Question

I call a GetData call which returned a IQueryable object. I used the following LINQ SelectMany to filter out and selected the fields which I need to
return a List<MyDataType> and I get the following error

Cannot implicitly convert type System.Collections.Generic.List<AnonymousType#1> to System.Collection.Generic.List<MyDataType>

Here is my code

List<CASES> caseList = cs.GetData(foiaNumber).ToList();

Dictionary<int, string> NameDict = 
    caseList.ToDictionary(cases => cases.UID, cases =>     cases.NAME);


List<MyDataType> bindingGrdList = 
    caseList.SelectMany(x => x.ListObject)
        .Select(n => 
            new { 
                   SUBMITTER_NAME = NameDict[n.UID], 
                   NUMBER = n.UID, 
                   DATE_SENT = n.DATE_SENT, 
                   DATE_DUE = n.DATE_DUE, 
                   FINAL_DETERMINATION = n.FINAL_DETERMINATION 
                 }).ToList();

How do I fix the AnonymousType error? thanks.

Replace

n => new { SUBMITTER_NAME = NameDict[n.UID], NUMBER = n.UID,
    DATE_SENT = n.DATE_SENT, DATE_DUE = n.DATE_DUE,
    FINAL_DETERMINATION = n.FINAL_DETERMINATION }

with

n => new MyDataType { SUBMITTER_NAME = NameDict[n.UID], NUMBER = n.UID,
    DATE_SENT = n.DATE_SENT, DATE_DUE = n.DATE_DUE,
    FINAL_DETERMINATION = n.FINAL_DETERMINATION }
