Feature Request: Filter by property which is passed as a string variable

[prochnowc]

Hi,

I have a use case where the user can enter the name of the property which should be used to filter the result set. Currently this is not possible because

string propertyName = "myProperty";
builder.Filter(e => propertyName == "test")

is being rendered as

propertyName eq 'test'

instead of the wanted

myProperty eq 'test'

Do you think you can add such feature ? Eg. by passing a special static function like so:

Filter(e => ODataProperty.ByName(propertyName) == "value")

Thanks in advance!

Hi!

Please attach a complete usage example, starting with creating an ODataQueryBuilder instance.

Do I understand correctly that there is a need for a dynamic property name?

yes

A complete example would be:

string propertyName = "ODataKind.ODataCode.IdCode";
new ODataQueryBuilder()
  .For<ODataTypeEntity>()
  .ByList()
  .Filter((s,f,_) => f.Property<int>(propertyName) >= 3)
  .ToUri();
