asp.net C＃和Linq问题

Question

I have a DropDown list I am trying to pupulate from a DataTable. Each row contains the short date, and the second column contains the month name followed by the year.

Something like this:

6/11/2011      June 2011
7/11/2011      July 2011

I am trying to throw the second column into a drop down list.

dateListDropDown.DataSource = DateList.Rows.Select(x=> x[1].ToString());
dateListDropDown.DataBind();

But I don't think I have the Linq correct.

Can anyone see what I am doing wrong here?

Answer 1

try following (assuming data is not null)

 var list = new List<string>();

 foreach(var row in DateList.Rows)
   list.Add(row[1] as string);

 dateListDropDown.DataSource = list;

As you have mentioned in comments, the error is coming as DataRowCollection does not implement IEnumerable.

Answer 2

Try this:

dateListDropDown.DataSource = DateList.AsEnumerable().Select(x => x[1].ToString());
dateListDropDown.DataBind();

OR

dateListDropDown.DataSource = (from a in DateList.AsEnumerable()
                                         select a).ToList();
dateListDropDown.DataTextField = "YourSecondColumnName";
dateListDropDown.DataBind();
