Members with names ending on 'Specified' suffix have special meaning to the XmlSerializer: they control serialization of optional ValueType members and have to be of type System.Boolean.
Here is a test class to generate the exception where I explicitly declared the 'generating_bugSpecified' Member to integer.
[System.Xml.Serialization.XmlIncludeAttribute(typeof(TestBugg))]
public class TestBug
{
[System.Xml.Serialization.XmlAttributeAttribute()]
public System.Int32 generating_bug;
/// <remarks/>
[System.Xml.Serialization.XmlIgnoreAttribute()]
public int generating_bugSpecified;
}
Try serializing this above class with XmlSerializer, ie.
TestBug bug = new TestBug();
bug.generating_bug = 10;
SerializeObjectToFile(bug,"c:\\temp\\msg.txt");
public void SerializeObjectToFile( object objectToSerialize, string path)
{
File.Delete(path);
FileStream fs = new FileStream(path, FileMode.OpenOrCreate, FileAccess.Write);
System.Xml.Serialization.XmlSerializer x = new System.Xml.Serialization.XmlSerializer(objectToSerialize.GetType());
x.Serialize(fs, objectToSerialize);
fs.Close()
}
You will find the following exception raised.
System.InvalidOperationException: There was an error reflecting type 'WindowsApplication1.TestBug'. ---> System.InvalidOperationException: Member 'abug_genSpecified' of type System.Int32 cannot be serialized. Members with names ending on 'Specified' suffix have special meaning to the XmlSerializer: they control serialization of optional ValueType members and have to be of type System.Boolean.
