Question

With sincere help from experts in this wonderful forum, I have been able to parsed my xml returned by a SharePoint list to get the desired list items into C# Lists.

XDocument xdoc = XDocument.Parse(activeItemData.InnerXml);
XNamespace z = "#RowsetSchema";

List<int> listID = (from row in xdoc.Descendants(z + "row") 
select (int)row.Attribute("ows_ID")).ToList();

List<string> listTitle = (from row in xdoc.Descendants(z + "row") 
select (string)row.Attribute("ows_LinkTitle")).ToList();

I have created a SQL table and I want to insert values in my table using Lists listID and listTitle as parameters

System.Data.SqlClient.SqlConnection sqlConnection1 =
            new System.Data.SqlClient.SqlConnection(MyconnectionString);

            System.Data.SqlClient.SqlCommand cmd = new System.Data.SqlClient.SqlCommand();
            cmd.CommandType = System.Data.CommandType.Text;
            cmd.CommandText = "INSERT TechOpsProjectTracker (ID, [Project Name]) VALUES (@ID, @ProjectName)";

//What I want to do:
            //1. @ID should get the values from the List listID: List<int> listID = (from row in xdoc.Descendants(z + "row") select (int)row.Attribute("ows_ID")).ToList();
            //2. @ProjectName should get the values from the List listTitle: List<string> listTitle = (from row in xdoc.Descendants(z + "row") select (string)row.Attribute("ows_LinkTitle")).ToList();
            //3. so each new record inserted in the table has ID and its corresponding Project Name. Something like this
            /* ID    Project Name
               360   GEI Survey data to Sharepoint
               378   Create back end and environment to support User demographic reporting

There might be some other possibly easier ways to accomplish my job. Please let me know. TIA.

Setup a user defined type similar to.

CREATE TYPE [dbo].[tableOf_Ints] AS TABLE(
    [ID] [int] NULL
)
GO

Then you can can use it like this.

public static SqlCommand CreateCommand(List<int> ints)
{
    var dt = new DataTable();
    dt.Columns.Add("ID",typeof(Int32));
    for (int i = 0; i < ints.Count; i++)
    {
        dt.Rows.Add(ints[i]);
    }

    SqlCommand cmd = new SqlCommand("SomeStoredProc");
    cmd.CommandType = CommandType.StoredProcedure;
    cmd.CommandTimeout = 120;
    var param1 = cmd.Parameters.AddWithValue("@SomeParam", dt);
    param1.SqlDbType = SqlDbType.Structured;
    param1.TypeName = "dbo.tableOf_Ints";

    return cmd;
}

Assuming you have a stored proc like this.

CREATE PROCEDURE [dbo].[SomeStoredProc]  
    @SomeParam TableOf_Ints READONLY
AS
BEGIN
END
