获取自带EXE的路径？

Question

If we're deploying a single file application , is there a way to get the single file application .exe 's path from inside our code?

The reason I'm asking is because I have a sample console application, which I'd like to register in the registry to start every time windows starts, but sadly every known API like Assembly.GetExecutingAssembly().Location , or the one suggested by Microsoft AppContext.BaseDirectory return paths relative to the actual .dll file of the console application, not the self-contained .exe which unpackages it all.

From GitHub issue , suggestion by @Symbai:

public static class Extensions {
    [System.Runtime.InteropServices.DllImport("kernel32.dll")]
    static extern uint GetModuleFileName(IntPtr hModule, System.Text.StringBuilder lpFilename, int nSize);
    static readonly int MAX_PATH = 255;
    public static string GetExecutablePath() {
        if (System.Runtime.InteropServices.RuntimeInformation.IsOSPlatform(System.Runtime.InteropServices.OSPlatform.Windows)) {
            var sb = new System.Text.StringBuilder(MAX_PATH);
            GetModuleFileName(IntPtr.Zero, sb, MAX_PATH);
            return sb.ToString();
        }
        else {
            return System.Diagnostics.Process.GetCurrentProcess().MainModule.FileName;
        }
    }
}
