I think you will need to use COM and add a reference to "Microsoft Shell Control And Automation", as described in this blog post:
我认为您需要使用 COM 并添加对“Microsoft Shell 控制和自动化”的引用，如本博客文章所述：
Here's an example using the code provided there:
这是使用那里提供的代码的示例：
namespace Shortcut
{
using System;
using System.Diagnostics;
using System.IO;
using Shell32;
class Program
{
public static string GetShortcutTargetFile(string shortcutFilename)
{
string pathOnly = System.IO.Path.GetDirectoryName(shortcutFilename);
string filenameOnly = System.IO.Path.GetFileName(shortcutFilename);
Shell shell = new Shell();
Folder folder = shell.NameSpace(pathOnly);
FolderItem folderItem = folder.ParseName(filenameOnly);
if (folderItem != null)
{
Shell32.ShellLinkObject link = (Shell32.ShellLinkObject)folderItem.GetLink;
return link.Path;
}
return string.Empty;
}
static void Main(string[] args)
{
const string path = @"C:\link to foobar.lnk";
Console.WriteLine(GetShortcutTargetFile(path));
}
}
}

All file shortcuts have a .lnk file extension you can check for. Using a string for example, you could use string.EndsWith(".lnk") as a filter.
所有文件快捷方式都有一个 .lnk 文件扩展名，您可以检查。例如，使用字符串，您可以使用 string.EndsWith(".lnk") 作为过滤器。
All URL shortcuts have a .url file extension, so you will need to account for those as well if needed.
所有 URL 快捷方式都有一个 .url 文件扩展名，因此如果需要，您还需要考虑这些。

If you don't want to use dependencies you can use https://blez.wordpress.com/2013/02/18/get-file-shortcuts-target-with-c/But lnk format is undocumented, so do it only if you understand risks.
如果您不想使用依赖项，您可以使用https://blez.wordpress.com/2013/02/18/get-file-shortcuts-target-with-c/但是 lnk 格式没有记录，所以只做如果您了解风险。

if you want find your application path that has shortcut on desktop, an easy way that i use, is the following:
如果您想在桌面上找到具有快捷方式的应用程序路径，我使用的一种简单方法如下：
Process.GetCurrentProcess().MainModule.FileName.Substring(0, Process.GetCurrentProcess().MainModule.FileName.LastIndexOf("\")
this code return any exe path that is running,Regardless that who requested file
此代码返回任何正在运行的 exe 路径，无论谁请求文件

An even simpler way to get the linked path that I use is:
获取我使用的链接路径的更简单方法是：
private static string LnkToFile(string fileLink)
{
string link = File.ReadAllText(fileLink);
int i1 = link.IndexOf("DATA// new way for windows 10
string targetname;
string pathOnly = System.IO.Path.GetDirectoryName(LnkFileName);
string filenameOnly = System.IO.Path.GetFileName(LnkFileName);
Shell shell = new Shell();
Shell32.Folder folder = shell.NameSpace(pathOnly);
FolderItem folderItem = folder.ParseName(filenameOnly);
if (folderItem != null) {
Shell32.ShellLinkObject link = (Shell32.ShellLinkObject)folderItem.GetLink;
targetname = link.Target.Path; // <-- main difference
if (targetname.StartsWith("{")) { // it is prefixed with {54A35DE2-guid-for-program-files-x86-QZ32BP4}
int endguid = targetname.IndexOf("}");
if (endguid > 0) {
targetname = "C:\program files (x86)" + targetname.Substring(endguid + 1);
}
}
");
if (i1 < 0)
return null;
i1 += 5;
int i2 = link.IndexOf("var fileName = Process.GetCurrentProcess().MainModule.FileName;
var folderName = Path.Combine(fileName, ".."); //origin folder
", i1);
if (i2 < 0)
return link.Substring(i1);
else
return link.Substring(i1, i2 - i1);
}
But it will of course break if the lnk-file format changes.
但如果 lnk 文件格式发生变化，它当然会中断。

In windows 10 it needs to be done like this, first add COM reference to "Microsoft Shell Control And Automation"
在windows 10中需要这样做，首先将COM引用添加到“Microsoft Shell Control And Automation”
