C#Unmanaged Export无效

我想让Unmanaged Export基本样本正常工作。

我正在遵循的步骤:

  • 创建一个新的classlibrary项目。
  • 添加UnmanagedExports 的NuGet。
  • 将CPU目标更改为x86。
  • 将我关注的教程中的代码添加到.cs文件中。
  • 构建

该项目非常成功,但当我用DLL Export Viewer检查我的dll时,我看不到任何功能。

我正在使用32位操作系统和SharpDevelop 4.4(我也尝试过其他SharpDevelop版本和64位操作系统,结果相同)。

我的sln档案:

Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "test", "test\test.csproj", "{AFAA816C-65B2-4B58-9FB2-EB7482AA0F5F}"
    EndProject
    Global
        GlobalSection(SolutionConfigurationPlatforms) = preSolution
            Debug|x86 = Debug|x86
            Release|x86 = Release|x86
        EndGlobalSection
        GlobalSection(ProjectConfigurationPlatforms) = postSolution
            {AFAA816C-65B2-4B58-9FB2-EB7482AA0F5F}.Debug|x86.ActiveCfg = Debug|x86
            {AFAA816C-65B2-4B58-9FB2-EB7482AA0F5F}.Debug|x86.Build.0 = Debug|x86
            {AFAA816C-65B2-4B58-9FB2-EB7482AA0F5F}.Release|x86.ActiveCfg = Release|x86
            {AFAA816C-65B2-4B58-9FB2-EB7482AA0F5F}.Release|x86.Build.0 = Release|x86
        EndGlobalSection
    EndGlobal

        }

我的dll的Dll导出查看器 DLL export viewer of my dll

工作dll的Dll导出查看器(从教程网站下载) Dll Export Viewer of a working dll (downloaded from the tutorial web)

两个dll(我和下载的)都具有相同的操作系统大小,但不适用于DLL导出查看器。

我缺少什么?

我遇到了同样的问题,我以这种方式解决了这个问题, 您需要在该行csproj文件下面添加以下行

  <Import Project="$(MSBuildToolsPath)\Microsoft.CSharp.targets" />

  <!-- Remove this comment and insert This line-->
  <Import Project="packages/UnmanagedExports.1.2.7/tools/RGiesecke.DllExport.targets" Condition="Exists('packages/UnmanagedExports.1.2.7/tools/RGiesecke.DllExport.targets')"/>

检查文件存在于您的文件夹“ packages / UnmanagedExports.1.2.7 / tools / RGiesecke.DllExport.targets”中
