此处是一段代码，可让您创建文件夹快捷方式. (通常)可以通过声明一个用装饰的简单类来替换CoCreateInstance.具有所需CLSID的Guid 属性和 ComImport 属性. new调用将自动执行COM魔术.使用此代码，您甚至不需要Shell32引用(或者您可以根据需要从那里重用IShellLink声明).

Here is a piece of code that allows you to create a folder shortcut. The CoCreateInstance can (in general) be replaced by declaring a simple class decorated with the Guid attribute with the required CLSID, and the ComImport attribute. The new call will do the COM magic automatically. With this code, you don't even need a Shell32 reference (or you can reuse the IShellLink declaration from there if you prefer).

用法:

static void Main(string[] args)
{
    CreateFolderShortcut(@"c:\temp", Path.GetFullPath("Shortcut to Temp"));
}

代码:

public static void CreateFolderShortcut(string path, string shortcutPath)
{
    CreateFolderShortcut(path, shortcutPath, null);
}

public static void CreateFolderShortcut(string path, string shortcutPath, string comment)
{
    if (path == null)
        throw new ArgumentNullException("path");

    IShellLink link = (IShellLink)new ShellLinkFolder();

    if (comment != null)
    {
        link.SetDescription(comment);
    }
    link.SetPath(path);

    IPersistFile file = (IPersistFile)link;
    file.Save(shortcutPath, false);
}
