C ++/CLI中的DLL [英] DLL in C++/CLI

问题描述

您好，我想，如果有人可以在C ++/CLI中发布一个DLL的简单示例，以及如何在C ++/CLI中使用它.
不必太复杂，是的，很简单，例如我在控制台中键入一个值，该值将移至dll，并返回一个加，乘或除的值...

如果有人可以帮助我，我将不胜感激:)

Hello, I would like, if someone can post a simple example of a DLL in C++/CLI, and how to use it, also in C++/CLI.
Need not be complex, and yes, something simple, like I type a value in the console, this value goes to the dll, and returns a value added, or multiplied, or divided...

I am grateful if someone can help me:)

推荐答案

从以下内容开始:

Start with this : http://msdn.microsoft.com/en-us/library/a90k134d(VS.80).aspx[^]

Step 1:
create a project in Visual Studio that is a DLL project (C++)

Step 2:
add this code to the default code file it adds:

__declspec(dllexport) int doSomething(int value)
{
   return value * 5;
}

步骤3:
在Visual Studio中添加另一个项目，该项目是控制台应用程序(c ++)

步骤4:
将项目引用添加到在步骤1中创建的项目.

步骤5:
将此代码添加到从步骤3添加的默认代码文件中(在"main"功能之上)

Step 3:
add another project in Visual Studio that is a Console App (c++)

Step 4:
add a project reference to the project created in Step 1.

Step 5:
add this code to the default code file that is added from Step 3: (above the "main" function)

__declspec(dllimport) int doSomething(int value);

步骤6:
将此代码添加到应该在步骤3的默认代码文件中生成的"main"函数中.

Step 6:
add this code in the "main" function which should have been generated in the default code file from step 3:

doSomething(11);

步骤7:

在上述行上设置断点

步骤8:

按F5键.

步骤9:

进入代码..

Step 7:

set a breakpoint on the above line

Step 8:

hit the F5 key.

Step 9:

Step into the code..
