使用C＃引脚* .lnk文件到Windows 7任务栏 [英] Pin *.lnk file to Windows 7 Taskbar using C#

问题描述

在Windows 7图标即使是纲领性牵制似乎它是不允许的（如这里说的：的 http://msdn.microsoft.com/en-us/library/dd378460（v = VS.85）的.aspx ），也有做这个的一些方法使用一些VB脚本。
有人发现这样在C＃这样做的方式：

Even the programmatic pinning of icons in Windows 7 seems it's not permitted (like it says here: http://msdn.microsoft.com/en-us/library/dd378460(v=VS.85).aspx), there are some methods for doing this by using some VB scripts. Someone found a way of doing this in C# like this:

private static void PinUnpinTaskBar(string filePath, bool pin)
{
     if (!File.Exists(filePath)) throw new FileNotFoundException(filePath);

     // create the shell application object
     dynamic shellApplication = Activator.CreateInstance(Type.GetTypeFromProgID("Shell.Application"));

     string path = Path.GetDirectoryName(filePath);
     string fileName = Path.GetFileName(filePath);

     dynamic directory = shellApplication.NameSpace(path);
     dynamic link = directory.ParseName(fileName);

     dynamic verbs = link.Verbs();
     for (int i = 0; i < verbs.Count(); i++)
        {
            dynamic verb = verbs.Item(i);
            string verbName = verb.Name.Replace(@"&", string.Empty).ToLower();

            if ((pin && verbName.Equals("pin to taskbar")) || (!pin && verbName.Equals("unpin from taskbar")))
            {

                verb.DoIt();
            }
        }

        shellApplication = null;
}

如可以看到的，该代码使用的框架4.0的特性。我想问的问题是：这个功能被转换，因此它会做出同样的事情，但只用3.5框架？任何想法？

As can be seen, the code makes use of .NET Framework 4.0 features. The question I want to ask is: can this function be transformed so it would make the same thing, but using just 3.5 Framework? Any ideas?

推荐答案

简单...

    private static void PinUnpinTaskBar(string filePath, bool pin) {
        if (!File.Exists(filePath)) throw new FileNotFoundException(filePath);

        // create the shell application object
        Shell shellApplication = new ShellClass();

        string path = Path.GetDirectoryName(filePath);
        string fileName = Path.GetFileName(filePath);

        Folder directory = shellApplication.NameSpace(path);
        FolderItem link = directory.ParseName(fileName);

        FolderItemVerbs verbs = link.Verbs();
        for (int i = 0; i < verbs.Count; i++) {
            FolderItemVerb verb = verbs.Item(i);
            string verbName = verb.Name.Replace(@"&", string.Empty).ToLower();

            if ((pin && verbName.Equals("pin to taskbar")) || (!pin && verbName.Equals("unpin from taskbar"))) {

                verb.DoIt();
            }
        }

        shellApplication = null;
    }

一定要添加一个COM提到微软壳牌控制和自动化。

Be sure to add a COM reference to "Microsoft Shell Controls And Automation".

如果您希望继续使用Activator.CreateInstance的现有方法，所以你不必有多余的COM互操作DLL，那么你将不得不使用反射。但是，这将使得代码有很多丑陋。

If you want to keep the existing method of using Activator.CreateInstance so you don't have to have the extra COM interop DLL then you'll have to use reflection. But that would make the code a lot uglier.
