如何修复使用Delphi / C＃这样的非托管的出口困境 [英] How to fix this unmanaged exports trouble using Delphi/C#

问题描述

我碰到托管输出技术在此的 anwser 上左右。

I came across Unmanaged exports technique in this anwser on SO.

• 我可以管理自己有简单的项目工作 SharpDevelop的的，虽然我不知道有C＃的一个很好的命令。
• 我想用优秀的 Gavaghan.Geodesy （.NET / C＃）库写麦克Gavaghan。
• 我想避免的互操作性，通过COM。
• 我肯定用Delphi。我只是想利用图书馆吧。

• I can manage myself to have simplest project working on SharpDevelop, albeit I don't have a good command of C#.
• I want to use the excellent Gavaghan.Geodesy (.Net/C#) library written by Mike Gavaghan.
• I want to avoid interoperability through COM.
• I definitely use Delphi. I only want to harness the library with it.

我设法建立以下code：

I managed to build the following code :

using System;
using System.Collections.Generic;
using System.Text;
using RGiesecke.DllExport;

namespace DelphiNET
{
    internal static class UnmanagedExports
{
    [DllExport("add", CallingConvention = System.Runtime.InteropServices.CallingConvention.StdCall)]
    public static int add(int left, int right) {
        return left + right;            
        }

    }
}

我探讨其与德尔福，但是是徒劳的。

I probed it with Delphi but was in vain.

我检查了输出的dll用PE编辑器，但它原来没有出口数据都没有。

I checked the output dll with a PE editor but It turned out to have no export data at all.

我想念的东西，我很困惑。

I miss something and I'm confused.

推荐答案

我设法得到这个工作是这样的：

I managed to get this to work like this:

1. 下载C＃项目<一href="https://sites.google.com/site/robertgiesecke/Home/uploads/csharpprojecttemplateforunmanagedexports"相对=nofollow>模板。这需要Visual Studio，但你应该罚款以EX preSS版本。
2. 创建一个新的项目基于模板。
3. 在构建一个项目。
4. 在加载DLL的Dependency Walker中看到，它确实导出功能。我成功地调用德尔福的功能。

1. Download the C# Project template. This requires Visual Studio but you should be fine with the Express version.
2. Create a new project based on the template.
3. Build that project.
4. Load the DLL in Dependency Walker to see that it does indeed export the function. I succeeded in calling the function from Delphi.

请注意，为了查找DLL路径是斌\调试\ 86 。有一个在 A DLL斌\调试但这并没有出口。也许，这就是你一直在寻找。

Note that the path to find the DLL is bin\Debug\x86. There is a DLL in bin\Debug but this has no exports. Perhaps that's what you have been looking at.
