If you want to take control of your xml serialization then you have two options. The first (which might not be appropriate here) it to use the attributes in the System.Xml.Serialization namespace to exclude properties. If you really need to do determine what gets serialized at runtime this might not be the best course of action.

See <a href="http://msdn.microsoft.com/en-us/library/83y7df3e.aspx" rel="nofollow noreferrer">Attributes That Control XML Serialization</a>

The other way to do this is to implement the IXmlSerializable interface on your class and implement the ReadXml and WriteXml methods. This allows you to take control of exactly how your xml looks. See this question for additional info:

<a href="https://stackoverflow.com/questions/3109827/custom-xml-serialization">custom xml serialization </a>

However, as mentioned here <a href="https://stackoverflow.com/questions/641612/mixing-custom-and-basic-serialization">Mixing custom and basic serialization?</a> once you implement IXmlSerializable you are responsible for all the serialization logic for your type.

blocks|key|1899243|text|我会给出马丁·派克的答案。可以避免使用“指定”后缀的字段/属性的序列化。您应该在类中定义“*指定”属性，并将[XmlIgnoreAttribute()]应用于它们。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1899244|下面是一个示例：|1899245|[System.SerializableAttribute()]

I will extend answer of Martin Peck.
You can avoid serialization of the fields/properties with "Specified" suffix.
You should define that "*Specified" properties in your class and apply <code>[XmlIgnoreAttribute()]</code> to them.

Here is an example:

<pre><code>[System.SerializableAttribute()]
[System.Xml.Serialization.XmlTypeAttribute(Namespace = "http://yournamespace.com")]
public partial class YourObject
{
 private long sessionTimeoutInSecondsField;

 private bool sessionTimeoutInSecondsFieldSpecified;

 public long sessionTimeoutInSeconds
 {
 get
 {
 return this.sessionTimeoutInSecondsField;
 }
 set
 {
 this.sessionTimeoutInSecondsField = value;
 }
 }

 [System.Xml.Serialization.XmlIgnoreAttribute()]
 public bool sessionTimeoutInSecondsSpecified
 {
 get
 {
 return this.sessionTimeoutInSecondsFieldSpecified;
 }
 set
 {
 this.sessionTimeoutInSecondsFieldSpecified = value;
 }
 }
}
</code></pre>

</code></pre>

You can set "vehicleTypeFieldSpecified" = {true/false} to {serialize/omit} it;

<pre><code>advancedSearchRequest.vehicleTypeField = vehicleType.BIKE;
advancedSearchRequest.vehicleTypeFieldSpecified = true;
</code></pre>

Resulting SOAP message;

<pre><code>&lt;advancedSearchRequests&gt;
 &lt;vehicleType&gt;BIKE&lt;/vehicleType&gt;
 &lt;search&gt;abc&lt;/search&gt;
&lt;/advancedSearchRequest&gt;
</code></pre>

I've discovered that if a serializable Field/Property has a corresponding field of type Boolean having as a name the Field/Property name with "Specified" suffix, the XmlSerializer conditionally exclude that Field/Property from the serialization process. Nice!

So, I want to avoid the definition of those fields, and add them dynamically, at runtime...

Reading <a href="https://stackoverflow.com/questions/646258/how-can-i-add-dynamically-field-to-the-class-in-c">this</a>, I found an interesting interface <a href="http://msdn.microsoft.com/en-us/library/system.reflection.ireflect_members(v=VS.80).aspx" rel="nofollow noreferrer">IReflect</a>, which I can use to "emulate" dynamic fields which are used by the XmlSerializer instances to exclude certain fields.

Would this work?

我已经发现，如果可序列化的字段/属性具有相应的布尔型字段，其名称为带有“指定”后缀的字段/属性名称，则XmlSerializer有条件地将该字段/属性排除在序列化过程之外。好的!因此，我希望避免这些字段的定义，并在运行时动态地添加它们.阅读后，我发现了一个有趣的接口，它可以用来“模拟”XmlSerializer实例用来...
