LINQ有两个或多个查询? [英] LINQ with two or more queries?

问题描述

我们如何在linq语句中使用两个或多个查询.

How we can use two or more queries in a linq statement.

推荐答案

如果我正确理解了您的声明，那么我认为您想执行两种不同的操作，例如预测和订购.

例如-我需要获得所有客户，然后我需要根据公司名称进行排序.

然后

LINQ查询-

Hi,

If i understood your statement properly, then i am thinking that you want to perform two different actions such as projections and Ordering.

For instance - I need to get all the customers and then i need to sort based on Company name.

Then

LINQ Query -

context.Customers.Select(c => c).OrderBy(c => c.CompanyName).ToList();

问候，

此语句等效于查询的where 条款中的AND功能

This statement does the equivalent of AND function in the where clause of a query

query = from b in query
select b;

query = query.where(col => col.Title.Contains(title));
query = query.where(col => col.Author.Contains(author)
