hello guys,

I'm working with lists, where i had the need to search about this question:

I'm creating a list with string typed, where carry this list with data picked up from my database like this:

C#

         SqlConnection conn = new SqlConnection (MyConection);
         Conex. Open ();

         SqlCommand comand = new SqlCommand ();
         comand.CommandText = "Select FROM TableX values";

         comand.Connection = conn;

         DrTest comand.ExecuteReader SqlDataReader = ();

         / / create the list
         List <string> myValues = new List ();

         / / Fill the list with values from the Bd
         while (drTest.Read ())
         {
             myValues. Add (drTest ["values"]. ToString ());
         }

This part works perfectly. now i need to do the reverse process which is taking values in a list and insert into my table in the database.

Any help?

Loop through the list like below

C#

foreach(string item in myValues )
{
var value=item;
//insert the value to db here
}

Jameel,
For example, my table that will receive the data table is called Y:
id_tabY is int identity,
string values,

My list is populated this way:
List <string> myValues = new List () {"258632", "369856", "012345", "032165", "211458", "214563", "098796", "574623", "894235",
"313569", "535458", "318954", "838692", "698562", "216898", "021214", "365652", "512489", "865412", "601221"};
values in this list are string

I want to go through this list and add the data in Table Y. will look like after the code
foreach (string item in myValues)
{
var value = item;
/ / insert the value to db here
}

please help me with the code yet because I'm giving my first steps with asp.net.
