通过双击文件启动我的程序时，如何获取文件名？ [英] When my program is launched by double clicking on a file how can I get the file name?

问题描述

我已经将我的vb.net程序与文件扩展名相关联，这样如果我的程序使用的其中一个文件被双击，它将打开该程序。



我需要知道被点击的文件的名称。



我确信有一种非常简单的方法可以做到这一点，我只是不知道它是什么。如果有人能告诉我，我将不胜感激。



谢谢

Hi,
I've associated my vb.net program with a file extension so that if one of the files my program uses is double clicked it will open the program.

I need to know the name of the file that was clicked.

I'm sure there's a really easy way to do this, I just don't know what it is. I would appreciate it if someone could tell me.

Thanks

推荐答案

有一大堆 My.Application 和 My.Application.Info 下的内容。你应该能够在那里找到它，但是在我的脑海中，我不记得究竟在哪里。

There is a whole bunch of stuff under My.Application and My.Application.Info. You should be able to find it there, but off the top of my head, I cannot remember exactly where.

Homero Rivera使用了一个C＃示例，但原则仍然存在......你可以使用参数（参数）声明您的Main函数，例如

Homero Rivera used a C# example but the principle still stands...You can declare your Main function with arguments (parameters) e.g.

Module Module1
    Sub Main(ByVal CmdArgs() As String)
        For Each s As String In CmdArgs
            Console.WriteLine(s)
        Next
        Console.ReadKey()
    End Sub
End Module

如果你声明没有参数的Main函数，你仍然可以按照Peter_in_2780提供的链接访问命令行参数，例如

If you declare the Main function without arguments then you can still access the command line arguments as per the link provided by Peter_in_2780 e.g.

Module Module1
    Sub Main()
        For Each t As String In My.Application.CommandLineArgs
            Console.WriteLine(t)
        Next
        Console.ReadKey()
    End Sub
End Module

除了像你所做的那样建立文件扩展名关联之外，你还可以将文件拖放到可执行文件中相同的效果，或将您的可执行文件复制到（例如）C：\ Users \Default \ AppData \Roaming\Microsoft \Windows \ SendTo，这样当您右键单击文件时它将出现在上下文菜单中在资源管理器中

In addition to making a file extension association as you have done, you can also drop files onto the executable for the same effect, or copy your executable into (e.g.) C:\Users\Default\AppData\Roaming\Microsoft\Windows\SendTo so it will appear in the context menu when you right-click on a file in Explorer
