How avoid exception deserializing an invalid enum item?

问题 For simplicity purposes here, I will show my sample code using fruit. In actuality I am doing something more meaningful (we hope). Let say we have an enum: public enum FruitType { Apple, Orange, Banana } And a class: [Serializable] public class Fruit { public FruitType FruitType { get; set; } public Fruit(FruitType type) { this.FruitType = type; } } We can serialize and de-serialize it. Now, lets revise the enum, so that it is now: public enum FruitType { GreenApple, RedApple, Orange, Banana

I have an xml in which one of the elements has an attribute that can be blank. For e.g., <tests> <test language=""> ..... </test> </tests> Now, language is enum type in the classes created from the schema. It works fine if the language is specified, it fails to deserialize if it is blank (as shown in example). Edit: Code for deserialization: XmlSerializer xmlserializer = new XmlSerializer(type); StringReader strreader = new StringReader(stringXML); Object o = serializer.Deserialize(strreader); How can I handle this scenario You could declare the enum property as nullable: public Language?

I get this error after I created a class from my xsd file using the xsd.exe tool. So I searched the net and found a solution. Here is the link: http://satov.blogspot.com/2006/12/xsdexe-generated-classes-causing.html Problem is that this makes the code run, but somehow the deserialized data seems corrupt. I did what the site suggests and in the end the 2nd array dimension is always empty (see the comments of the site, somebody also had this problem). Question is, how do I solve this issue now? Is there another tool to create the xsd file? I tried Xsd2Code, without success. Thanks :-) Ajax You

I have a problem which I have been bashing my head against for the better part of three hours. I am almost certain that I've missed something blindingly obvious...
