        foreach (var objId in modelSpace)

            var entity = transaction.GetObject(objId, OpenMode.ForRead);
            Hatch hatch = entity as Hatch;
            if (hatch == null)
                continue; //not hatch

            acDoc.Editor.WriteMessage("\nFound Hatch Area={0}", hatch.Area);
        }            
    }
}

Hatch hatch = entity as Hatch;
if (hatch == null)
continue; //not hatch
MText actext = new MText();
actext.SetDatabaseDefaults();
actext.Height = 16;
actext.Width = 2;

actext.Contents = ("\n The area of hatch is =" + hatch.Area);
acDoc.Editor.WriteMessage("\n The area of hatch is:" + hatch.Area);

modelSpace.AppendEntity(actext);
transaction.AddNewlyCreatedDBObject(actext, true);
}
transaction.Commit();
}
}
}
}

try this

C#

[CommandMethod("FindAllHatches")]
public static void FindAllHatches()
{
    Document acDoc = Application.DocumentManager.MdiActiveDocument;
 var str=new StringBuilder();
    str.Append("\nSearching for Hatches");
 
    var db = acDoc.Database;
    using (Transaction transaction = db.TransactionManager.StartTransaction())
    {
        ObjectId idModelSpace = SymbolUtilityServices.GetBlockModelSpaceId(db);
 
        BlockTableRecord modelSpace = transaction.GetObject(idModelSpace, OpenMode.ForRead) as
            BlockTableRecord;
 
        foreach (var objId in modelSpace)
        {
            var entity = transaction.GetObject(objId, OpenMode.ForRead);
            Hatch hatch = entity as Hatch;
            if (hatch == null)
                continue; //not hatch

           str.Append("\nFound Hatch Area={0}", hatch.Area);
        } 
 acDoc.Editor.WriteMessage(str.ToString());           
    }
}
