Question

如何翻译linq表达式，例如

var query = (from article in ArticleRepository.GetAll()
            join read in ArticleReadRepository.GetAll() on read.ArticleId equals article.Id
            where article.Id>10
            select new 
            {
                article.Title,
                read.ReadCount
            }).ToList();

进入sql string

select article.Title,
       read.ReadCount 
       from ArticleTable as article 
       join ArticleReadTable as read on read.ArticleId = article.Id 
       where article.Id>10

使用c＃代码

Answer 1

打印query.ToString()，您将看到由LINQ表达式

形成的查询

例如，

var query = from emp in v.Employees
            select emp;
var sqlQuery = query.ToString();
Console.WriteLine(sqlQuery);

结果将是：

SELECT 
[Extent1].[ID] AS [ID], 
[Extent1].[Name] AS [Name]
FROM [dbo].[Employee] AS [Extent1]
