Question

I have the following Transact-Sql that I am trying to convert to LINQ … and struggling.

SELECT * FROM Project WHERE Project.ProjectId IN (SELECT ProjectId FROM ProjectMember Where MemberId = 'a45bd16d-9be0-421b-b5bf-143d334c8155') 

Any help would be greatly appreciated … I would like to do it with Lambda expressions, if possible.

Thanks in advance!

GFrizzle beat me to it. But here is a C# version

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; 

And as a bonus a purely LINQ method chain version as well:

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 );
