Question

I’m new to LINQ to SQL world – So I’m sorry if the question is stupid 🙂 – I just could not find any answer on the internet:

I have a table with two columns – “Batch_Name” and “Batch_id”.
The user select the batch id and the application needs to return its name.

I have this C# Code to extract the batch name according to the batch id (“myBatchNum”):

        var thisBatch = from x in gridDB.batches
                        where x.batch_id == myBatchNum
                        select new { x.batch_name };


        lblBatchName.Text = thisBatch.First().ToString();

This extract from the proper batch name, but when I try to display the name on a label control, I get this result (“NightBatch is the name in the DB):

{batch_name = NightBatch }

How do I extract the batch name from “thisBatch” properly to the label control?

Thank you so much,
Nim.

It’s unclear that you need to use an anonymous type at all. Just use:

var thisBatch = from x in gridDB.batches
                where x.batch_id == myBatchNum
                select x.batch_name;

lblBatchName.Text = thisBatch.First();

Or if you did want to use an anonymous type still, just use the property you’ve effectively created:

var thisBatch = from x in gridDB.batches
                where x.batch_id == myBatchNum
                select new { x.batch_name };

lblBatchName.Text = thisBatch.First().batch_name;
