Hi @Roberto C , Welcome to Microsoft Q&A,

Using C# to connect to a remote SQL Server database can be achieved through the SqlConnection class.

using System;
using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        // Connection string
        string connectionString = "Server=your_server_address;Database=your_database_name;User Id=your_username;Password=your_password;";

        // Create a connection object
        using (SqlConnection connection = new SqlConnection(connectionString))
        {
            try
            {
                // Open the connection
                connection.Open();
                Console.WriteLine("Connection successful!");

                // Create an SQL command
                string query = "SELECT * FROM YourTableName";
                SqlCommand command = new SqlCommand(query, connection);

                // Execute the command and read the data
                using (SqlDataReader reader = command.ExecuteReader())
                {
                    while (reader.Read())
                    {
                        Console.WriteLine($"{reader["ColumnName"]}");
                    }
                }
            }
            catch (SqlException ex)
            {
                Console.WriteLine("Database operation error: " + ex.Message);
            }
            finally
            {
                // Ensure the connection is closed
                if (connection.State == System.Data.ConnectionState.Open)
                {
                    connection.Close();
                }
            }
        }
    }
}

When using SQL commands, try to use parameterized queries to prevent SQL injection attacks. For example:

string query = "SELECT * FROM YourTableName WHERE ColumnName = @value";
SqlCommand command = new SqlCommand(query, connection);
command.Parameters.AddWithValue("@value", someValue);

Make sure the firewall on the server where the remote SQL Server resides is configured to allow connections from your client IP address. By default, SQL Server uses TCP port 1433.

Best Regards,

Jiale
