LINQ Expression for casting a primitive datatype?

[powellr0102]

The ERP software my company uses exposes all of its API endpoints as OData services.

I'm attempting to extend the UI with a custom view that emulates how end-users are able to compose queries at runtime.

I'm trying to write a LINQ expression that will generate the following OData Filter where ManufLeadTime is of type decimal :

The expression x => x.ManufLeadTime.ToString().Contains("123") throws a NotSupportedException and decimal doesn't have an explicit/implicit cast to string.

Is this possible or would I need to find another way to accomplish this?

Edit: These are the packages I'm using:

I tried the following expression:
x => ((string)((object)x.ManufLeadTime)).Contains("1");
and it produced
contains(cast(ManufLeadTime,Edm.String),'1')
the client does support casting by means of ConvertExpression, but ToString is a MethodCallExpression which does not support Decimal.ToString

This worked! Thank you!
