You cannot call .ToString on a DataRow object. You'll get a string that says "System.Data.DataRow", not some representation of your data.

You're not providing enough information to give you any sensible answer. What EXACTLY do you want in the List and what does the source data look like?

Why not something like:

C#

string connString = @"your connection string here";
string query = "select * from table";

SqlConnection conn = new SqlConnection(connString);
SqlCommand cmd = new SqlCommand(query, conn);
conn.Open();

// create a data adapter
SqlDataAdapter da = new SqlDataAdapter(cmd);

// this will query your database and return the result to your data table
da.Fill(dataTable);

conn.Close();
da.Dispose();

NOTES:
* The data table field must be initialized before calling da.Fill(dataTable)
