how to ask XSD.exe to generate proper class for me, so that i can create a fine XML

问题

I have created an XSD file from Visual Studio 2010,

Then I use xsd /c mydemo.xsd to generate class for me, so that I can create a XML file at runtime.

However, when I use that class, fill in some values, and serialize the object, the XML file does not look nice to me.

Here is my XSD file Click here to see

What I expected the XML file to be is Click here to see (Generated from Visual Studio "Sample XML")

But when I try to serialize it, the XML file is like this CLick here to see

The format is totally different

e.g

Expecting:

<ColumnInfo> 
  <Column Type="Type1" DisplayValue="DisplayValue1" Key="Key1"/> 
  <Column Type="Type2" DisplayValue="DisplayValue2" Key="Key2"/> 
  <Column Type="Type3" DisplayValue="DisplayValue3" Key="Key3"/> 
</ColumnInfo>

but the generate result is like this:

<columnInfoField>
  <ColumnType>
    <displayValueField>Display value for key 1</displayValueField>
    <keyField>key1</keyField>
    <typeField>string</typeField>
  </ColumnType>
  <ColumnType>
    <displayValueField>Display value for key 2</displayValueField>
    <keyField>key2</keyField>
    <typeField>int</typeField>
  </ColumnType>
  <ColumnType>
    <displayValueField>Display value for key 3</displayValueField>
    <keyField>key3</keyField>
    <typeField>long</typeField>
  </ColumnType>
</columnInfoField>

And the code I implement to serialize the report is :

http://msdn.microsoft.com/en-us/library/ms731073.aspx

DataContractSerializer dcs = new DataContractSerializer(typeof(Report));
using (XmlDictionaryWriter xdw = XmlDictionaryWriter.CreateTextWriter(File.Create(@"C:\demo\schema\output.xml"), Encoding.UTF8))
{
  dcs.WriteObject(xdw, report);
}

Not sure why I cannot use "XmlSerializer", when I use it, it will complain about cannot cast array type something...

Unable to generate a temporary class (result=1).
error CS0030: Cannot convert type 'ColumnValueType[]' to 'ColumnValueType'
error CS0029: Cannot implicitly convert type 'ColumnValueType' to 'ColumnValueType[]'

So, does anyone can give me some suggestion, how can i fix my XML format???

回答1:

There is a bug on xsd.exe - look at this blog-post: http://satov.blogspot.com/2006/12/xsdexe-generated-classes-causing.html

回答2:

The data contract serializer has different rules that the XmlSerializer. Why don't you try the XmlSerializer first and then see if the output is "correct".
