I created some code from an XSD-schema-file using CodeDOM:
XmlSchemaImporter importer = new XmlSchemaImporter(schemas);
CodeNamespace code = new CodeNamespace(targetNamespace);
XmlCodeExporter exporter = new XmlCodeExporter(code);
foreach (XmlSchemaElement element in schema.Elements.Values)
{
XmlTypeMapping mapping = importer.ImportTypeMapping(element.QualifiedName);
exporter.ExportTypeMapping(mapping);
}
Now within my post-processing I realized that this code will generate properties like this:
bool prop1Field;
/// <remarks/>
[System.Xml.Serialization.XmlElementAttribute(Order=0)]
public bool Prop1
{
get
{
return prop1Field;
}
set
{
prop1Field = value;
}
}
But I want the generator to simply produce fields instead. Is there a way to achieve this? I know xsd.exe
also produces fields when using the /f
-argument.
EDIT: Afterwards I want to replace those by auto-properties. To do so with the current approach I´d have to delete the backing-field from the property and all its occurences within the generated code. If CodeDOM however generates a public
field in the first place all I had to do is to delete this field, create a new property with the same name using CodeSnippedTypeMember
as shown in this answer. Thus I won´t need to search the codes for occurences of the private backing-field and replace them by calls to the property.
No, there´s no option to be set to allow this as it shouldn´t matter for consuming code if your attribute is a field or a property (assuming we don´t use reflection) and public fields are considered bad practice.
Anyway I found a way to achieve this by copying all the comments and attributes of the property to the private backing-field and make the field public. However remember that doing so is mostly a bad design-idea.
public void Process(CodeNamespace code, XmlSchema schema)
{
foreach (var type in code.Types.Cast<CodeTypeDeclaration>().Where(x => !x.IsEnum))
{
var result = new List<CodeMemberField>();
var properties = type.Members.OfType<CodeMemberProperty>().ToList();
foreach (var property in properties)
{
ReplacePropertyByField(type, property);
}
}
}
private static void ReplacePropertyByField(CodeTypeDeclaration type, CodeMemberProperty property)
{
var backingField = GetBackingField(property, type);
backingField.Comments.AddRange(property.Comments);
backingField.Attributes = property.Attributes;
backingField.CustomAttributes = property.CustomAttributes;
backingField.Name = property.Name;
type.Members.Remove(property);
}
private static CodeMemberField GetBackingField(CodeMemberProperty property, CodeTypeDeclaration type)
{
var getterExpression = ((CodeMethodReturnStatement)property.GetStatements[0]).Expression;
var backingFieldName = ((CodeFieldReferenceExpression)getterExpression).FieldName;
return type.Members.OfType<CodeMemberField>().Single(x => x.Name == backingFieldName);
}
