Linq, Expressions, NHibernate and Like comparison

Question

I am trying to do a like comparison based on an outside parameter (passed by a search form) that determines type of comparison (\"%string\" or \"string%\"

Answer 1

This is exactly what I had in mind, thank you. I had something similar already written, but it didn't translate to SQL. For example, it worked if I did this directly:

Entity.StringProperty.EndsWith("SearchString");

It didn't work if I used a dedicated method:

CompMethod("BaseString","SearchString",SelectedComparsionType.EndsWith)

I think it probably has something to do with expression evaluation, i'm just not sure what.
