I Had Written As Below:

schoolsList.studentList.Select(x=>(x.Address.Address1).OrderByDescending(x.Address.AddressId)).Distinct().ToList());


It Is Showing

Error:
The type arguments for method
'System.Linq.Enumerable.OrderByDescending<TSource,TKey>(System.Collections.Generic.IEnumerable<TSource>,System.Func<TSource,TKey>)'
cannot be inferred from the usage. Try specifying the type arguments explicitly.

Try

schoolsList
.studentList
.Select(x=>x.Address)
.Select(s=>new {s.Address1, s.AddressId })
.OrderByDescending(o=>o.AddressId)
.Select(x=>x.Address1)
.Distinct()
.ToList();


Hope that helps

Your linq query is wrong it seems.
schoolsList.studentList.Select(x=>(x.Address.Address1).OrderByDescending(x.Address.AddressId)).Distinct().ToList());


It should be
schoolsList.studentList.Select(x=>x.Address.Address1).OrderByDescending(x => x.Address.AddressId)).Distinct().ToList());


Thanks
