Cannot convert system.generic.list anonymous type-CodePudding

I have a class I want to populate from a Linq query, but I am using a sub select statement to slightly alter the properties of the list. I have a class it should fit into but it refuses to go in. I am wondering if there is a way I can get these results to fit into the list as I defined it rather than a generic anonymous type.

public class SCADA_DATA_Truncated
        {
            public string acode { get; set; }
            public string LOCCODE { get; set; }
            public Nullable<System.DateTime> COLDATE { get; set; }
            public string RESULT { get; set; }
            public string analyte { get; set; }

            
        }

And here is where I am attempting to populate the data:

List<SCADA_DATA_Truncated> dataResults = (SCADA_DATA_Truncated)(from b in a2Entity.SCADA_DATA
                                           where DbFunctions.TruncateTime(b.COLDATE) >= dateCheck1 && DbFunctions.TruncateTime(b.COLDATE) <= dateCheck2
                                           && whereInAcode.Contains(b.acode) && whereInLoc.Contains(b.LOCCODE)
                                           select new
                                           {
                                               COLDATE = DbFunctions.TruncateTime(b.COLDATE),
                                               acode = b.acode,
                                               LOCCODE = b.LOCCODE,
                                               RESULT = b.RESULT,
                                               analyte = b.analyte
                                           }
                                       ).ToList();

CodePudding user response：

This is an anonymous type:

select new 
{
     COLDATE = DbFunctions.TruncateTime(b.COLDATE),
           acode = b.acode,
           LOCCODE = b.LOCCODE,
           RESULT = b.RESULT,
           analyte = b.analyte
}

The runtime has no idea how to convert it to your class

Why not changing it to

select new SCADA_DATA_Truncated
{
      COLDATE = DbFunctions.TruncateTime(b.COLDATE),
               acode = b.acode,
               LOCCODE = b.LOCCODE,
               RESULT = b.RESULT,
               analyte = b.analyte
}

You can then remove the explicit cast altogether
