Question

I’m coding in c# on webpages/razor with MS SQL database

I have a table with the following columns

• Sat1
• Sat2
• Sat3
• Sat4
• …
• Sat25

I want to loop through each of these, and assign the value to satAvail

I have the following

for (var i = 1; i < 26; i++)
{
    satWeek = "Sat" + i;
    satAvail = item.satWeek;
}

I want the equivalent of satAvail = item.Sat1;
I’ve tried a few different lines but having no joy

I’m not sure I’m clear on your actual requirement, but in general, when working with the Database helper, if you want to access a column value resulting from a Database.Query or Database.QuerySingle call, you can either do it using dot notation or an indexer.

For example, you may get data doing this:

var db = Database.Open("MyDatabase");
var item = db.QuerySingle("SELECT * FROM Mytable WHERE ID = 1");

If you know want to access the value of a column called Sat1, you would use item.Sat1. However, if the column name is represented as a variable, you would need to use an indexer instead:

var satWeek = "Sat" + "1";
var satAvail = item[satWeek];
