使用Visual Studio运行Fortran DLL

问题描述：

我使用Visual Studio 2010开发了一个网站。我想运行一个Fortran DLL。我使用英特尔Visual Fortran创建一个.dll并测试如何使用它。我的代码是：

I develop a website with Visual Studio 2010. I want to run a Fortran DLL. I used Intel Visual Fortran to create a .dll and to test how to use it. My code is:

      SUBROUTINE SIMPSON (N,H,I)

     !DEC$ ATTRIBUTES DLLEXPORT, DECORATE, ALIAS : "SIMPSON" :: SIMPSON
     !DEC$ ATTRIBUTES REFERENCE::N
     !DEC$ ATTRIBUTES REFERENCE::H
     !DEC$ ATTRIBUTES REFERENCE::I
      INTEGER N,H,I

      I=N+H

      RETURN
      END

其实际上需要两个整数，添加它们并返回结果。现在我有.dll我不知道如何使用Visual Studio运行它。任何知道的人都可以告诉我要遵循的步骤吗？

which practically takes two integers, adds them and return the result. Now I have the .dll I don't know how to run it with Visual Studio. Can anyone who knows please give me steps to follow?

答

我一直都这样做。我在做什么，在调用项目（ C＃， VB.NET ）我添加 .dll 作为现有项目输出到项目，其中添加为链接选项。然后我将其设置为复制，如果在项目树中是较新的。

I do this all the time. What I do, is in the calling project (C#, VB.NET) I add the .dll output to the project as an existing item, with Add as Link option. Then I set it to copy if newer in the project tree.

最后，当您将其编译到 bin / Debug 或 bin / Release 文件夹。

In the end it follows the binary when you compile it into the bin/Debug or bin/Release folders.

使用 C＃然后使用 [DllImport ）] attrbiute这样：

With C# you then use the [DllImport()] attrbiute like this:

[DllImport("trex_pc.dll")]
static extern Simpson(ref int N, ref int H, ref int I);
