怎么自动打开然后关闭文件夹中的所有文件

“打开文件后你打算做什么？读/写？”没关系。
我想打开然后逐个关闭文件。
怎么做？算法是：1。
选择文件夹2。
选择文件末尾，例如* .txt3。
在结尾* .txt4的文件夹中自动打开第一个（按字母顺序排序）文件。
分析此文件（例如，计算行数），在Logging AlphaNumeric .5中编写报告。
自动关闭此文件。
自动打开，分析和关闭第二个文件，对于所有文件一个接一个。“在VEE示例中，在Concept文件夹中有tofrom1和tofrom2 VEE程序，在DotNet中有一些SelectFiles，SelectFolders，FileInfo，FileOperations。”我有
没有找到如何打开/分析/关闭文件一个接一个。

"
What are you trying to do after open the files? Read/Write?
"

It does not matter. I want to open and then close the files one by one. How to do it?
The algorithm is:
1. Selecting the folder
2. Selecting the end of files, for example, *.txt
3. Automatic open first (Alphabetical sorting) file in folder with end *.txt
4. Analysis of this file, for example, counting the number of rows, write a report in Logging AlphaNumeric .
5. Automatic close this file.
6. Automatic open, analysis and close second file and so for all files one by one.

"
In VEE examples, in Concept folder there are tofrom1 and tofrom2 VEE program, in DotNet there are a few SelectFiles, SelectFolders, FileInfo, FileOperations.
"

I have not found there how open/analysis/close files one by one.

1.选择文件夹2。
选择文件结尾，例如* .txtTo允许用户选择文件，你可以使用数据>对话框>文件名选择选择要允许用户选择文件夹，你可以使用数据>对话框>文本输入，用户必须输入
在手动文件夹路径中。
如果不是误以为.NET有浏览器文件夹对话框，但我还没有尝试过。要以编程方式查找文件夹路径，请在函数＆amp;
对象浏览器>内置函数>系统信息，有一些方法，例如
baseName，dirName，programName等可以帮助您以编程方式构造文件夹名称。
查看各个功能描述以获取详细信息。
如果文件夹/文件名始终是固定的，只需使用常量文本对其进行硬编码。菜单系统>目录，路径提供的功能也很少。
在文件夹中自动打开（按字母顺序排序）文件，结尾为* .txt >>如果文件名上有图案，则会更容易。
您可以以编程方式构造文件名。
如果文件名是随机的，那么可以使用菜单系统>目录>获取文件来获取所有文件，然后您将检查文件扩展名是否为.txt。
否则，您可以使用覆盖的Get Files方法传入搜索模式。
分析此文件，例如，计算行数，在Logging AlphaNumeric中编写报告。>>在上述示例中，它演示了如何使用To / From File对象写入/读取文件。
在tofrom1.vee中，它显示了如何创建文件，如何读取文件以及如何写入数据。
To / From File具有控制输入，您可以在其中以编程方式传递文件名。
我没有做你需要的，所以我不确定什么是最有效的方式。
此刻，也许可以逐行阅读文本并增加计数器。
或者也许使用.NET流阅读器，逐行读取，然后递增计数器，如果我只需要知道行的总数。
我没有例子，如果其他人有并且可以分享。
自动关闭此文件。>>如果您使用的是To / From文件，只需添加一个事务Execute Close。
如果是.NET流阅读器，只需执行close.6。
自动打开，分析和关闭所有文件的第二个文件。>>只需循环，处理文件名。
取决于你正在使用什么样的循环，For Each，For count，或者手动跟踪文件名。希望这会有所帮助。-mk

  1. Selecting the folder
2. Selecting the end of files, for example*.txt

To allow user to choose the file, you may use Data > Dialog Box > File Name selectionlection

To allow user to choose folder, you may use Data > Dialog Box > Text Input where user has to type in the folder path manually. If not mistaken .NET has browser folder dialog but I have not tried that yet.

To programmatically find a folder path, in Function & Object Browser > Built-in Functions > System Information, there are a few method e.g. baseName, dirName, programName and etc which can help you to construct the folder name programmatically. Look into individual functions description for details.

If the folder/file name is always fixed, just use a constant Text to hardcode it.

Menu System > Directory, Path provide few functions as well.

3. Automatic open first (Alphabetical sorting) file in folder with end *.txt
>> If there is a pattern on the file name, then it will be easier. You can construct the file name programatically. If the file name is random, then can use menu System > Directory > Get Files to get all files, then you will have do to some checking if the file name extension is .txt. Or else you can use the overriden Get Files method to pass in a search pattern.

4. Analysis of this file, for example, counting the number of rows, write a report in Logging AlphaNumeric .
>> In the examples mentioned, it demonstrated how to write/read files using To/From File object. In tofrom1.vee, it shows how to create a file, how to read a file, and how to write data. To/From File has control input where you can pass File Name programatically. I have not did what you need so I am not sure what is the most efficient way. At the moment, maybe reading text line by line and increment the counter will do. Or maybe use .NET stream reader, read line by line, then increment the counter, if I need to know just the total number of line. I have no examples, if other has and can share.

5. Automatic close this file.
>> If you are using To/From file, just add a transaction Execute Close. If .NET stream reader, just execute close.

6. Automatic open, analysis and close second file and so for all files one by one.
>> Just do a looping, process the file name. Depends on what kind of loop you are using, For Each, For count, or track the file name manually.

Hope this helps.

谢谢你，changmeikuan。我在菜单系统中找到了.NET的所有操作。

  Thank you, changmeikuan.

I found all the operations with .NET for my problem in menu System.
