DataTable to observable collection

Question

I have been googling and searching for the answers here, but I still fail to understand a very basic thing - How to convert a DataTable to an Observable Collection?

Answer 1

I had a little issue with the accepted solution. It does not allow the [] brackets on type var.

var test = new ObservableCollection<Test>();
foreach(DataRow row in TestTable.Rows)
{
    test.Add(new Test()
    {
        id_test = (int)row["id_test"],
        name = (string)row["name"],
     });
 }

Answer 2

You don't want to create a new collection for each row in the table, but rather one collection for the entire table (with one object in the collection created for one row in the table):

var test = new ObservableCollection<Test>();
foreach(var row in TestTable.Rows)
{
    var obj = new Test()
    {
        id_test = (int)row["id_test"],
        name = (string)row["name"]
    };
    test.Add(obj);
}
