LINQ: Passing lambda expression as parameter to be executed and returned by method

by

Something like this:

public IEnumerable<T> ExecuteInContext<T>(
  Expression<Func<T,bool>> predicate)
{
  ... // do your stuff
  //eg
  Table<T> t = GetTable<T>();
  return t.Where(predicate);
}

or

public IEnumerable<T> ExecuteInContext<T>(
   IQueryable<T> src, Expression<Func<T,bool>> predicate)
{
  return src.Where(predicate);
}

Usage:

var r = repo.ExecuteInContext<SomeType>( 
          x => x.SomeProp.Equals(Somevalue));

or 

var r = repo.ExecuteInContext(GetTable<T>(), 
          x => x.SomeProp.Equals(Somevalue));

Assumptions:

  1. Table can be derived from T, else you will need to pass the source too.
  2. You know how to modify the predicate expression if needed.
