如何获取txt文件的关联程序？ [英] How do I get the associated program for a txt file?

问题描述

您好，



我在尝试获取用户计算机上文本文件的默认应用程序时遇到问题。



我试过了

Hello,

I'm having issues trying to get the the default application for text files on a users machine.

I've tried

Microsoft.Win32.Registry.ClassesRoot.OpenSubKey("txtfile").GetValue("FriendlyTypeName")

但它总是返回标准窗口notepad.exe



这是错误的，因为在我的机器上.txt文件与Brackets.exe相关联，如果我双击txt文件就会加载。



I我需要知道应用程序，因为我有很多与其他程序相关的自定义文件扩展名，但文件是纯文本，因此可以在文本编辑器中查看。



我应该在注册表中的其他地方吗？



谢谢

But it always returns the standard windows notepad.exe

This is wrong because on my machine .txt files are associated with Brackets.exe and this is what loads if I double click on a txt file.

I need to know the application because I have a lot of custom file extensions that are associated to other programs, but the files are plain text so can be viewed in a text editor.

Is there somewhere else in the registry I should be looking?

Thanks

推荐答案

好吧，你可以使用 FindExecutable [ ^ ]

Well, you could use FindExecutable[^]

[DllImport("shell32.dll")]
static extern int FindExecutable(string lpFile, string lpDirectory, [Out] StringBuilder lpResult);
...
    StringBuilder sb = new StringBuilder(1024);
    int i = FindExecutable(@"D:\Temp\AAAA.txt", null, sb);
    Console.WriteLine(sb.ToString());
