我有以下Transact-sql,我试图转换为LINQ …并挣扎.
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,我想用Lambda表达式来做.
提前致谢！
解决方法
GFrizzle打败了我.但这是一个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;
作为一个纯粹的LINQ方法链版本的奖励：
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 );
