You can only Serialise concrete types. This is an annoying limitation of Serialization and one that means you must consider your Design Pattern before you implement any code. 
 
If possibe, you should serialise the contrete class that underlies then ImyItem to get it to work.

Hi, 
 
I am trying to DE-serialize an object, &nbsp;but when i attempt to do so, i get the error: &nbsp;&quot;Cannot serialize member 'items' &nbsp;of type 'ImyItem' &nbsp; because it is an interface. &nbsp;The class member it is referring to is ; 
 
public List&lt;ImyItem&gt; items { 
&nbsp; &nbsp; get { return this._items; } 
&nbsp; &nbsp; set { this._items = value; } 
} 
 
the interface 'ImyItem' defines the member variables and a few methods for the 'my'Item' objects. &nbsp;Why am i getting this error on deserialization? &nbsp;The code to deserialize &nbsp;that i am using is; 
 
System.IO.StreamReader sr = new System.IO.StreamReader(openFileDialog1.FileName); 
&nbsp; &nbsp; XmlSerializer ser = new XmlSerializer(typeof(WS.MyClass)); 
&nbsp; &nbsp; &nbsp; &nbsp; MyClass ob = (MyClass)ser.Deserialize(sr); 
 
&nbsp; &nbsp; &nbsp; &nbsp; System.console.writeline(ob.name.tostring()); 
&nbsp; &nbsp; &nbsp; &nbsp; sr.Close(); 
 
 
Any help with this would be greatly appriciated!!

&quot;Cannot serialize because it is an interface.&quot; exception message.

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).

Extensible Markup Language (XML) refers to the encoding of documents such that they can be read by both machines and humans. XML documents use tags to show the beginning and end of a set of data. XML is used extensively on websites to show volumes of data, and is the default for a number of office productivity suites. This topic includes discussions of XML-related technologies, such as XQuery (the XML Query language), XPath (the XML Path language), XSLT (eXtensible Stylesheet Language Transformations), XLink (the XML Linking language) and XPointer (the XML Pointer language).
