我有以下Transact-Sql,我正尝试将其转换为LINQ ...并正在挣扎。
SELECT * FROM Project
WHERE Project.ProjectId IN (SELECT ProjectId FROM ProjectMember Where MemberId = 'a45bd16d-9be0-421b-b5bf-143d334c8155')
任何帮助将不胜感激...如果可能的话,我想使用Lambda表达式来做。
提前致谢!
最佳答案
GFrizzle击败了我。但是这是一个C#版本
var projectsMemberWorkedOn = from p in Projects
join projectMember in ProjectMembers on
p.ProjectId equals projectMember.ProjectId
where projectMember.MemberId == "a45bd16d-9be0-421b-b5bf-143d334c8155"
select p;
作为奖励,还有纯LINQ方法链版本:
var projectsMemberWorkedOn =
Projects.Join( ProjectMembers, p => p.ProjectId, projectMember => projectMember.ProjectId,
( p, projectMember ) => new { p, projectMember } )
.Where( @t => @t.projectMember.MemberId == "a45bd16d-9be0-421b-b5bf-143d334c8155" )
.Select(@t => @t.p );
