After I submitted my last post, I realized that everyone might not be able to use that code as is because they might not have a base entity class. No worries. I've ever-so-slightly modified the code to make Trim a standalone method that accepts and returns any object:

public static object Trim(object entity)
{
    Type t = entity.GetType();

    // We're only interested in trimming the public properties, so there is
    // no need to set BindingFlags on the GetProperties call.
    foreach (PropertyInfo pi in t.GetProperties())
    {
        if (pi.PropertyType == Type.GetType("System.String"))
        {
            object currentVal = pi.GetValue(entity, null);
            pi.SetValue(entity, currentVal.ToString().Trim(), null);
        }
    }
    return entity;
}

So assuming you have a Customer entity, you can do something like this (be sure to cast it appropriately):

return (Customer)TrimEntity(myCustomer);
