How do you find a specific property in WinClient API.

In Classic you could go to the DataRow format and get the property based on the ordinal. How do you do the equiv. with WinClient?

I don't think that there is an equivalent concept in either WinClient or Linq.
 
In Classic, about the only use that I found for the Entity[Ordinal] capability was to assign a value  to a read-only property (e.g., Employee[0] = 1234).  This is a workaround for the problem that Employee.Id = 1234 generates a coimpiler error.  Is this the problem that you are trying to solve?

No.
 
I have a need to compare values on an unknown entities property based on a string.
 
In Classic if you wanted to compare and didn't know the property one way was to say BlahEntity["SomePropert"] == "MyValue".

BlahEntity.EntityAspect["SomePropert"] == "MyValue"

Everything except "pure" properties has been moved off the entity and into EntityAspect, so that intellisense and reflection views of the object aren't cluttered.
