XMLSerializer

Hello everyone, Two questions about XMLSerializer. http://msdn.microsoft.com/en-us/library/system.xml.serialization.xmlserializer(VS.80).aspx 1. It is mentioned -- "To increase performance, the XML serialization infrastructure dynamically generates assemblies to serialize and deserialize specified types." What means the assemblies? 2. For the following sample, why creates two XMLSerializer instances, one is s and the other is ser?
Hashtable serializers = new Hashtable();
// Use the constructor that takes a type and XmlRootAttribute.
XmlSerializer s = new XmlSerializer(typeof(MyClass), myRoot);// Implement a method named GenerateKey that creates unique keys
// for each instance of the XmlSerializer. The code should take
// into account all parameters passed to the XmlSerializer
// constructor.
object key = GenerateKey(typeof(MyClass), myRoot);// Check the local cache for a matching serializer.
XmlSerializer ser = (XmlSerializer)serializers[key];
if (ser == null)
{
ser = new XmlSerializer(typeof(MyClass), myRoot);
// Cache the serializer.
serializers[key] = ser;
}
else
{
// Use the serializer to serialize, or deserialize.
}thanks in advance, George

They are two different samples as discussed in the text preceding the sample code section of the documentation. See the text and the use of the word "otherwise".

1.The XML Serializer creates an XML serialization assembly per type that you are trying to Serialize\DeSerialize. you can increase performance using precompiled serialization assembly that you are creating using the sgen.exe utility. 2.Sorry but i dont have a clue for this one.

Thanks nissims, 1. You mean CLR will create a new assembly (DLL/EXE) for each type I need to serialize, other than using existing CLR assembly (e.g. System.XML.dll)? For example, when I want to serialize type Foo, CLR will create something like FooSerialize.dll? 2. The additional dynamically created assembly will be deleted when I unload the Appdomain? And next time when I run my assembly again, each of the dynamically created assemblies will be created again? 3. My assembly will invoke the dynamically created assemblies to do serialize/deserialize? 4. "using precompiled serialization assembly that you are creating using the sgen.exe utility" -- do you have any samples or reference documents? regards, George

You misunderstand my points and my English is not good. :-) Any comments to? http://www.codeproject.com/script/Forums/View.aspx?fid=1649&msg=2550767[^] regards, George
