How to retrieve sort type from the expressions returned by GetOrderingExpressions<T>()?

[sivaji55]

How to retrieve the sort type from expressions returned by GetOrderingExpressions()?, I am trying use which takes the gridify query and parses the order by expression and will create new order by string to consumer another api which supports gridify,
Note: field names are different in other api that supports gridify.

Hi @sivaji55,
I'm not sure if I understand correctly what you're looking for but if you need the target property type, you can use something like this:

var orderingExpression = new GridifyQuery() {OrderBy = "NormalDateTime"}.GetOrderingExpressions<TestModel>();
var unaryExpression = (UnaryExpression) orderingExpression.First().Body;
var targetPropertyType = unaryExpression.Operand.Type;


class TestModel
{
	public DateTime? NormalDateTime { get; set; }
	public DateTimeOffset? DateTimeOffset { get; set; }
}

Hi @alirezanet, I am looking for Sort Direction (Ascending or Descending) in the expression returned by GetOrderingExpressions(); method

I don't think getting the sort type from the ordering expression is possible since it is just a property selector that you can use later in an OrderBy or OrderByDecending methods. feel free to add a feature request if you need this information.
