Windows運行時組件是Windows 8裏面通用的公共庫,它可以使用C++,C#或者VB來編寫,不過你的Windows 8 metro是用什麼語言編寫都可以調用無縫地調用Windows運行時組件。
下面通過一個C#編寫的Windows 8項目來調用一個用C++編寫的Windows運行時組件。
創建一個Windows運行時組件:
編寫如下的代碼:
- #include "pch.h"
- #include "WinRTComponent.h"
- using namespace CppWinRTComponentDll2;
- int CalculatorSample::Add(int x, int y)
- {
- return x+y;
- }
頭文件
- #pragma once
- using namespace Windows::Foundation;
- namespace CppWinRTComponentDll2
- {
- public ref class CalculatorSample sealed
- {
- public:
- int Add(int x, int y);
- };
- }
在C#編寫的項目中調用Windows運行時組件的C++方法

- private void Button_Click_1(object sender, RoutedEventArgs e)
- {
- if (txtX.Text != "" && txtY.Text != "")
- {
- CalculatorSample calcobj = new CalculatorSample();//直接創建Windows運行時裏面的對象,很方便
- int x = Convert.ToInt32(txtX.Text.ToString());
- int y = Convert.ToInt32(txtY.Text.ToString());
- txtAddResult.Text = calcobj.Add(x,y).ToString();//調用Windows運行時裏面的方法
- }
- }
- }
- }
