c#通过索引打开文件-Metastock数据文件 [英] c# open files through index - metastock data files

问题描述

大家好，
我正在寻求有关在程序中打开文件的帮助.要打开数据文件，我通常会使用OpenFileDialog()和FileStream()，效果很好，但是...
我正在尝试加载一些元数据数据文件，但它们由名为master.dat的文件索引. Master.dat是我已经解析出的旧格式，它提供了目录中其他文件(F * .dat)表示的索引.然后，我可以打开正确的F * .dat并检索O，H，L，C数据.但这是到达我想要的地方的两步过程.
例子...第一次打开目录->
F1.dat
F2.dat
.
.
F50.dat
Master.dat
-我必须先打开Master.dat才能找到我要查找的F * .dat.我解析Master.dat的方式看起来像这样(不一定按字母顺序.

文件名，股票代号，长名称，第一个数据，最后一个数据
F1.dat，MSFT，Microsoft，24/9/1999、27/9/2010
F2.dat，CAM，Cameron Ent，1/1/2005，27/9/2010
.
.
F50.dat，APPL，Apple Comp，24/9/1999、27/9/2010

然后，我打开相应的F * .dat文件以获取所需的数据.

我想做的是让OpenFileDialog自动打开Master.dat文件，然后列出上面显示的内容(通常在该位置看到这些文件)，然后我可以直接打开所需的原始文件.我已经整理出索引代码，我只需要打开目录并自动加载master.dat即可显示索引，而不是实际的文件名.
在此先感谢

Hi all,
I''m chasing some help with opening files in my program. To open a data file I would normally use OpenFileDialog() and FileStream() which works great but...
I am trying to load some metastock data files but they are indexed by a file called master.dat. Master.dat is in an old format which I have parsed out and it gives an index of what the other files (F*.dat) represent in the directory. I can then go and open the correct F*.dat and retrieve the O,H,L,C data. But this is a two step process to get to where I want.
Example... open the directory the first time->
F1.dat
F2.dat
.
.
F50.dat
Master.dat
- I have to open Master.dat first to find out which F*.dat I''m looking for. The way I parsed out Master.dat looks something like this (not necessarily in alphabetical order.

Filename, Ticker, Long Name, First Data, Last Data
F1.dat, MSFT, Microsoft, 24/9/1999, 27/9/2010
F2.dat, CAM, Cameron Ent, 1/1/2005, 27/9/2010
.
.
F50.dat, APPL, Apple Comp, 24/9/1999, 27/9/2010

I then go and open the corresponding F*.dat file to get the data I want.

What I''d like to do is have the OpenFileDialog automatically open the Master.dat file and then list the contents shown above where I''d normally see the files, I can then directly open the stock file I want. I''ve sorted out the indexing code I just need someway of opening a directory and the master.dat loading automatically to show the index, not the actual file names.
Thanks in advance

推荐答案

我认为您无法获得OpenFileDialog来做到这一点.

您可以做的是创建自己的对话框，如果需要的话，可以模仿OFD的外观，其中可能包含显示Master.dat内容的ListBox或ListView.

然后处理doubleclick事件以加载被单击的F * .dat文件.

I do not think that you can get the OpenFileDialog to do that.

What you can do is create your own dialog, mimic the appearance of OFD if you want, probably containing a ListBox or ListView that would display the contents of Master.dat.

Then handle the doubleclick event to load the F*.dat file that was clicked.
