Windows运行时组件是Windows 8里面通用的公共库,它可以使用C++,C#或者VB来编写,不过你的Windows 8 metro是用什么语言编写都可以调用无缝地调用Windows运行时组件。
下面通过一个C#编写的Windows 8项目来调用一个用C++编写的Windows运行时组件。
创建一个Windows运行时组件:
编写如下的代码:
#include "pch.h"
#include "WinRTComponent.h"
using namespace CppWinRTComponentDll2;
int CalculatorSample::Add(int x, int y)
{
return x+y;
}
头文件
#pragma once
using namespace Windows::Foundation;
namespace CppWinRTComponentDll2
public ref class CalculatorSample sealed
{
public:
int Add(int x, int y);
};
在C#编写的项目中调用Windows运行时组件的C++方法

<TextBlock Text="+" HorizontalAlignment="Center" Height="45" Width="258" FontSize="14" FontWeight="Bold"/>
<TextBox x:Name="txtY" HorizontalAlignment="Center" Height="45" Width="258"></TextBox>
<Button Content="调用WinRT方法来相加" HorizontalAlignment="Center" Click="Button_Click_1" ></Button>
<TextBox x:Name="txtAddResult" HorizontalAlignment="Center" Height="45" Width="258"/>
</StackPanel>
</Grid>
</Page>
C#代码部分

using Windows.UI.Xaml.Input;
using Windows.UI.Xaml.Media;
using Windows.UI.Xaml.Navigation;
using CppWinRTComponentDll2;//引入Windows运行时的空间
namespace TestWinRTCSDemo
public sealed partial class MainPage : Page
public MainPage()
{
this.InitializeComponent();
}
protected override void OnNavigatedTo(NavigationEventArgs e)
private void Button_Click_1(object sender, RoutedEventArgs e)
if (txtX.Text != "" && txtY.Text != "")
{
CalculatorSample calcobj = new CalculatorSample();//直接创建Windows运行时里面的对象,很方便
int x = Convert.ToInt32(txtX.Text.ToString());
int y = Convert.ToInt32(txtY.Text.ToString());
txtAddResult.Text = calcobj.Add(x,y).ToString();//调用Windows运行时里面的方法
}
}
运行的效果
