XSD.EXE生成的类不会序列化的默认值属性 [英] xsd.exe generated classes don't serialize default value attributes

问题描述

我有一个XSD架构由XSD.EXE产生一些的.cs文件。

I have few .cs files generated by xsd.exe by a XSD schema.

我的问题是，当我尝试序列这些类XML，其值匹配XSD架构中定义的默认值没有被序列化的属性。

My problem is that when i try to serialize those classes to xml, the attributes whose values match the default values defined in the xsd schema are not being serialized.

我发现，当我删除 [System.ComponentModel.DefaultValueAttribute（typeof运算（小于我的问题就解决了; SOMETYPE>），< someValue中方式>），用以表示默认字段成员]
属性。

I found out that my problem is solved when i remove [System.ComponentModel.DefaultValueAttribute(typeof(<someType>), "<SomeValue>")] attribute for the member representing a default field.

所以我的问题是不是有更优雅的方式去做这个？ ？例如有没有什么办法可以指定我想要的默认值进行反正序列

So my question isn't there more elegant way to do this? For example is there any way to specify that I want the default values to be serialized anyway?

推荐答案

短的版本是：是。这看起来是最简单的方法。

The short versions is: yes. it looks like that is the simplest approach.

我试过了显而易见的东西（尤其是 *指定和 ShouldSerialize * 模式，的XmlSerializer 支持，还 ISNULLABLE ），它只是不断不包括价值。

I've tried the "obvious" things (in particular the *Specified and ShouldSerialize* patterns that XmlSerializer supports, but also IsNullable) and it just keeps on not including the value.

接下来的选择是，要么的IXmlSerializable （其中是平原硬），或 XmlAttributeOverrides （重复劳动） - 两者都不是特别诱人这里。我不知道你目前的办法是减少工作？你当然可以简单地导出WSDL和编辑删除默认的（和编辑后的版本生成）

The next options would be either IXmlSerializable (which is plain hard), or XmlAttributeOverrides (a duplication of effort) - neither of which is particularly enticing here. I wonder if your current approach is less work? You could of course simply export the WSDL and edit that to remove the default (and generate from the edited version).

顺便说一句 - 如果这是WCF，有在 [数据成员（EmitDefaultValue = ...）] 的确实的控制这一点;也许他们加入这个作为一个功能提出要求？

As an aside - if this was WCF, there is the [DataMember(EmitDefaultValue = ...)] that does control this; maybe they added this as a feature request?
