C# .Net 发布后,把dll全部放在一个文件夹中,让软件目录更整洁

PublishFolderCleaner – Github

测试环境:

.Net 8

Program.cs 代码

// https://github.com/dotnet-campus/dotnetcampus.DotNETBuildSDK/tree/master/PublishFolderCleanerusing System.Diagnostics;
using System.Text;// 名称, 不用写 .exe
var exeName = "AbpDemo";
// 目录
var publishFolder = "D:\\Work\\CSharpProject\\AbpDemo\\AbpDemo\\bin\\Debug\\net8.0";const string libFolderName = "lib";
var libFolder = Path.GetFullPath(Path.Combine(publishFolder, libFolderName));

}string ChangeExecutableExtension(string apphostExe) =>// Windows apphosts have an .exe extension. Don't call Path.ChangeExtension() unless it's guaranteed// to have an .exe extension, eg. 'some.file' => 'some.file.dll', not 'some.dll'apphostExe.EndsWith(".exe", StringComparison.OrdinalIgnoreCase) ? Path.ChangeExtension(apphostExe, ".dll") : apphostExe + ".dll";int GetOffset(byte[] bytes, byte[] pattern)
{int si = 0;var b = pattern[0];while (si < bytes.Length){si = Array.IndexOf(bytes, b, si);if (si < 0)break;if (Match(bytes, si, pattern))return si;si++;}return -1;
}bool Match(byte[] bytes, int index, byte[] pattern)
{if (index + pattern.Length > bytes.Length)return false;for (int i = 0; i < pattern.Length; i++){if (bytes[index + i] != pattern[i])return false;}return true;
}

效果真不错
