如何在Expression.Or中设置多于2个表达式

Question

I want to create a query which has more than 3-4 Expression.Or ? But Expression.Or just let me to add two Expressions inside it.

if (!string.IsNullOrEmpty(keyword))
                query
                    .Add(Expression.Or(
                             Expression.Like("Name", keyword, MatchMode.Anywhere),
                             Expression.Like("LastName", keyword, MatchMode.Anywhere)))
                    .Add(Expression.Or(
                             Expression.Like("Email1", keyword, MatchMode.Anywhere),
                             Expression.Like("Email2", keyword, MatchMode.Anywhere)));

The code above generates "Name like %this% or LastName like %this% AND Email1 like %this% and Email2 like %this.

Thanks in advance.

Answer 1

使用Disjunction而不是Or。

Answer 2

You can also use || instead of Or( ) or Disjunction( ).
