Select multiple columns using Entity Framework

Question

Maybe an easy question, but can\'t find it easily so forgive me =) I try to select multiple columns. The statement I use is:

var dataset2 = from recordset in ent         


        

Answer 1

You either want to select an anonymous type:

var dataset2 = from recordset 
               in entities.processlists 
               where recordset.ProcessName == processname 
               select new 
               {
                recordset.ServerName, 
                recordset.ProcessID, 
                recordset.Username
               };

But you cannot cast that to another type, so I guess you want something like this:

var dataset2 = from recordset 
               in entities.processlists 
               where recordset.ProcessName == processname 

               // Select new concrete type
               select new PInfo
               {
                ServerName = recordset.ServerName, 
                ProcessID = recordset.ProcessID, 
                Username = recordset.Username
               };
