Hello,

You can use SQLCommand[^] to do this. Below code snippet will give you an idea.

C#

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Text;
 

namespace ConsoleApplication10
{
    class Program
    {
        static void Main(string[] args)
        {
            SqlConnection con;
            SqlCommand cmd;
 
            var reader = new StreamReader(File.OpenRead(@"c:\users\afshandc\documents\visual studio 2012\Projects\ConsoleApplication10\ConsoleApplication10\ex.csv"));
            List headers = new List();

            con = new SqlConnection(conString); // Please change the connection string as per your database
            cmd = new SqlCommand("INSERT INTO Currency(code, buying, selling) VALUES(@ccyCode, @buyRate, @sellRate)", con);
            cmd.Parameters.Add("@ccyCode", SqlDbType.VarChar);
            cmd.Parameters.Add("@buyRate", SqlDbType.Decimal);
            cmd.Parameters.Add("@sellRate", SqlDbType.Decimal);
            con.Open();

            while (!reader.EndOfStream)
            {
                var line = reader.ReadLine();
                var values = line.Split(',');
 
                Console.WriteLine(values[0].ToString() + "," + values[1].ToString() + "," + values[2].ToString());
                cmd.Parameters[0].value = values[0];
                cmd.Parameters[1].value = Convert.ToDecimal(values[1]);
                cmd.Parameters[2].value = Convert.ToDecimal(values[2]);
                cmd.ExecuteNonQuery();
            }
            Console.ReadLine();
            con.Close();
        }
    }
}
