What you are asking for doesn't really match your code: If you want to get a list of the Names from the DataTable, then that's pretty easy if you use Linq methods:

C#

List<string> list = dt.AsEnumerable().Select(r => r["Name"].ToString()).ToList();

Not sure if I understood your question correctly but if you want to get a single string variable containing all the names (with delimiter perhaps) then try something like:

C#

string sVariable = string.Join(",", dt.AsEnumerable().Select(x => x["Name"].ToString()));

Just remember to define

C#

using System.Data;

in order to be able to use the LINQ methods.

Just modify the select portion of the statement. Something like:
string sVariable = string.Join(",", dt.AsEnumerable().Select(x => "'" + x["Name"].ToString() + "'"));
