TranslateAttribute attr,
CodeMemberMethod method, CodeParameterDeclarationExpression from,
Func<Type, Type, TranslateAttribute> getTypesTranslateAttributeFn)
{
method.Statements.Add(from.ReturnNullIfNull());
// targetType to = new T();
var to = attr.SourceType.DeclareVar("to");
method.Statements.Add(to);
var fromTargetTypePropertyNames = attr.TargetType.GetProperties().ToList().Select(x => x.Name);
foreach (var toSourceTypeProperty in attr.SourceType.GetProperties())
{
if (!fromTargetTypePropertyNames.Contains(toSourceTypeProperty.Name)) continue;
method.Statements.Add(CreateToSourceAssignmentMethod(attr, to, toSourceTypeProperty, from, getTypesTranslateAttributeFn));
}
method.Statements.Add(to.Return());
return method;
