有没有办法在应用程序设置中使用字典或xml？ [英] Is there a way to use a dictionary or xml in the Application Settings?

问题描述

我必须在应用程序设置中存储一个复杂的类型。我认为将其存储为XML将会工作得最好。

问题是我不知道如何存储XML。我更喜欢将其存储为托管XML，而不是仅使用原始XML字符串在每个访问上解析它。我设法将设置的类型列设置为XDocument，但是我无法设置其值。

有没有办法在应用程序设置中使用XDocument或XML？

更新

我找到了一种方法，只需使用xml编辑器编辑.settings文件。

我将其更改为自定义可序列化字典，但是当我尝试访问setting-property（我将其设置为默认值的序列化表示）时，我收到以下错误。 / p>

 属性设置无法从其默认值创建。 
错误消息：XML文档中有错误（1，41）。 
  

任何想法将不胜感激。

解决方案

我做了什么（即使我不喜欢这么多 - 但是工作）是：

我创建了简单的可序列化的我的类值：

 < Xml.Serialization.XmlRoot（Rooms）> _ 
公共课室：继承人（$）
结束类
 
< Serializable（）> _ 
公共课室
私人m_Room As String 
公共房间（）As String 
获取
返回m_Room 
结束获取
设置（ ByVal值As String）
 m_Room = value 
结束集
结束属性
 
私有m_Sections作为新列表（部分）
公共ReadOnly属性部分）作为列表（部分）
获取
返回m_Sections 
结束获取
结束属性
结束类
 
< Serializable（）> ; _ 
公共类节
私有m_Section As String 
公共属性Section（）As String 
获取
返回m_Section 
结束Get 
 Set（ ByVal值As String）
 m_Section = value 
结束集
结束属性
结束类
  

然后在.settings文件中，我将设置的类型（使用xml编辑器打开的.setting文件）编辑为房间的全名（即MyProject.Rooms）。
然后我做了一个样本反序列化示例，并将其复制到.settings编辑器中的值字段以具有默认值。它的效果很好
确实不是字典，但是我仍然可以在Rooms类和内部字典中实现（通过Room.Room返回Sections。

任何好的想法仍然很受欢迎，我仍然在寻找一种方法来在.settings文件中使用 IDictinoary 。

I have to store a complex type in the application settings. I thought that storing it as XML would work best.

The problem is I don't know how store XML. I prefer to store it as a managed XML rather than using just a string of raw XML having to parse it on each access. I managed to set the Type column of the setting to XDocument, but I was unable to set its value.

Is there a way to use XDocument or XML in application settings?

Update

I found a way, simply by editing the .settings file with the xml editor.

I changed it to a custom serializable dictionary, but I get the following error when I try to access the setting-property (I set it to a serialized representation of the default value).

The property 'Setting' could not be created from it's default value.
Error message: There is an error in XML document (1, 41).

Any ideas will be appreciated.

解决方案

What I did (even I don't like so much - but works) is:

I created simple serializable classes of my values:

<Xml.Serialization.XmlRoot("Rooms")> _
Public Class Rooms : Inherits List(Of Room)
End Class

<Serializable()> _
Public Class Room
    Private m_Room As String
    Public Property Room() As String
        Get
            Return m_Room
        End Get
        Set(ByVal value As String)
            m_Room = value
        End Set
    End Property

    Private m_Sections As New List(Of Section)
    Public ReadOnly Property Sections() As List(Of Section)
        Get
            Return m_Sections
        End Get
    End Property
End Class

<Serializable()> _
Public Class Section
    Private m_Section As String
    Public Property Section() As String
        Get
            Return m_Section
        End Get
        Set(ByVal value As String)
            m_Section = value
        End Set
    End Property
End Class

Then in the .settings file, I edited the type of the setting (the .setting file opened with the xml editor) to full name of Rooms (i.e. MyProject.Rooms). Then I made myself a sample deserialized sample and copied it to the value field in the .settings editor to have a default value. it works great. It is indeed not a dictionary, but I could still implement in the Rooms class and internal dictionary (that returns Sections by Room.Room.

Any good ideas are still welcommed, I am still looking for a way to be able to use IDictinoarys in the .settings file.

Besides, I opened a connection for it, please be kind and vote!
