问题描述
是否有更好的方式来读取和写入文本而不是这样做？我可以不做其他事情，而不是让用户能够写入文本文件，或者像我对此做的那样是给它一个独特的扩展。这是使用保存文件和打开文件选项的唯一方法。
Is there better way to read and write a text instead of doing it this way? Can I not do something else instead of giving the user the ability to write to text file or like what i did with this one is give it a unique extension. Is this the only wy of using save file and open file options.

推荐答案
您是否只想拥有持久数据？如果是这样，有很多选项。
如果您有很多用户，我建议您使用关系数据库，例如SqlLite，SqlServer或MySql。
如果你有一个用户，这可能没有必要。您可能只需要将数据导出到文件。有许多数据格式通常足以满足您的应用程序。常见的包括CSV和XML。
但是，如果你要求更多的代码更少......重复，我建议使用迭代;类似这样的事情：
Are you looking just to have persistent data? If so, there are a number of options.
If you have many users, I recommend looking into using a relational database, such as SqlLite, SqlServer, or MySql.
If you have a single user, this may not be necessary. You may just need to export data to a file. There are a number of data formats that would typically suffice for your application. Common ones include CSV and XML.
However, if you are asking more along the lines of making your code a bit less...repetitive, I would recommend using iteration; something like this:
For Each ctrl As Control In Form1.Controls
If ctrl.GetType() = GetType(TextBox) Or ctrl.GetType() = GetType(ComboBox) Then
objWriter.WriteLine(ctrl.Text)
End If
Next
您可以对Form2使用相同的代码，甚至可以迭代多个表格。
当然，您可能想要替换WriteLine具有不同功能的代码，具体取决于您是否更改导出方式data。
You could use the same code for Form2, or even iterate over a number of Forms.
Of course, you may want to replace the WriteLine code with a different function, depending on whether you change how you export the data.
我将数据绑定到XML数据源。我会附加和事件到最后一个控件，一个改变或类似的东西将保存我的整个数据源。
I would data bind my controls to an XML data source. I would attach and event to the last control, an on change or something like that which would save my entire data source.
