Send (Pass) DataTable as parameter to Stored Procedure in C#

Send (Pass) DataTable as parameter to Stored Procedure in C# 

Database

create a simple table.

 

create a User Defined Table Type in SQL Server using the following query
CREATE TYPE [dbo].[CustomerType] AS TABLE(
      [Id] [int] NULL,
      [Name] [varchar](100) NULL,
      [Country] [varchar](50) NULL
)

Finally the following stored procedure is created which will accept the DataTable as parameter and then will insert all records into the table.

 
CREATE PROCEDURE [dbo].[Insert_Customers]
      @tblCustomers CustomerType READONLY
AS
BEGIN
      SET NOCOUNT ON;
    
      INSERT INTO Customers(CustomerId, Name, Country)
      SELECT Id, Name, Country FROM @tblCustomers
END

protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        DataSet ds = new DataSet();
        ds.ReadXml(Server.MapPath("~/Customers.xml"));

Bulk Insert:

{
    DataTable dt = new DataTable();
    dt.Columns.AddRange(new DataColumn[3] { new DataColumn("Id", typeof(int)),
                    new DataColumn("Name", typeof(string)),

        {
            int id = int.Parse(row.Cells[1].Text);
            string name = row.Cells[2].Text;
            string country = row.Cells[3].Text;
            dt.Rows.Add(id, name, country);
        }
    }
    if (dt.Rows.Count > 0)
    {
        string consString = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
        using (SqlConnection con = new SqlConnection(consString))
        {
            using (SqlCommand cmd = new SqlCommand("Insert_Customers"))
            {
                cmd.CommandType = CommandType.StoredProcedure;
                cmd.Connection = con;
                cmd.Parameters.AddWithValue("@tblCustomers", dt);
                con.Open();
                cmd.ExecuteNonQuery();
                con.Close();
