C#中获取进程当前路径各种方法的测试

在CSharp中，获取当前进程的路径有很多种方式。同一个api在不同的运行和发布方式中，又会产生不同的效果。

下面我用代码来测试一下效果，运行环境是：Windows 10，.Net 8。
测试程序为放在``D:\的CurrentPathTest`目录。

//不同的发布及运行方式
//1. 发布为生成跨平台二进制文件，使用`dotnet CurrentPathTest.dll`启动程序
//2. 发布为独立应用，直接执行exe文件启动程序
//3. 发布为独立应用，安装到windows服务启动
//4. 发布为单文件独立应用`dotnet publish -c Release -r win-x64 /p:PublishSingleFile=true`
//5. 发布为单文件自解压独立应用`dotnet publish -c Release -r win-x64 /p:PublishSingleFile=true /p:IncludeAllContentForSelfExtract=true`
