问题描述

我正在开发一个新的WPF应用程序，其中大部分用户输入一些数据，并根据该输出显示输出。我想存储输入数据。



输入数据包含

1图片，

30个文字叮咬



有人建议我使用最好的数据库，我可以使用一些示例代码。

I am developing a new WPF application where mostly user inputs some data and output is shown based on that. I want to store the input data.

Input data contains
1 Image,
30 text stings

Can someone suggest me with the best database that I can use with some sample code.

推荐答案

你需要拥抱分离关注的。 WPF如何与保存数据相关？数据是一个问题，UI是另一个问题。而且你真的需要尽可能地将UI与编程系统的其他方面分开。



您可以通过多种方式存储数据。首先，随着您的数据量很小，您可以使用带有序列化的单个文件，使用XML，JSON或二进制文件作为数据媒体。请参阅：

http://en.wikipedia.org/wiki/Serialization [< a href =http://en.wikipedia.org/wiki/Serializationtarget =_ blanktitle =New Window> ^ ]，

http://msdn.microsoft.com/en-us/library/7ay27kt9%28v=vs .110％29.aspx [ ^ ]。



在大多数情况下，数据合同是序列化的最佳方法：

http://msdn.microsoft.com/en-us/library/system.runtime.serialization.datacontractserializer%28v=vs.110%29.aspx [ ^ ]，

http://msdn.microsoft.com/en-us/library/system.runtime.serialization.json.datacontractjsonserializer%28v=vs.110%29.aspx [ ^ ]。



请参阅我过去的答案，我提倡这种方法：

如何在我的表单appl中使用XML文件的编写器和阅读器ication？ [ ^ ]，

创建属性文件...... [ ^ ]，

解析json字符串数组 [ ^ ]。



对于数据库，请查看以下选项：

http://en.wikipedia.org/wiki/Comparison_of_relational_database_management_systems [ ^ ]，

http://en.wikipedia.org/wiki/Comparison_of_object-relational_database_management_systems [ ^ ]。



您的选择取决于很多因素，包括成本，维护和您自己的品味。

You need to embrace separation of concerns. How can WPF be related to saving data? Data is one concern, UI is another one. And you really need to separate UI from other aspects of your programming system, as much as possible.

You can store data in many ways. First of all, with you minute volume of data, you can use a single file with serialization using XML, JSON or binary file for the media of your data. Please see:
http://en.wikipedia.org/wiki/Serialization[^],
http://msdn.microsoft.com/en-us/library/7ay27kt9%28v=vs.110%29.aspx[^].

In most cases, Data Contract is the best approach to serialization:
http://msdn.microsoft.com/en-us/library/ms733127%28v=vs.110%29.aspx[^],
http://msdn.microsoft.com/en-us/library/system.runtime.serialization.datacontractserializer%28v=vs.110%29.aspx[^],
http://msdn.microsoft.com/en-us/library/system.runtime.serialization.json.datacontractjsonserializer%28v=vs.110%29.aspx[^].

Please see my past answers where I advocate this approach:
How can I utilize XML File streamwriter and reader in my form application?[^],
Creating property files...[^],
deseralize a json string array[^].

For a database, review these options:
http://en.wikipedia.org/wiki/Comparison_of_relational_database_management_systems[^],
http://en.wikipedia.org/wiki/Comparison_of_object-relational_database_management_systems[^].

Your choice depends on many factors, including costs, maintenance, and your own taste.
