c# winform get all rows from one column into dictionary and bind to list?

hi all my code below should hopefully explain where im trying to get to if someone could point out the errors and put me in the right direction?

i want all the rows from the column Trades in the Trades Table and get them in a dictionary and bind them

Thanks
Dictionary<string, string> dictATrades = new Dictionary<string, string>();
            foreach (DataRow trade in dataSetMisc.Trades.Rows)
            {
                dictATrades.Add((string)(trade["Trades"]), (string)(trade["Trades"]));
            }
            var dictATradesSort = (from entry in dictATrades orderby entry.Value ascending select entry);

            lstAvailbleTrades.DataSource = new BindingSource(dictATradesSort, null);
            lstAvailbleTrades.DisplayMember = "Value";
            lstAvailbleTrades.ValueMember = "key";

I'm not sure why you need dictionary?
Use list instead.

Replace
this code

Dictionary<string, string> dictATrades = new Dictionary<string, string>();
            foreach (DataRow trade in dataSetMisc.Trades.Rows)
            {
                dictATrades.Add((string)(trade["Trades"]), (string)(trade["Trades"]));
            }
            var dictATradesSort = (from entry in dictATrades orderby entry.Value ascending select entry);

Open in new window


with this one

List<string> dictATrades = (from DataRow trade in dataSetMisc.Trades.Rows select (string)(trade["Trades"])).ToList();
 dictATrades.Sort();

Hi awilderbeast;

I also do not know why you need a Dictionary in this case. I tested your code out and it seems to work fine. Are you receiving errors?

If you are open to another way of doing this using a Dictionary Linq does a nice job.

Dictionary<string, string> dictATrades = ( from t in dataSetMisc.Trades.AsEnumerable( )
                                           orderby t.Field<String>( "Trades" )
                                           select new
                                           {
                                               Key = t.Field<String>( "Trades" ),
                                               Value = t.Field<String>( "Trades" )
                                           } ).ToDictionary( K => K.Key, V => V.Value );

For one thing, you're putting the same value in both the key and value properties of each dictionary element.  Could that be why it's not working for you?
