如何过滤c＃中没有扩展名的文件 [英] How to filter files with NO extension in c#

问题描述

我尝试过OpenFileDialog1.Filter =设置十六进制文件（*。）| *。;

但它没有显示任何文件。我想在Openfiledialog浏览器中显示没有扩展名的文件，

请告诉我有蚂蚁的想法。

I tried OpenFileDialog1.Filter = "Setting Hex files (*.)|*.";
but it showing no files.I want to show files having no extensions during Openfiledialog browser,
please tell me having ant idea.

推荐答案

使用未改变的OpenFileDialog框是不可能的 - 它需要一个扩展名，并且windows会删除。。从文件结束，所以*。永远不会工作。



你可以这样做，如果你可以挂钩标准对话框（见这里： http://msdn.microsoft.com/en-us/library/ms646960（VS.85）.aspx [ ^ ]，约1/3在过滤器下面的方式）但是在C＃中为一个小功能做了很多工作！



你的Hex文件没有任何扩展名有什么好的理由？给它们一个像* .MyAppHex这样的名字或类似的东西然后过滤它们会容易得多。



如果你真的必须这样做，我会很想不使用标准盒子，但是自己重新创建它的功能 - 它可能比在标准对话框上实现挂钩要容易得多！

It''s not possible with an unaltered OpenFileDialog box - it expects an extension, and windows removes the "." from files end with it, so "*." will never work.

You could probably do it, if you can hook the standard dialog (see here: http://msdn.microsoft.com/en-us/library/ms646960(VS.85).aspx[^], about 1/3 the way down, under filters) but that''s a lot of work in C# for a small feature!

Is there any good reason why your Hex files have no extension? It would be a lot easier to give them a name like *.MyAppHex" or similar then filter for them.

If you really do have to do this, I would be tempted to not use the standard box at all, but re-create it''s features myself - it''s probably a lot easier than implementing the hooking on a standard dialog!
