C＃的反序列化null元素

我正嘗試反序列化下面的XML：C＃的反序列化null元素

@"<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>

從來就也下面的類，這是由所產生的xsd：

我做了一個單元測試，但因爲所有的元素都是null（第二個斷言），所以失敗了。 type屬性反序列化就好了。

什麼可能是錯誤的？

PS：從來就試圖命名空間「http://b2b.ibm.com/schema/B2B_CDM_Incident/R2_2」添加到串行器，但沒有成功...

PS2：序列化似乎是工作就好了該類

感謝。

   string result = @"<Activity type=""WOActivity""> 
    <ActionID>1</ActionID> 
    <ActionLog></ActionLog> 
    <ActionLogSummary>Add subcomponent</ActionLogSummary>

    <FlexFields> 
     <FlexField mappedTo=""STATUS"" id=""0"">WAPPR</FlexField>

     <FlexField mappedTo=""OWNERGROUP"" id=""0"">V-PSB-DE-HLC-HWSUPPORT</FlexField> 
    </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());

Definetely它是與命名空間... 刪除的命名空間中的聲明，類定義的伎倆，但我還是想知道，然後，聲明XL或串行器的正確方法是什麼，以便它能與那個確切的類定義一起工作。謝謝 –

這甚至不應該反序列化（它應該拋出一個錯誤）;命名空間'http：// b2b.ibm.com/schema/IS_B2B_CDM/R2_2'沒有在根元素 –

只要把根元素到正確的命名空間：

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

注意，因爲命名空間是繼承，其他的一切也使用該元素。

這則作品：

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);

與輸出：

1 
Add subcomponent 
WOActivity

在其他情況下，你可能需要參考多個命名空間，或提相同的命名空間多次。然後聲明一個別名會很有用;以下是語義上的第一個例子中這樣的回答：

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>";

有了，我們現在可以在任何元素上使用b2b:作爲前綴作爲替代說法xmlns=""http://b2b.ibm.com/schema/IS_B2B_CDM/R2_2""唯一的區別。還要注意，別名基於名稱空間是不是繼承，不像xmlns=名稱空間。

只是刪除生成的兩個行：

[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)]

上聲明，這就是我所做的，它工作正常。只是想知道我在xml中丟失了什麼。 012ks Tks –
