Question

Can someone help by showing me how to sort a LINQ expression.

I have the following:

 .OrderByDescending(item => item.RowKey)
 .Select((t, index) => new City.Grid()
           {
               PartitionKey = t.PartitionKey,
               RowKey = t.RowKey,
               Row = index + 1,
               ShortTitle = t.ShortTitle,

           })

What I would like to do is to do a sort on the following:

1) First four characters or field RowKey
2) ShortTitle

I am not sure how to do a sort on just a few characters and also not sure how to do a secondary sort.

Answer 1

For the first four characters, include that in your existing statement, then add the ShortTitle afterwards

.OrderByDescending(item => item.RowKey.Substring(0,4))
.ThenBy(item => item.ShortTitle)
