如何将一个类序列化为字段 [英] How to serialize a class as field

问题描述

示例:

public class MYELEMENT
{
    public string value;
}

上面将产生类似以下内容:

The above would produce something like the following:

<MYELEMENT><value>string</value></MYELEMENT>

就我的目的而言，我需要以下内容:

For my purposes I need the following:

<MYELEMENT>string</MYELEMENT>

我正在创建一个元素数组，该数组保留从外部源序列化的原始元素的顺序.

I am creating an array of elements that preserves the order of the original elements serialized from an external source.

public class MYROOT
{
    [XmlElement(typeof(MYELEMENT1))]
    [XmlElement(typeof(MYELEMENT2))]
    [XmlElement(typeof(MYELEMENT3))]
    public object[] nodes { get; set; }
}

每种类型可能有一个或多个元素，可以以任何顺序出现.因此，每个元素都表示为一个类对象.

所编写的代码可以正常工作，只不过反序列化此代码

There may be one or more elements of each type that can appear any order. Therefore, each element is represented as a class object.

The code, as written, works fine except that Deserializing this

<MYELEMENT>1</MYELEMENT>

序列化时会产生以下内容

produces the following when Serializing it out

<MYELEMENT />

目前正确，因为没有子元素.

是否可以使用XML属性或其他方法来产生所需的内容?

这样的东西

Which is correct at the moment, because there is no sub-element.

Is there an XML attribute or other method that can be applied to produce what I need?

Something like this

public class MYELEMENT
{
    [this is the elements value]
    public string value;
}

或这个

or this

[this is a wrapper for the real element]
public class Foo
{
    public string MYELEMENT { get; set; }
}

Thanks!

推荐答案

解决方案是使用[XmlText()]以获得正确的结果.

示例:

The solution is to use [XmlText()] for correct results.

Example:

public class MYELEMENT1
{
    [XmlText()]
    public string value;
}

public class MYELEMENT2
{
    [XmlText(typeof(int))]
    public int value;
}

序列化的结果:

Result of Serializing :

<MYELEMENT1>string</MYELEMENT1>
<MYELEMENT2>1</MYELEMENT2>

我建​​议避免在此级别上进行手动"序列化，并使用 Data Contracts .

这种方法是最非侵入性的，最容易实现，同时最灵活.

请在我倡导这种方法的地方查看我过去的答案:
如何在我的表单应用程序? [ ^ ]，
创建属性文件... [反序列化json字符串数组 [

I would recommend to avoid "manual" serialization on this level and use Data Contracts.

This approach is most non-intrusive, easiest to implement and most flexible at the same time.

Please see: http://msdn.microsoft.com/en-us/library/ms733127.aspx[^].

Please also see my past answers where I advocate this approach:
