windows - 创建一个应用程序并在右键单击文件时附加它

Question

我想最好在 C# VS12 中制作一个应用程序，并且我想将它附加在右键菜单上，将文件路径作为参数传递，如果我也可以在多项选择中做到这一点，那就太好了。我该如何做到这一点？

Answer 1

in the installer of your application you need to add a file extension association. (for development you can test that by registering the extension manually: right click, open with...). the file name that was clicked will be passed to your app as a command line argument (those are the args[] in the main method of you app).

multiple selection is a bit trickier but certainly doable. when your app starts you need to check if you have an instance of the app already running (using a mutex for example) and send a message to that instance with the file name you received.

If you have not worked with context menu handling, you should take a look at this tutorial.

For the file path handling, you could take a look at this image editing example.
