Iam using VS 2008
I want to add country in Dropdownlist.
I have used following code:
List<string> Country = GetCountryList();

var sortedCountry = from c in Country orderby c select c;
// var sortedCountry = from c in Country orderby c select c;
ddlCountry.DataSource = sortedCountry;
ddlCountry.DataBind();

But iam facing error on line:var sortedCountry = from c in Country orderby c select c;
I have also used foll. namespaces:
using System.Collections.Generic;
using System.Globalization;
using System.Linq;

Accepted answer
check the target framework your project using.
if its 3.0 then change to 3.5 and complie the code.

I tested your code; it works for me, therefore it is likely the code that precedes the LINQ statement has an error. The errors are saying that a semicolon is missing, so I would look at the code preceding the LINQ.

This code should work. Manikavellu is correct.

           IList _country = new List();
            _country.Add("India");
            _country.Add("US");
            _country.Add("China");
            _country.Add("Zimbabwe");

            var query = from c in _country
                        orderby c
                        select c;

            DropDownList1.DataSource = query;
            DropDownList1.DataBind();

Below code works fine, just try this;

List<string> s = new List<string>();
s.Add("Manik");
s.Add("Babu");
s.Add("Velu");
var s1 = from s2 in s orderby s2 select s2;
DropDownList1.DataSource = s1;
DropDownList1.DataBind();

Can you paste the error ?, It will be easier to provide the solution by seeing the exact error.
