworkAlignment::HorizontalAlignment

问题描述

由于Horizo​​ntalAlignment实际上是我有一个using语句的Windows :: UI :: Xaml的成员，我很困惑为什么

  Horizo​​ntalAlignment :: Center产生以下编译器错误：

blankpage.xaml.cpp（43）：错误C2039：'中心'：不是'Windows :: UI :: Xaml :: FrameworkElement :: Horizo​​ntalAlignment'的成员

 
使用命名空间Windows :: UI :: Xaml; 
 
 
 void BlankPage :: OnNavigatedTo（NavigationEventArgs ^ e）
 {
 TextBlock ^ dynTextBlock = ref new TextBlock（）; 
 
 dynTextBlock-> Text =" dynTextBlock动态创建" ;; 
 dynTextBlock-> Horizo​​ntalAlignment = Windows :: UI :: Xaml :: Horizo​​ntalAlignment :: Center; 
 dynTextBlock-> Horizo​​ntalAlignment = Horizo​​ntalAlignment :: Center; 
 myGrid-> Children-> Append（dynTextBlock）; 
} 
 
   
 // Intellisense显示Windows :: UI :: Xaml :: Horizo​​ntalAlignment和Windows :: UI :: Xaml :: FrameworkAlignment :: Horizo​​ntalAlignment 
 
       
  
   < span style ="font-size：small"> // for dynTextBlock->水平对齐   
 
 
  

解决方案

 

Hello，

 

我认为编译器将Horizo​​ntalAlignment视为FrameworkElement。 Horizo​​ntalAlignment属性

http://msdn.microsoft.com/en-us/library/windows/apps/windows.ui.xaml.frameworkelement.horizo​​ntalalignment

 

所以你需要添加它的整个路径。

 

祝你好运，

杰西

Since HorizontalAlignment is in fact a member of Windows::UI::Xaml to which I have a using statement, I'm puzzled why

 HorizontalAlignment::Center produces the following compiler error:

blankpage.xaml.cpp(43): error C2039: 'Center' : is not a member of 'Windows::UI::Xaml::FrameworkElement::HorizontalAlignment'

using namespace Windows::UI::Xaml;


void BlankPage::OnNavigatedTo(NavigationEventArgs^ e)
{
	TextBlock^ dynTextBlock = ref new TextBlock(); 

	dynTextBlock->Text= "dynTextBlock created dynamically";
	dynTextBlock->HorizontalAlignment= Windows::UI::Xaml::HorizontalAlignment::Center;
  	dynTextBlock->HorizontalAlignment=                    HorizontalAlignment::Center;
	myGrid->Children->Append( dynTextBlock );
}
// Intellisense displays Windows::UI::Xaml::HorizontalAlignment  and   Windows::UI::Xaml::FrameworkAlignment::HorizontalAlignment
// for dynTextBlock->Horizontal alignment 

解决方案

 

Hello,

 

I think the complier treat HorizontalAlignment as the FrameworkElement.HorizontalAlignment property

http://msdn.microsoft.com/en-us/library/windows/apps/windows.ui.xaml.frameworkelement.horizontalalignment

 

So that you need to add the whole path of it.

 

Best regards,

Jesse
