Question

我正在尝试反序列化以下XML：

@"<Activity type=""WOActivity"">
<ActionID>1</ActionID> 
<ActionLog></ActionLog> 
<ActionLogSummary>Add subcomponent</ActionLogSummary> 
<UserID></UserID> 
<FlexFields> 
    <FlexField mappedTo=""STATUS"" id=""0"">WAPPR</FlexField> 
    <FlexField mappedTo=""WOSEQUENCE"" id=""0"">10</FlexField> 
    <FlexField mappedTo=""OWNERGROUP"" id=""0"">V-PSB-DE-HLC-HWSUPPORT</FlexField> 
</FlexFields>

我也有以下类，它是由xsd：

}

我做了一个单元测试，但它失败了，因为所有元素都是null（第二个断言）。 type属性被反序列化了。

可能出现什么问题？

PS：我曾尝试将命名空间“http://b2b.ibm.com/schema/B2B_CDM_Incident/R2_2”添加到序列化程序中但没有成功...

PS2：序列化似乎对这个类很好用

感谢。

    <ActionID>1</ActionID> 
    <ActionLog></ActionLog> 
    <ActionLogSummary>Add subcomponent</ActionLogSummary> 
    <UserID></UserID>

    </FlexFields> 
 </Activity>";
    var serializer = new XmlSerializer(typeof (Activity), new XmlRootAttribute("Activity"));
            var first = (Activity)serializer.Deserialize(new XmlTextReader(new StringReader(result)));
            Assert.AreEqual("WOActivity", first.type);
            Assert.AreEqual("Add subcomponent", first.ActionLogSummary);
            Assert.IsNotNull(first.FlexFields);
            Assert.AreEqual(4, first.FlexFields.Count());

Answer 1

只需将根元素放入正确的命名空间：

string xml = @"<Activity type=""WOActivity""
       xmlns=""http://b2b.ibm.com/schema/IS_B2B_CDM/R2_2"">
    ...
    </Activity>";

请注意，因为名称空间是继承的，所以其他所有内容也都使用该元素。

这样可行：

var ser = new XmlSerializer(typeof(Activity));
var activity = (Activity)ser.Deserialize(new StringReader(xml));
System.Console.WriteLine(activity.ActionID);
System.Console.WriteLine(activity.ActionLogSummary);
System.Console.WriteLine(activity.type);

带输出：

1
Add subcomponent
WOActivity

在其他情况下，您可能需要引用多个名称空间，或多次提及相同的名称空间。然后声明别名会很有用;以下内容与本答案中的第一个示例在语义上相同：

string xml = @"<b2b:Activity type=""WOActivity""
       xmlns:b2b=""http://b2b.ibm.com/schema/IS_B2B_CDM/R2_2"">
<b2b:ActionID>1</b2b:ActionID> 
<b2b:ActionLog></b2b:ActionLog> 
<b2b:ActionLogSummary>Add subcomponent</b2b:ActionLogSummary> 
              ...
              </b2b:Activity>";

唯一的区别是我们现在可以使用b2b:作为任何元素的前缀，作为说xmlns=""http://b2b.ibm.com/schema/IS_B2B_CDM/R2_2""的替代方法。另请注意，基于 alias 的命名空间不继承，与xmlns=命名空间不同。

Answer 2

删除两个生成的行：

[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true, Namespace = "http://b2b.ibm.com/schema/IS_B2B_CDM/R2_2")]
[System.Xml.Serialization.XmlRootAttribute(Namespace = "http://b2b.ibm.com/schema/IS_B2B_CDM/R2_2", IsNullable = false)]

C＃反序列化null元素
