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

UI部分
- <Page
- x:Class="TestWinRTCSDemo.MainPage"
- IsTabStop="false"
- xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
- xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
- xmlns:local="using:TestWinRTCSDemo"
- xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
- xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
- mc:Ignorable="d">
- <Grid Background="{StaticResource ApplicationPageBackgroundThemeBrush}">
- <StackPanel>
- <TextBox x:Name="txtX" HorizontalAlignment="Center" Height="45" Width="258"></TextBox>
- <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 System;
- using System.Collections.Generic;
- using System.IO;
- using System.Linq;
- using Windows.Foundation;
- using Windows.Foundation.Collections;
- using Windows.UI.Xaml;
- using Windows.UI.Xaml.Controls;
- using Windows.UI.Xaml.Controls.Primitives;
- using Windows.UI.Xaml.Data;
- 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
