Question

I am trying to find a fast way to find a string in a Column in a DataTable and add it to a comboBox, and this is the code i tried so far :

adapter = new SqlDataAdapter("Select Id_Editeur ID,Libelle_Editeur Editeur from Editeur", myClass.cnx);
            adapter.Fill(myClass.ds, "Editeur");
            foreach (String str in myClass.ds.Tables["Editeur"].Columns[1].ToString())
                editeurBox.Properties.Items.Add(str);

and that’s doesn’t work it gives me this error :

foreach statement cannot operate on variables of type
‘System.Data.DataColumn’ because ‘System.Data.DataColumn’ does not
contain a public definition for ‘GetEnumerator’

How can I do that ? (I don’t want the for loop solution).

Answer 1

foreach (var row in myClass.ds.Tables["Editeur"].AsEnumerable())
{
    editeurBox.Properties.Items.Add(row[1].ToString());
}

or Full linq-style:

editeurBox.Properties.Items.AddRange(
    myClass.ds.Tables["Editeur"]
       .AsEnumerable()
       .Select(dr => dr[1].ToString()
);
